Sandbars are shallow stretches of soft sand surrounded by clear, calm water. Locals and visitors alike flock to them to swim, float, sip a drink, or just soak up the sun. With a Captain, you’ll skip the stress of navigation and get local insight on where to go, when to go, and how to make the most of your time.
With Boatsetter, it’s as easy as choosing your boat, choosing your day, and showing up. We’ll handle the rest. According to 2025 booking data, 79% of boat rentals in Key West are Captained. That means most travelers choose to leave the driving to a pro so they can sit back and relax.
The Best Sandbars Near Key West
From spacious pontoons to clean center consoles, boat trips start at $340 for a half-day (4-hrs) with Captain included.
Islamorada Sandbar
Known as the “sandbar capital,” Islamorada is lively, social, and perfect for a day of floating with friends. Boats here often come with floating mats, turning the shallow turquoise water into your own private lounge. Locals describe it as a “tailgate on the water”with music, drinks, and a festive vibe where everyone drops anchor side by side.
Marvin Key Sandbar
Pristine and surrounded by mangroves, Marvin Key offers calm, clear water with a more low-key vibe. Many boat rentals come with snorkeling gear, making it an ideal stop for spotting tropical fish parrotfish and yellowtail snapper among the mangroves. It’s the kind of place where adventure meets relaxation, and your group can slip from lounging to snorkeling without missing a beat.
Boca Grande Sandbar
Set against powdery white sand and glowing turquoise water, Boca Grande has a unique charm. Rent a boat with a spacious deck or shaded lounge area and settle in for a picnic or swim. Unlike the social scene of Islamorada, Boca Grande delivers deserted island vibes, it feels like you’ve sailed past the end of civilization to your own private paradise.
Content Keys
Remote and untouched, the Content Keys are where you’ll find wildlife and serenity. A Captained boat tour focused on nature is the best way to explore, expect to spot dolphins, rays, or seabirds in the calm waters. It’s the perfect choice for those who prefer quiet beauty over crowds.
Snipes Keys
With shallow, warm water and a lively atmosphere, Snipes is a favorite for groups who love to mix fun with exploration. Find a boat rental with paddle boards and go gliding across the shallows or venturing a little farther from the boat. It’s where relaxation and play meet in equal measure.
