Most first-time visitors wondering about things to do in the Florida Keys start and end with Key West. They book a few nights, maybe glance at a map, and figure that covers it. The reality is that the Keys stretch 125 miles from Key Largo to the end of US-1, and every segment of that drive has something the others don’t. The reefs near Key Largo are different from the reefs near Big Pine. The pace of Marathon is nothing like the energy of Key West (mellow vs super active). Miss any of it and you’ve only seen part of the picture. And then there’s us: we will stop EVERYWHERE and do EVERYTHING.
What the Keys actually offer spans living coral reefs, endangered wildlife found nowhere else on earth, Civil War fortresses only reachable by boat, and sunsets that draw crowds every single evening as a kind of ritual (we’ll talk about Sunset Celebration below). Florida Keys attractions vary widely depending on where you are on the island chain, which is exactly why this guide breaks everything down town by town. From Key Largo through Islamorada, Marathon, Big Pine Key, and Key West, you’ll find enough here to build a trip that fits your group instead of a generic checklist, whether you have one day or two weeks. Like always, if you have any questions or need additional recommendations, please leave a comment or send us a note. We’re always happy to share more and help you plan a great Florida Keys trip!
Things to Do in Key Largo and Islamorada: Where Your Florida Keys Trip Should Begin
It makes sense to start in Key Largo with our grand list of things to do in the Florida Keys as it’s where you’ll first get the Keys vibes as you’re driving from Miami or just I-95 in general. This is some of the best snorkeling in the Florida Keys. As a Floridian, Key Largo is my favorite, and I think it will be yours too, so take a look and see what you want to enjoy while you’re here.
If you’re treating the Upper Keys as an overnight stay rather than a morning pass-through, that’s the right call. A night in Key Largo or Islamorada means a morning snorkel at Pennekamp before the crowds build, a relaxed lunch in the village, and a real afternoon at the reef instead of a rushed two-hour sprint. We always like to have two nights in Key Largo to enjoy the activities and spend time out on the water.
Snorkeling and Diving in the Upper Keys Reefs
First up is one of my favorite state parks in all of Florida: John Pennekamp Coral Reef State Park in Key Largo anchors the upper Keys for good reason. It was the first undersea park established in the United States, and it protects some of the most accessible reef systems in the entire Florida Keys National Marine Sanctuary. Molasses Reef and the submerged Christ of the Abyss statue are the headline stops, with guided snorkel tours departing four to five times daily between 9:00 AM and 3:00 PM. Adult snorkel tour tickets run $38.95 to $49.95; park entrance for a vehicle with multiple passengers is $8.00 plus $0.50 per person. And if that’s not your thing, there is a really fun glass bottom boat catamaran that takes visitors to the reef and you can see lots of wildlife from it too!
Pennekamp State Park has more than Molasses Reef. If you’re a first-timer, Grecian Rocks and Carysfort Lighthouse Reef offer calm, shallow water that rewards beginners without overwhelming them. Experienced snorkelers and divers can also look further south: Alligator Reef near Islamorada adds depth and genuine species variety, and Looe Key (covered below in the lower Keys section) is in a league of its own. Book snorkel tours at least 48 hours ahead in peak season; slots at Pennekamp fill fast, and Alligator Reef tours are no different. There are lots of other snorkeling options from Key Largo, so book the one that fits with your schedule and meets your snorkeling level. Horizon Divers and Amoray Dive Resort both have good options for advanced snorkelers. Also, stop into the REEF Ocean Exploration Center to learn a little about the fish you’ll be seeing!
Tip: if you have first-time snorkelers, visit the Marine Lab for a guided snorkeling tour with a marine biologist. This is a great way to get kids comfortable with seeing underwater and interacting with fish.
