Key Largo Glass Bottom Boat

Overview

Get the wonders of the ocean at your feet with a two-hour Key Largo Princess glass-bottom boat cruise. You’ll see the underwater world of John Pennekamp Coral Reef State Park, the only undersea park in the United States.

Imagine cruising over the crystal clear waters of Key Largo on a glass bottom boat. It's like looking into a giant aquarium, but better. You're not simply observing, you're a part of the scenic ocean beauty. Bright, tropical fish dart below while colorful coral reefs paint the underwater landscape. This isn't an everyday boat tour, this is an unforgettable experience.

John Pennekamp Coral Reef State Park via glass bottom boat shows you a new side of Key Largo. Gaze down into the pristine waters and find yourself marveling at the stunning marine life that calls the Florida Keys home. What could be more amazing than witnessing a sea turtle gliding gracefully past or spotting an exotic fish you've never seen before? Join us for an adventure that will stay in your memories long after the tour ends.

Hop aboard and enjoy the 45-minute Key Largo cruise out to the reef, sip a cocktail on the sundeck, and enjoy a panoramic offshore view of the Florida Keys. Once you’ve reached the reef your narrator will tell you all about the world below. The viewing window on this glass bottom boat is large enough for everyone to observe the reef simultaneously. See the reef itself, built from many varieties of living coral and teeming with sea fans and sea plumes, and then there's the hundreds of fish of all different colors and sizes. You may even get the chance to spot a ship wreckage.

This Florida cruise will take two-hours in all and is an ideal way to spend a relaxing afternoon. You can also purchase a variety of snacks, soft drinks, and adult beverages such as beer, wine, and mixed drinks onboard.
