Isla Bella Beach Resort & Spa – Florida Keys Overview
You know what, Isla Bella Beach Resort & Spa – Florida Keys is one of those places that actually lives up to the hype – and honestly, that’s saying something in Marathon. This 5-star resort sits right on the water at mile marker 47, and I mean literally right on the water (you can hear the waves from most rooms, which is either perfect or slightly distracting if you’re a light sleeper).
The property itself is gorgeous – think modern Florida Keys architecture without the tacky tourist trap vibe you get at some places down here. Each room has this clean, beachy feel with floor-to-ceiling windows that actually open, which is rarer than you’d think these days. The suites and apartments are spacious, and if you spring for one with a kitchenette, you’ll appreciate having real counter space and a proper fridge – perfect for storing those key lime treats you’ll inevitably buy at the local spots. Staff here is genuinely friendly without being overly rehearsed, and check-in was smooth even during what seemed like a busy weekend.
Well, let’s talk about the good stuff – the spa is absolutely worth it, especially if you book treatments in the late afternoon when it’s quieter. The hotel restaurant serves solid food (the grouper is fantastic), though I’d honestly recommend driving a few minutes to some of the local joints on Overseas Highway for a more authentic Keys experience. Parking is included and there’s plenty of it, which is a relief since you’ll definitely want a car to explore – Sombrero Beach is just a short drive north and it’s one of the best beaches in the middle Keys. The resort’s own beach area is nice but can get crowded, and the sand isn’t quite as soft as you might expect (more packed coral than powdery white). Mornings are absolutely perfect here though – grab coffee and walk the grounds before 8 AM when it’s still cool and quiet. The only real downside? It’s pricey, even for the Keys, and the resort fee adds up quickly if you’re not careful about what services you actually use.
Guest Reviews
What a beautiful place, stayed before, had to come back
We stayed for 2 nights. The property feels large and spacious, with plenty of places to relax, do sports and enjoy the sun. The beach is beautiful and quiet. A good programme with variety of activities and sports. I felt very relaxed and happy there
The resort pool was very nice.
Being greeted by Lydda who was extremely welcoming and informative
Overwhelming! In all my years, I’ve never stayed at a place so nice. The room was phenomenal. The views were spectacular. The staff were excellent. A shout out to Justin. He started out our stay on a high note.

Spacious, clean and well maintained.
Beautiful resort on its own coastline, with lots of activities and good restaurant options. We did paddle boarding (including sharks and manatees), parasailing, jetski in just a couple of nights, as well as enjoying the pool.
