The Cove at Three Waters Resort & Marina is a 21-and-up retreat in Islamorada, Florida. You can spend the morning by its adults-only pool, walk over to Mangrove Beach, and stop at Hideaway for a smoothie or lunch by the water.
The Cove is part of a larger waterfront resort that welcomes families. Guests can explore the rest of the property, including Kokomo, where you can order a drink without getting out of the shared pool.
Start with a beach chair at Mangrove Beach, then see where the afternoon takes you. A swim, a bite by the pool, and an evening by the firepit are all within walking distance.
Every Guest Here Has Officially Outgrown The Kiddie Pool
Twenty-one candles on a birthday cake is the real entry ticket. The Cove at Three Waters Resort & Marina welcomes only guests 21 and older, and that rule is firm at check-in.
The setup is a resort within a resort. The Cove sits inside the larger Three Waters Resort & Marina, which opened in October 2024.
Your section gets its own pool, beach, restaurant, and evening firepit. Nobody under 21 is booking a room in this part of the property.
That doesn’t mean you’re stuck in a bubble, though. Cove guests can roam the entire bigger resort, from its restaurants to its other pools and beaches.
I like this arrangement because it removes a classic vacation headache. You get calm when you want calm, and a lively scene when you feel social.
Couples planning a honeymoon or anniversary will find the math pretty easy. Friends on a group trip get a break from shrieking pool games too.
Booking tip: make sure you reserve a room in The Cove itself. The wider resort welcomes families, so the adults-only perks belong to this specific section.
Stick to that detail and Florida suddenly feels a lot quieter. Your biggest decision becomes pool or beach.
Yes, You Can Order A Snack Without Leaving The Water
Kokomo is the oceanfront swim-up bar at Three Waters Resort & Marina. The pool is shared with families, and it’s a short walk from The Cove.
Kokomo sits at the Kokomo Pool in the wider Three Waters Resort & Marina. A short stroll from your adults-only room gets you there.
The menu leans toward light bites, which makes sense when you’re half underwater. Nobody wants a heavy meal while floating in the sunshine.
Honestly, the whole concept feels a little bit genius. You swim up, place your order, and never bother drying off.
Keep in mind that Kokomo is part of the shared resort. Families can use that pool, so it brings livelier energy than your own quiet corner.
That’s what makes the arrangement so handy. Swing by Kokomo when you want some buzz, then head back to The Cove when you want peace.
Your private section also has Hideaway, its own poolside spot for fresh smoothies and lighter fare. So you’re never far from something cold and refreshing.
Pack waterproof sunscreen and a sun hat. A seat at a swim-up bar under the Keys sun is no place for a sunburn.
Grab A Cabana At The Cove Pool And Call It Your Office
Nobody does a cannonball here, and that’s exactly the point. The Cove pool is reserved for adults, and it sits just steps from the beach.
That short distance changes your whole afternoon. You can swim, cool off, then wander straight onto the sand without planning a trip.
Private cabanas take things up a notch. Each one comes with shade, a couch, and two chaise loungers for some serious lounging.
Food and drink service comes right to you from Hideaway. Cabana reservations at the pool also include a food and beverage credit, which helps the splurge feel smarter.
Cabanas are available on the beach as well. Try the pool one day and the sand the next, then pick a favorite.
My advice? Reserve early if your trip lands on a holiday weekend, since private spots like these are limited by nature.
Bring a good book, a playlist, and a fully charged phone. Shade plus a comfy couch tends to turn a quick break into a long nap.
Honestly, that counts as a perfectly good use of a Florida vacation day. Nobody here is grading your productivity.
This Walk-In Beach Was Made For Lazy Toes
Sand that slopes gently into the water sounds simple, but it’s a lovely perk. The Cove’s private beach has a walk-in shoreline, so you ease into the sea.
No climbing down ladders or hopping off a seawall is needed. You just stroll in until you feel like floating.
The beach belongs to the adults-only section of the resort. That means fewer sandcastle construction zones and more space for your towel.
Want a change of scenery without breaking the 21-and-up rule? Mangrove Beach, elsewhere on the property, is also reserved for guests 21 and older.
Over at Mangrove, you can grab complimentary kayaks and paddleboards. Paddling out from a quiet beach is a nice way to start a morning.
The larger resort adds Mermaid Beach and Paradise Beach to the lineup too. Those are open to all guests, so expect a more family-friendly feel.
I believe the best plan mixes and matches. Spend the morning on your private stretch, then explore the others when curiosity kicks in.
Pack reef-safe sunscreen and water shoes for the trip. The Keys are famous for their marine life, and protecting it is part of the deal.
Lunch At Hideaway Comes With A Side Of Ocean Breeze
Coconut tempura shrimp eaten with your feet near the sand? That’s a regular afternoon at Hideaway, The Cove’s own poolside and beachside restaurant.
The menu focuses on lighter, healthful dishes. You’ll find a Shrimp Bowl, a Caribbean Caesar, and a Local Fish Sandwich among the options.
