About Isabella reef
Isabella reef is a deeper Sint Maarten reef built around barrel sponges, gorgonians and the remains of a small wreck. It suits experienced divers who want a long, multi-level boat dive with a proper offshore feel rather than a shallow sightseeing stop. The site is best run with a local operator and a calm, controlled ascent, because the reef sits out in deeper water and the marine-park rules apply. Expect jacks, stingrays, garden eels, morays, lobsters and hawksbill turtles around the sponges and overhangs.
