About the Hotel

Take time away from it all in a place like no other: a beachfront haven where you can do it all — or nothing at all. Grab a kayak or a nap, read a book or a menu, work on your tan or your second piña colada.

Tranquility Bay is a place like no other, apart from the crowds. Nestled in the heart of the Florida Keys’ palm-lined paradise, in warm and welcoming Marathon, you’ll find a tropical oasis that’s easy to get to, but hard to leave. Because here you’ll make the memories that matter. Wake up to the glistening waters of the Gulf of Mexico. Stay in a private, standalone beach house right on the ocean or surround yourself in the tropical sanctuary of more intimate garden guest rooms. With no hallways, three pools, onsite watersports and plenty of room to just space out--you can do everything to nothing at all. At the end of the day, let powder-soft sand sift through your sun-kissed toes as you relax on a 2.5-acre private beach. Relax,*sigh*… you’ve arrived.

Reviews for Tranquility Bay Beachfront Resort

Spectacular Beachfront

TripAdvisor Traveler Review Rating Reviewed 2 days ago

Spent my birthday weekend at Tranquility Bay and it was a wonderful getaway! The food at both the Tiki Bar and Butterfly Café was outstanding — fresh, flavorful, and beautifully presented. The staff was attentive, friendly, and really went above and beyond to make our stay enjoyable. We stayed in a 3-bedroom, 2.5-bath unit right on the water, which was the perfect setup for our family of five. The space was bright, airy, and you can't beat the convenience of being steps from the beach. As a Florida resident, I’m used to the occasional insect, but we did notice more small roaches than expected. Also, there were a few minor maintenance issues in the master shower that could use attention. Despite these small hiccups, we thoroughly enjoyed our stay and are already looking forward to coming back!

3 bedroom Villa perfect for family or friends. We are a family of 6, minor children, grandma and husband and wife. Beautiful, large, full kitchen and balconies off every room. Kayaked and jetskiied two days...had a blast. Craig was great at the Watersports. Tiki Bar delicious and front lobby very nice. Gulf side was very nice. White sands. We will return. Thanks

Very Relaxing, Great Staff & Accommodations

TripAdvisor Traveler Review Rating Reviewed 2 weeks ago

We really enjoyed our week at Tranquility Bay. It's a very chill and quiet place, which was just what our family needed. Excellent location close to tons of restaurants and enough to do. We stayed in a 3 BR waterfront villa with our 20 and 17 y/o daughters and it was a perfect layout for everyone to have their own space. We really enjoyed both the Butterfly Cafe and TJ's Tiki Bar. Staff is super friendly and really helped us to just unwind and relax. Hoping we can return for another trip soon.

I’m happy I chose this resort to spend a weekend with my family. As the name states “tranquility” was all over. Not a loud noise, except for my toddler and 7 month old…. Sorry guys lol. But, everything was excellent except the pack and play. I would suggest adding a mattress because putting a baby to sleep in a hard surface is just sad. I tried putting folded blankets I brought from home, however, it was still hard. Placed the baby to sleep me with me the following night and I just didn’t rest. Aside from this small complaint, everything else was clean, kitchen was fully equipped with pts and pans, salt and pepper, glassware, cutlery, cutting boards, microwave, kettle, oven, fridge, dishwasher, washer and dryer. We would definitely return.

Family Vacation 2025

Tranquility Bay was so beautiful. The villa we stayed in was perfect. The grounds were captivating and something out of a picture book. The bed in the Master bedroom was so comfortable and the sheets and pillows were so soft. The view from our room was breathtaking. The other rooms were nice. The couch in the living room was a pullout couch, but ours was old and did not work. I think if that was updated to a more comfortable functional pull out the sleeping arrangements would’ve been a little bit better since we traveled with our adult children. The twin beds in the one room we’re just a little bit small for two adult children. Everyone at the resort was always trying to make sure we were taken care of and had everything we needed. If we didn’t have something we could text and they would bring it over asap. Super great service! Definitely would stay there again!