Florida Keys Wild Bird Sanctuary
The Florida Keys Wild Bird Rehabilitation Center in Key Largo deserves more attention than it gets. It’s free (by donation), open sunrise to sunset, and the birds in residence are all recovering from injuries rather than living as display animals. For families or solo travelers who want a quiet experience away from the boat traffic, the bird sanctuary consistently earns its place on any Upper Keys itinerary with its chill vibes and beautiful birds (including owls). Arrive early for the best activity, and bring water since shade isn’t available throughout the entire center.
Swimming with Dolphins
I used to not be a supporter of dolphin swimming experiences and then we visited a dolphin facility and learned about the research, human-dolphin relationships, and voluntary interactions. Talking with trainers and seeing how much they love and care for their dolphins changed my view, and now we try to support dolphin work whenever we can. Both Dolphin Life Key Largo and Dolphins Plus Bayside are great organizations that use swimming with dolphins to teach people about conservation and develop a love for marine wildlife.
Wildlife Encounter Worth Your Time: Tarpon at Robbie’s
I know this is cliched and you might roll your eyes, but Robbie’s of Islamorada offers one of the most genuinely memorable wildlife experiences in the Keys: feeding giant tarpon by hand from the dock. These fish are enormous, completely wild, and completely unforgettable. It costs almost nothing and takes about 20 minutes, making it an easy add to any morning or afternoon. We’ve seen more than tarpon doing this, including sharks and there was even a crocodile at Robbie’s once!
Beaches and Waterfront Access
Yes! There are some good spots on Key Largo and Islamorada where you can access the water without a tour. While the Keys aren’t really a beach destination, there are some spots that you can get in and enjoy the sunshine and even have some great snorkeling. Rowell’s Waterfront park is an old quarry pit with lots of wildlife, Founder’s Park in Islamorada has a good beach and great snorkeling, and Harry Harris Beach Park in Tavernier is awesome on a calm day. Get all the details on the beaches of Key Largo here!
Upper Florida Keys State Parks
Florida State Parks area great spots to enjoy a little nature, and the Upper Keys actually have quite a few. I’ve mentioned John Pennekamp Coral Reef State Park, but there are several more:
- Dagny Johnson Key Largo Hammock Botanical State Park – walking trails and wildlife
- Windley Key Fossil Reef State Park – historic exhibits and fossils
- Long Key State Park – walking trails and birding
- Lignumvitae Key Botanical State Park – accessible by boat from Islamorada
Museums in the Upper Keys
It’s always good to have some things to do for when it’s raining in the Florida Keys… or when you need to get out of the heat. There are a few museums you may want to check out when you’re here, especially if you need to escape some weather. On Islamorada, the History of Diving Museum is really interesting, and actually surprisingly good with kids. The Keys History Discovery Center, also on Islamorada, is another one and I like their film series they show throughout the day. Also, I mentioned the REEF Ocean Exploration Center before, and it is another good place to stop for a little learning or to cool off when you’re on Key Largo.
Upper Keys Dining Ideas
Dockside dining in the Upper Keys is casual, fresh, and completely unpretentious. In Islamorada, Islamorada Fish Company sits directly on Florida Bay with a dockside patio and seafood sourced close to where you’re sitting. Square Grouper offers a step up in creativity (and price), with waterfront seating where manatees occasionally cruise through the shallows below. Lorelei Restaurant and Cabana Bar is the go-to for sunset views with cold drinks and inexpensive food. Also, my two favorite slices of Key Lime Pie are in the Upper Keys: Skipper’s Dockside (Key Largo) and Papa Joe’s (Islamorada).
Things to Do in the Florida Keys: Marathon and the Middle Keys
As you continue driving south on the Overseas Highway, you get to the Middle Keys of which the most well known is Marathon. This is where we go when we want to have a quiet trip. Marathon is so chill and has some of our favorite resort hotels. And the snorkeling and kayaking are great too.
The Turtle Hospital and Dolphin Research Center
The Turtle Hospital in Marathon is a working sea turtle rescue and rehabilitation facility, not an aquarium or a show. Daily tours walk visitors through the process of rescue, treatment, and release, and the turtles in residence are all mid-recovery patients. There’s no age limit, the tour is genuinely educational for adults and kids alike, and reservations are recommended since tour capacity is limited. It’s one of the most consistently praised stops anywhere along the Overseas Highway.
