About Tranquility Bay Beachfront Hotel and Resort, Marathon

Beachfront resort on Marathon Key with 3 pools

Private beach access

The Tranquility Bay Beachfront Hotel and Resort is located on a private white-sand beach in Marathon. You're a 5-minute walk from the turtle rehabilitation hospital, and less than 2 miles from the start of Seven Mile Bridge, one of the longest bridges in the world.

Snorkeling and diving

You could spend hours exploring Crane Point and Museum of Natural History, a 5-minute drive from the hotel. Less than 2 miles away, snorkeling or diving among colorful tropical fish at Sombrero Bay will brighten your afternoon.

3 outdoor pools

You can get in a workout at the fitness center, or take a dip in your choice of the resort's 3 outdoor pools. After working up your appetite with a stroll on the beach, you can enjoy an evening of fresh local seafood at the Butterfly Café or a cocktail at TJ's Tiki Bar.

Whimsical coastal design

Single-level guestrooms and 2 or 3-bedroom beach houses feature conch-style architecture and handmade furniture with a tropical vibe. In addition to a flat-screen TV, you'll have a mini-fridge and coffeemaker, while some beach houses offer gourmet kitchens.
