Step aboard the Key Largo Princess and let the sea reveal its secrets. This 75-foot, Coast Guard–certified glass-bottom vessel glides over the living reefs of John Pennekamp Coral Reef State Park, the nation’s only undersea park. ...
This glass-bottom boat tour out to the Florida Keys reef is a genuinely enjoyable experience, with the crew consistently standing out as a highlight. Reviewers rave about how knowledgeable and enthusiastic the staff are, and the boat itself is well-maintained with a climate-controlled cabin, a sun deck, and a full snack bar onboard. Several guests spotted turtles, manatees, sharks, and plenty of fish, making for memorable moments on the water. It's worth setting realistic expectations about the reef itself. Coral bleaching from warming waters means the underwater scenery isn't as vivid as it once was, and some visitors found the marine life a little sparse depending on the day. The boat travels roughly six miles out, so the majority of the trip is transit time rather than reef viewing. A few guests also noted that popular departure times can feel crowded around the viewing windows. That said, most travelers come away happy, especially those who treat it as a relaxing cruise with a side of reef viewing rather than a deep-dive wildlife experience. The combination of a comfortable boat, genuinely engaging crew, and those stunning turquoise Keys waters makes it a solid choice for a fun few hours on the water.
Great value and fun trip! The water and reefs are beautiful. Very informative guide to explain the reefs. Bar and snacks on board. Air conditioned area by the glass bottom to stay cool on hot days. Nice excursion.
