Walk the seafloor in a pressurized helmet at Coral World's legendary Sea Trek, hand-feeding tropical fish without getting your hair wet. A bucket-list underwater encounter unlike any snorkel or scuba dive.
What to expect
After a thorough briefing from a Coral World marine biologist, you descend a submerged staircase wearing a pressurized viewing helmet — no certification, no mask, no mouthpiece required. The seabed feels otherworldly as sergeant majors, parrotfish, and the occasional sea turtle glide past. Back at the surface, the park's open-air aquariums, shark lagoon, and stingray touch pool fill another hour or two beautifully. The setting at Coki Point, flanked by natural reef, is stunning.
Good to know
Coral World Ocean Park is located at Coki Point, roughly 20–25 minutes by taxi from the cruise piers (approx. USD 10–12 per person). Sea Trek sessions are limited to 8 guests and run on a fixed schedule — pre-book directly at coralworldvi.com well before your cruise date. Participants must be at least 8 years old and under 300 lbs. Confirm all-aboard time; allow 30 minutes for the return taxi.