The Dolphin Research Center, a short drive from the Turtle Hospital, offers swim-with-dolphin programs that are conservation-forward rather than purely commercial. The full Dolphin Encounter costs $249 per person and requires participants to be at least five years old, with children ages five to seven needing an accompanying adult in the water. For younger families, the Family Dolphin Splash runs $66 per person (2026) and welcomes children as young as three. The center is fully accessible and offers inclusive programming for visitors with special needs. Pairing both stops in a single morning makes Marathon worth an overnight stay on its own.
The Seven Mile Bridge and Bahia Honda State Park
The Seven Mile Bridge is more than scenery. It runs over the corridor where Henry Flagler built his Overseas Railroad in the early 1900s, and the original bridge structure runs parallel to the current roadway… but it is NOT drivable. It’s literally missing chunks. Driving the Seven Mile Bridge on a clear morning, with open water stretching in both directions, is one of those Florida Keys moments that earns its reputation. Slow down, pull over at the rest area on the south end of the bridge, and take it in properly.
Before you get to the Seven Mile Bridge though if you’re coming from Marathon is Historic Pigeon Key. This is one part sightseeing, one part history center, and one part snorkeling destination. You can bike or walk to Pigeon Key for free, but to access the island you need to pay a fee, so you might as well do the fun tram out to the island.
Bahia Honda State Park, at Mile Marker 37, holds the best genuine beach in the Florida Keys, with white sand, clear water, shore snorkeling, and exceptional birdwatching for species like the white-crowned pigeon and great white heron. Day visits require no reservation, and the vehicle entrance fee runs $8 to $10. Camping is another story: sites book out months in advance, so reserve early if you want to stay overnight. Bahia Honda makes a natural afternoon anchor between Marathon and Key West, and skipping it is one of the most common planning mistakes first-timers make.
Sombrero Beach and the quiet side of Marathon
Sombrero Beach is where Marathon locals actually swim. It’s calm, shallow at the entry, and well-suited for young kids who need a gentler setup than open-water snorkel tours offer. There is also an awesome playground here at Sombrero Beach. After a full water day, Marathon’s marina district has some good dockside dining options where the atmosphere is low-key and the fish is local. It’s the kind of place that people who slow down long enough to enjoy it always want to come back to.
Curry Hammock State Park
Whether you’re looking to have a beach day or you want what I think is the best kayaking trail in the Florida Keys, Curry Hammock State Park has lots of things to do. Located at the north end of Marathon, this is our go-to spot for a quiet afternoon in nature where we also know we can relax and enjoy a picnic too. The peace and quiet paired with the wildlife make Curry Hammock a winning activities in the Florida Keys.
Crane Point Hammock Preserve
I’m always excited to tell people about Crane Point Hammock because it’s such a fun place to visit. One of the best things to do when you’re on Marathon, Crane Point has walking trails, a nature center, some historic structures, and a natural fish pedicure station. That’s right, you just sit on the dock and the fish nibble at your feet. If you get here early enough, you can also rent kayaks and snorkeling gear for the day.
Marathon Mermaid Sandbar Tours
One of the best things to do in the Florida Keys is hang out on a sandbar, and most people wait to do this until they get to Key West. The Marathon Mermaid is a small platform boat that takes you out to the Valhalla Sandbar and it’s just the most fun you can have out in the water. The shallows are full of wildlife, you can play frisbee in the water, there’s snorkeling, or you can just float. It’s the perfect morning or afternoon activity on Marathon.
Big Pine Key and the Lower Keys: The Quietest Stretch of the Island Chain
If you’re doing the drive from Key Largo to Key West on the Overseas Highway, by the time you get to Big Pine Key, you’re just ready to be in Key West and relax, but there are some wonderful things to do and places to visit in this part of the Florida Keys. Give yourself time on the way into or out of Key West to have some fun and check out the sights and activities in these quietest of the Keys.