Craving something heartier after a long swim? A Double Patty Burger is on the menu too, so balance is fully covered.
Fresh smoothies round things out for a sweet, cold pick-me-up. They make a great match for a sunny afternoon by the water.
Hideaway serves lunch and dinner daily, but service wraps up around sunset. Plan your evening meal early, or treat it as an excuse to watch the sky change color.
Hideaway serves lunch and dinner at The Cove. Check with the resort for the day’s closing time and happy hour schedule if you’re planning to stop by later in the afternoon.
Staff also bring Hideaway service to the cabanas at the pool and beach. So you can eat lunch without ever leaving your shady couch.
I like that this spot stays relaxed instead of fancy. Wet hair and flip-flops feel completely at home here.
Wake Up To Water Views From Your Own Balcony
Sixty-three rooms and suites make up The Cove at Three Waters Resort & Marina. That small number keeps this adults-only section feeling personal instead of packed.
Each room is designed for grown-up getaways. Expect a plush king bed, a private balcony, and sweeping views of the water.
The view depends on your room. Some face a calm inlet, while others look out toward the Atlantic Ocean.
Which one should you pick? Inlet views suit people who love quiet mornings, while ocean views are for anyone chasing that big blue horizon.
Some suites add a kitchenette, which is a real bonus on longer stays. You can keep snacks cold, fix a light breakfast, and save restaurant trips for special meals.
Request one when booking if a kitchenette matters to you. Not every room has one, so it’s smart to check ahead.
The balcony might become your favorite spot of the whole trip. Morning coffee simply tastes better with salty air and a water view.
With king beds in a 21-and-up section, the vibe is clearly built for couples. Solo travelers craving quiet will feel right at home too.
Fire Island Is Where Your Evenings Should End
Every night, a firepit flickers to life at the southern tip of The Cove. The spot is called Fire Island, and it’s made for slowing way down.
After a day of sun and saltwater, a glowing fire feels like the right finale. You can sit back, chat, and look up at the stars.
The location adds to the charm. Being at the tip of the section puts you close to the water and away from busier parts of the resort.
I can’t imagine a better place for a quiet conversation. No screens, no schedule, just flames and open sky.
Pack a light layer for evenings, especially during winter months. Keys nights tend to stay mild, but a sea breeze can still feel cool.
Fire Island also pairs nicely with dinner at one of the resort’s restaurants. Eat first, then stroll back to the fire for a peaceful look at the night sky.
Couples will love it, of course. Friends traveling together can make it their nightly meeting point too.
Fun detail: nobody hands you an activity schedule here. That’s kind of the point.
Captains, Kayaks, And A Gym For Overachievers
Boats tie up right at The Cove, which makes heading out on the water ridiculously easy. Guests can arrange trips with seasoned captains through the marina there.
The bigger resort’s full-service marina expands the options. Private charters, fishing trips, and diving adventures can all start from the property.
The mandatory nightly resort fee includes daily bike, kayak, and paddleboard rentals for two guests. The resort lists four hours for bike rentals and three hours for kayak and paddleboard rentals per day.
That makes it easy to explore without spending extra. Paddle along the shoreline in the morning, then bike around in the afternoon.
Some guests skip all that and still want a workout. The Wave Motion Studio, an indoor fitness center inside The Cove, has you covered.
Peloton bikes, rowing machines, and free weights fill the space. Indoor exercise sounds pretty good during a hot Florida afternoon.
I believe the smartest plan uses both worlds. Work out in the morning, then let a captain handle the hard work later.
Book fishing or dive charters ahead during peak season. Popular trips can fill up, and nobody wants to miss a day on the water.
Fun fact: Islamorada proudly calls itself the Sportfishing Capital of the World. Packing a fishing hat suddenly makes sense.
Nine Places To Eat And A Water Taxi Down The Road
Your mailing address for paradise is 84001 Overseas Highway, Islamorada, FL 33036. That puts The Cove right along the famous road that links the Florida Keys.
Cove guests can use all nine dining spots at Three Waters Resort & Marina. Kindler Wood-Fired Fare is the signature restaurant, while Little Limón serves Latin-Asian fusion on a rooftop.
Casual cravings are covered too. Islamorada Pizza Co. handles pizza, Lucky Twist serves soft-serve, and Starbucks keeps mornings moving.
The World Famous Tiki Bar has been part of Islamorada since 1969. Stop by for marina views and live music from 6 to 9 p.m.
Thursday through Sunday.
The Overseas Pool is another option on site. It gives you one more place to cool off between meals.
A scenic water taxi links the resort with its sister properties. Cove guests can also enjoy amenities at Amara Cay Resort and La Siesta Resort & Villas.
That’s a lot of options for one stay. Still, it’s nice knowing your adults-only retreat waits at the end of the day.
Pack comfy sandals and a flexible schedule. Between the restaurants, the water taxi, and The Cove, you might never need your car keys.
