What is Marathon Florida known for?

Marathon is the sportfishing capital of the Keys — the waters around the Middle and Lower Keys have some of the best tarpon, bonefish, and permit fishing in Florida. It's also the location of the Turtle Hospital (the only state-certified sea turtle rehabilitation center in Florida), Sombrero Reef (one of the best snorkeling reefs in the Keys), and the Bahia Honda State Park beaches. Marathon sits at mile marker 50 on US-1 — hence the name.

Is Marathon a good place to snorkel?

Yes — better than Key West for snorkeling. Sombrero Reef is the standout (protected within the Florida Keys National Marine Sanctuary), and there are several other sites accessible from Marathon that are less crowded than the Key West reef sites.

Day Trip to Marathon — The Florida Keys at Its Most Livable (2026)

Q: How far is Marathon from Key West and how long does it take to drive?

Marathon is roughly 45 miles north of Key West along the Overseas Highway (US-1). At typical speeds with some lights, it takes about 50–65 minutes. The drive itself is scenic — you're on the water most of the way, with views across the bay and the Seven Mile Bridge. Don't speed; the Monroe County sheriff patrols the Overseas Highway regularly.

Point the car north from Key West and in under an hour you're somewhere the Keys still feel like a working fishing town. Marathon sits at mile marker 50 on US-1 — roughly 50 miles north of Key West, 50 miles south of Key Largo. It was built on fishing, and that DNA is still all over the harbor, the tournaments, and the restaurants that feed the charter fleet. Less polished than Key West, more local than Key Largo, and the snorkeling beats both.

The day trip is easy — the drive is scenic and takes under an hour. Here's how to spend the day once you're there.

The Turtle Hospital

Start here — it's the most educational stop in Marathon, and the one people talk about afterward. The Turtle Hospital has been rehabilitating sea turtles since 1985 and is the only state-certified sea turtle rehab facility in Florida. The 90-minute guided tours walk you through the whole process — the current patients, the surgical suite, the release videos. It's genuinely well done and never preachy, which is exactly why it lands.

Book in advance. They run a limited number of tours a day and they fill up, especially in season. Allow 90 minutes for the tour plus another 20–30 for the gift shop and outdoor tanks. Book Turtle Hospital tours on Togu →

Snorkeling — The Real Reason to Come Here

Marathon is the base for some of the best snorkeling in the Florida Keys. The water clarity runs consistently better than the Key West sites, and the crowds are thinner:

Sombrero Reef — Protected within the Florida Keys National Marine Sanctuary and marked by the Sombrero Lighthouse. The reef sits in around 15–25 feet of water, with well-established coral heads and a fish density that routinely surprises people who expected the Keys to be worn out. It isn't.

Thunderbolt Wreck — A 188-foot vessel intentionally sunk as an artificial reef off Marathon. It rests in roughly 120 feet of water — that's a scuba dive, not a snorkel, and a popular one for certified divers who want a wreck with heavy coral growth and resident goliath grouper. Snorkelers are better served staying on the shallower reef sites nearby.

Marathon operators tend to run smaller, more personal trips than the big Key West boats. Look for Captain Hook's or Solé Watersports — both run small-group trips out to the less-visited sites. Find Marathon snorkeling tours on Togu →

Bahia Honda State Park — The Beach

Bahia Honda is consistently rated one of the best beaches in the Florida Keys — and by a wide margin, the best beach between Key West and Key Largo. The water is clear, the sand is clean, and the state park has the facilities the other Keys beaches lack.

The main beaches: Calusa Beach (the sheltered cove near the old bridge, calm water, best for families and easy snorkeling from shore), Loggerhead Beach (the long ocean-side stretch with the classic old-bridge backdrop), and Sandspur Beach (the widest sand, quieter, worth the extra walk). The nature trail is worth a short loop through the tropical hammock, with good birding along the way.

There's a small entrance fee (roughly $5/vehicle). Arrive before 11am on weekends in season for a parking spot. After noon the lot fills and they turn people away.

Where to Eat

Keys Fisheries — On the waterfront, famous for its sunset views and its lobster bisque. The menu is seafood-forward and well executed — Key West-style without the tourist-trap feel. Order the lobster bisque and whatever's freshest that day.

Burdines Waterfront — Across from Keys Fisheries, also on the water. Better for casual lunch (burgers, sandwiches, fish tacos) with good water views. The outdoor seating catches the breeze, and it's easy with kids.

Sparky's Landing — On the water at Faro Blanco, a local favorite for fresh fish done simply and a rum drink at the bar. It's the kind of open-air, boats-out-front spot Marathon does best. Order the catch of the day.

Lazy Days South — If you want something more substantial in the evening, Lazy Days South has been a Marathon fixture for years, with a seafood-heavy menu that works for families and couples alike. The oceanfront view doesn't hurt.

Getting There

Drive north from Key West on US-1 (the Overseas Highway). The route is well-marked and hugs the water most of the way. You'll cross the Seven Mile Bridge — one of the most photographed bridges in the Florida Keys, built in the 1980s to replace the original "old seven mile bridge," which now runs alongside it and is open to pedestrians and cyclists. Pull off on the west side for the classic photo angle.

The whole Overseas Highway stretch between Key West and Marathon is scenic and worth taking slowly. Stop at the pull-offs — the views across the bay are legitimately beautiful.

What can you do in Marathon in one day?

Drive up from Key West (about 50 minutes), stop at the Turtle Hospital (book ahead, 90-minute tour), snorkel Sombrero Reef in the late morning, have lunch at Keys Fisheries or Burdines Waterfront, spend the afternoon at Bahia Honda State Park beach, drive back. A full day, but it doesn't feel rushed if you start by 9am. Alternatively, split between Turtle Hospital and Bahia Honda — better with kids.
