The sites on the Dutch side of St Maarten are completely different to the dive sites on the French side of the island. There are more wrecks on the Dutch side of the island and the reefs have a higher density of barrel sponges.
The Dutch Marine reserve surrounds many of the sites by the mile marker buoy, in front of Philipsburg inside the Man of War Shoal Marine Park . This is where many of the diving centers that cater to the cruise ships frequent, which is why we always try and pick somewhere less crowded and a little further away. Some of the wrecks on the Dutch side include the Porpoise, the Fuh Sheng, The Gregory, The Bridge, The Roro and the Proselyte.

There are also some lovely reefs, like Crazy Horse and Charlie’s Shoal.