Spotting Key Deer at the National Key Deer Refuge
Big Pine Key surprises most travelers who assume it’s a pass-through between Bahia Honda and Key West, which is it, but it’s more. The National Key Deer Refuge protects the only population of Key Deer on earth, a miniature subspecies of the white-tailed deer that stands about 26 inches tall at the shoulder. Early morning and late afternoon are the best viewing windows, and the paved refuge roads make this accessible for families with strollers and visitors with mobility needs. Feeding or approaching the deer is prohibited, and the refuge takes that seriously. You’ll see people do it, but please do not follow their example.
The best place to consistently see Key Deer is around the Blue Hole area. Walk the trail around the Blue Hole, watch for Key Deer and birds, and if you’re lucky, you might even see the alligators that live there. And no, the alligators aren’t native to the Florida Keys, but were put here by humans and now they just live their peaceful gator lives.
Looe Key and world-class snorkeling off the lower Keys
Looe Key Reef is one of the most biologically rich reef systems in the entire Florida Keys National Marine Sanctuary. Goliath groupers and reef sharks are common encounters here, and coral coverage remains exceptional. This reef rewards experienced snorkelers most, though organized tours through local operators make it accessible for visitors at a range of skill levels. If you’ve already snorkeled Pennekamp and want something with more depth and marine life density, Looe Key delivers.
Note: we’ve done Looe Key Reef with our kids when they were very young too. On a calm day, this is actually one of the best open water snorkels you can do with kids because there is so much Florida Keys wildlife.
Pine Channel Nature Park
This is one of the most overlooked spots in the Florida Keys and I think coming here is one of the best things to do in the Lower Keys. First of all, this is THE BEST picnic area in the area with lots of shaded tables, restroom facilities and water access points. The snorkeling here is some of the most unusual and best in the Lower Keys. This is where I like to visit for photographing nudibranchs and seahorses. It’s just the coolest, most surprising snorkeling.
Why the lower Keys deserve more than a pass-through
The character shift between the Middle and Lower Keys is real. There are fewer crowds, more birds, and a slower pace. You get a sense that you’ve moved past the tourist corridor into something untapped and peaceful. The visitors who rush this stretch to reach Key West faster usually say they wish they would’ve spent some time here. Give the Lower Keys an afternoon, or better yet a full day, and the Florida Keys road trip becomes a different kind of experience entirely. If you’re interested in kayaking in the Florida Keys, you’ll see that there are some wonderful spots here that you’ll miss if you just breeze through.
Key West: Sunsets, History, and the End of the Road
Who doesn’t love Key West? It’s fun and beautiful, there are tons of things to do no matter what interests you, and the food scene is the best in the Keys. When it comes to activities in Key West, there are some standards that are iconic of being here, so lean into the touristy side of things a little and have extra fun in Key West.
Mallory Square and the sunset sailing tradition
The Mallory Square Sunset Celebration happens every evening and functions as a genuine community ritual rather than just a tourist stop. Yes, you’ll absolutely see fire breathers, street performers, and some local vendors, but the communal energy of a crowd watching the sun drop behind the Gulf is great. It’s free, it’s festive, and it sets the tone for everything else Key West does well. Arrive 30 to 45 minutes before sunset to find a good spot and work the perimeter of the vendors first.
The other way to enjoy the famous Key West sunset is on a boat. Sunset sails on historic schooners and catamarans are the elevated version of the same experience. Several operators run 90-minute to two-hour sails with open bars, live music, and hors d’oeuvres, with tickets typically ranging from $59 to $90 per person depending on the cruise. The Commotion on the Ocean catamaran and the Blue Q BYOB sailing are my favorites. Sunset sail tickets sell out, especially in winter. Book the day you arrive at a minimum, and book further ahead if your trip falls between December and April.
