Looking for tropical vibes, turquoise water, and a laid-back island feel? I always find myself heading to Marathon when I want a break that feels like a true escape. Located right in the heart of the Florida Keys, it’s got everything you’d expect—boating, fishing, marine life, and sunsets that make you stop and just breathe. If you love snorkeling, fresh seafood, or just relaxing by the water, you’ll love how easy it is to unwind here.

Best Time to Visit

From my experience, the best time to go is December to May. That’s when the weather is perfect—warm days, low humidity, and plenty of sunshine for all your water adventures. I’ve gone in the summer too when it’s quieter and more budget-friendly. Just make sure you keep an eye on the weather during hurricane season (June–November)—I always do if I’m planning a trip that time of year.

How to Get There

By Car: I usually drive down the Overseas Highway (US-1)—it’s one of the most scenic drives I’ve ever taken. Marathon is about an hour from Key West and two from Miami, and the views along the way are amazing.
By Air: If you’re flying in, I suggest Key West International Airport (EYW) for convenience or Miami (MIA) if you don’t mind the drive. Marathon also has a small airport (MTH), which I’ve used when traveling with friends who fly private or on smaller aircraft.
By Shuttle: I’ve taken the Florida Keys Express before—super easy and relaxing if you don’t want to drive. It’s a great option from Miami or Fort Lauderdale.

Where to Stay

Isla Bella Beach Resort – I splurged on a stay here once, and it was worth every penny. The rooms are sleek and modern, the pools are dreamy, and you’ve got everything from a spa to paddleboarding right on site.
Tranquility Bay Beachfront Resort – If you’re traveling with family, I really recommend this place. The villas are spacious, the beach is calm, and the gardens feel like your own tropical oasis.
Captain Pip’s Marina & Hideaway – When I want something more low-key and budget-friendly, I book here. You can rent a boat, take a dip in the pool, and be just minutes from the iconic Seven Mile Bridge.

Must-see if you are a first-time visitor:

Sombrero Beach – This beach is my go-to for a relaxing day. You’ll love the soft sand and clear, gentle waters—it’s perfect for families or just kicking back under a palm tree with a book.
The Turtle Hospital – I can’t say enough about this place. I took the tour and left totally inspired. You’ll get to see rescued sea turtles up close and learn how they’re cared for—it’s both educational and heartwarming.
Crane Point Hammock – I found this nature preserve kind of by accident, and I’m so glad I did. The trails are peaceful, the wildlife is plentiful, and the history adds a meaningful layer to your visit.
Seven Mile Bridge – You haven’t truly been to the Keys until you’ve seen this bridge. I love walking the Old Seven Mile pedestrian section for the views. Bring your camera—you’ll thank me later.
