Excursion Semi-sub exploration tour at Gustavia

Explore the underwater world surrounding St. Barts from the comfort of a semi-submersible boat. The boat remains on the water's surface, while stairs lead you down into the hull, surrounded with glass viewing windows. Take in the scenes without getting wet on this under-the-sea adventure.

Gustavia's harbour, St Barts Marine Park

Walk from the pier to the awaiting semi-submersible submarine and gather on the main deck for a safety briefing. Cruising out of the main harbour, remain top-side or descend into the hull of the sub. As you reach the entrance of Gustavia's harbour, you may see some of the many green turtles known to reside in the area. Pass over the wreck of the 50-feet (15-metre) island freighter Marignan, sunk during the famous hurricane 'Luis' in 1995. On the way to your next stop, the vessel crosses the south-east edge of the St. Barts Marine Park, where the sea is full of colourful coral reefs, gently 'invaded' by troops of striped 'sergeant major' fish.

Returning to the pier along the same route, you can remain below or if you prefer, cruise on the upper deck and watch the beautiful anchored yachts and shores of St. Barts.