History that runs deeper than Duval Street
Fort Zachary Taylor Historic State Park combines the best beach in Key West with a well-preserved Civil War-era fort. Cannons, soldier quarters, and exhibits on the fort’s role in the Union blockade sit alongside turquoise water ideal for shore snorkeling. The Hemingway House on Whitehead Street covers the literary history, and the Southernmost Point marker at the corner of South and Whitehead is a classic Key West bucket-list photo. Plan at least two days in Key West rather than one: what gets cut on a one-day visit is always something you’ll wish you had seen.
More ways to dig into history while you’re in Key West include visiting the other historic sites, many of which are along the Old Town Trolley Tour route or that you’ll pass while you’re on the Conch Train Tour or Ghosts and Gravestones Tour. The Key West Lighthouse, Audubon House, Key West Shipwreck and Treasure Museum, Key West Art and History Museum, Mel Fisher Maritime Museum and Truman’s Little Whitehouse are all interesting and in the same neighborhood, so it’s really easy to visit them.
Dry Tortugas: the day trip that earns its effort
Dry Tortugas National Park sits 68 miles west of Key West in open water and is only reachable by ferry or seaplane. The Yankee Freedom III departs daily at 8:00 AM, arrives at Fort Jefferson around 10:15 AM, and returns by 5:15 PM. Adult ferry tickets run $220 to $235 and include breakfast, lunch, the park entrance fee, and snorkel gear. The seaplane option costs significantly more and suits travelers with tighter schedules and larger budgets.
If visiting Dry Tortugas National Park is important to you, the booking reality here is non-negotiable: ferry capacity is 175 passengers per day, and tickets sell out. Book two or more months in advance for day trips. Camping reservations require eight to twelve months of lead time. Dry Tortugas is the kind of place that rewards planning specifically because so few visitors put in the work to get there. I love it. My kids love it. You’ll love it!
Building a Florida Keys Itinerary Around Your Trip Length
I wish we all had 10 days that we could just slowly move through the Florida Keys doing all the fun things and enjoying the quiet waterways, but sometime you just a a day tacked onto your Miami trip, or maybe a week for family vacation. We have some suggestions for how best to plan an itinerary depending on how much time you have.
1-day drive: Key Largo to Key West without missing the essentials
Driving the route from Key Largo to Key West takes about two and a half hours non-stop, but four to five hours with real stops built in. A functional one-day flow if you are in the Keys just for a 12-16 hour visit: a Pennekamp snorkel tour in the morning, the Turtle Hospital at midday, Bahia Honda State Park in the afternoon, and the walking Whitehead or Duval Street and then Mallory Square for sunset. The Key Deer Refuge and Robbie’s Marina don’t make a one-day cut, and that’s fine, save them for next time.
3-day and 7-day Itineraries that actually work
For three days, split it this way: Upper Keys on day one with a snorkel tour and Robbie’s; Marathon and Bahia Honda on day two; Key West for day three. Simple, fun and easy to add onto a trip to Miami or Everglades National Park. For seven days, the full itinerary easily works as follows: two nights in Key Largo, one night in Islamorada, one night in Marathon, one night near Big Pine or Bahia Honda, and two nights in Key West with the Dry Tortugas ferry as the day-six anchor. This pacing gives each stretch of the Keys enough time to enjoy the Florida Keys well and a week lets you see what makes it such a different Florida destination from the others.
Our town-by-town guides function as the research layer under each of these itineraries, covering specific hotels, tour operators, and dining options across every budget. If you want the full planning picture to do any section of these suggestions, dig into each location here on The Keys Explored.
Costs and Booking Windows to Plan Around
Here’s a quick reference for activities that need advance reservations:
- Dry Tortugas ferry: $220, $235 per adult; book 2+ months ahead
- Sunset sails: $59, $90 per adult; book the day you arrive at minimum
- Dolphin encounters: $66 to $249 depending on program; reserve online before arrival
- Florida State Parks camping: $25, $35 per night; reserve 3, 6 months ahead via Florida State Parks
- Pennekamp snorkel tours: $38.95, $49.95 per adult; book 48+ hours ahead in season
Walk-in activities include Mallory Square, the Key Deer Refuge, Robbie’s tarpon feeding, the Florida Keys Wild Bird Rehabilitation Center, and Fort Zachary Taylor day visits, and many other singular tourist sites. These don’t require any planning beyond showing up, which is a useful pressure valve when the rest of your trip is built around reservations.
