Amazing stay
Reviewed 4 hours ago

Tranquility Bay definitely lives up to its name, so relaxing. Enjoyed our time at the pool. Especially enjoyed relaxing at the Tiki Bar sipping a delicious cocktail while watching a beautiful sunset. Wonderful dinner at the Butterfly Cafe, make sure to leave room for a slice of their Key Lime pie.

Everything about this place screams excellence! The General Manager Bob and his staff really put their heart into everything here. The grounds are impeccable, rooms immaculate, and the front desk staff were all so helpful. Don’t miss the tiki bar for the sunset and the restaurant, Butterfly Cafe - WOW!

#1 Resort in the Keys

Hands down best resort in the Florida Keys. Nestled off of the highway one Marathon, Tranquility Bay always offers the best service and amenities that you will find anywhere south of the mainland. Amazing views from the balcony, phenomenal food and access to anything you would need while on vacation

A wonderful slice of heaven

Huge villas with truly stunning views. Make sure you choose a waterfront villa. There is a lovely calm swimming beach and a good size pool. We did not eat on the property as there is a large fridge and reasonable kitchen facilities so we had breakfast and lunch in the villa and dined out in Marathon in the evening. There is very little to do in Marathon but a visit to the Turtle Hospital is worth doing and there are a few really good places to eat. They don’t look like much but food is delicious.

I would definitely return to Marathon for the wonderful views and also their resident iguanas - we named the two big ones Brexit and Big Boy!

One criticism is that the pillows are really awful.
