Descend in a real 48-passenger submarine to over 130 feet — deeper than any scuba diver on a recreational dive — and watch the lights of a coral reef and a sunken wreck slide past your own porthole, no swimming, no getting wet. It is one of only a handful of places on the planet where an ordinary traveler can do this, and the sensation of the sub tilting down into the blue is unlike anything a snorkel or glass-bottom boat delivers. Pure bucket-list, and ideal for anyone who can't or won't snorkel.
What to expect
You board a surface ferry at the Shallow Draught near the port, ride out to the dive site, then transfer onto the submarine and descend smoothly along the reef wall and a wreck while a pilot narrates the marine life. The cabin is air-conditioned and pressurized — you feel no pressure change. Children love it and it is fully accessible for non-swimmers. You receive a dive certificate at the end.
Good to know
Pre-book a specific departure time online; the sub runs limited daily slots and sells out on heavy cruise days. The departure pier is at the Shallow Draught, a short walk or 5-minute taxi from the cruise terminal — very low all-aboard risk. Minimum height/age limits apply for small children; check when booking. Bring a light layer, as the cabin runs cool.