What to Know Before You Go
You can, of course, just decide to visit the Florida Keys if you’re in Miami or having a Florida vacation, but it’s best when you do plan. Things are usually less expensive with planning, and if you can visit Monday through Friday, you’ll find the best hotel deals.
Best time to visit and what changes by season
Winter, from December through April, is peak season in the Keys: best weather, lowest humidity, and the strongest travel demand, even though the water temperature drops significantly and snorkeling is a bit chilly. Expect higher prices and the need to book accommodations and tours well in advance. Summer brings off-season rates (I know, that’s counter-intuitive) and a more local crowd, but the heat and humidity are really intense, and June through November falls within hurricane season, which a lot of people just don’t want to risk the potential of a storm hitting. The shoulder months of May, October, and November represent the sweet spot for visiting the Florida Keys as you get more solid weather with fewer crowds and better pricing.
Things to do in the Florida Keys with Kids: family logistics and accessibility notes
Age limits matter for different snorkeling tours and dolphin programs. For example, the Dolphin Research Center requires participants to be at least five years old for the full swim encounter, and children ages five to seven need an adult in the water. Some snorkel tours are more advanced and while they may not have age restrictions, the nature of the bigger open water trips is a more intermediate experience. Places like the Turtle Hospital have no age limit and work well for all ages.
For accessibility, some operators run lift-equipped snorkel boats out of Key Largo and Key West, but you’ll want to confirm availability directly before booking, since not every vessel is equipped. The Dolphin Life Key Largo and the Dolphin Research Center offer inclusive programming for visitors with special needs. And then beach wheelchairs are available at Bahia Honda State Park and some other spots with advance requests. The Keys are working towards being welcoming for visitors who need more accessibility assistance, but some tours and activities just aren’t there quite yet.
Protecting the Reef and the Community You’re Visiting
Reef-safe sunscreen isn’t a suggestion in the Florida Keys National Marine Sanctuary: oxybenzone and octinoxate are known reef toxins and are regulated in Monroe County. Bring mineral-based sunscreen and leave the chemical formulas at home. Most snorkeling tours you go on will provide reef-safe sunblock onboard, so take advantage of it.
The Keys also have a strong catch-and-release fishing culture, driven by the understanding that healthy fish populations are what make the fishery worth visiting in the first place. Both locals and fishing guides practice it. When you book tours and activities, choose to book through local operators over large aggregator platforms (OTAs like Tripadvisor). More money stays in the community, the guides get more for their hard work, and the experiences stay consistently good.
Start Planning Your Florida Keys Trip Town by Town
There are more things to do in the Florida Keys than most visitors expect, spread across more places than most itineraries ever explore. The best trips here aren’t built around a single highlight, they’re built on honest expectations (including remembering that beaches are NOT the primary activity), good timing, and knowing which activities fit your group’s interests and energy level. A family with young kids and an experienced diving couple will plan completely different trips through the same 125-mile stretch, and both can be exceptional… and then they can meet up for dinner at the end of each day.
For the deeper planning layer behind this guide, we cover every town with dedicated hotel reviews, tour recommendations, and activity guides built around the same approach you’ve seen here. Use the town guides to build out the specifics once you’ve settled on your framework. Key Largo — Islamorada — Marathon — Key West
Pick one town that speaks to you and start there. When it comes to things to do in the Florida Keys, the Overseas Highway connects everything else and is full of roadside attractions, and the Keys have a way of making you want to come back for what you missed the first time. If you have any questions about our recommendations or need additional suggestions, please leave a comment or send us a note. We’re always happy to share more and help you plan a great time exploring the Keys!
