Explore Sint Maarten

A tiny in the Caribbean Sea, east of Puerto Rico, is split into the Dutch and French side. St Maarten, which is the Dutch portion of the island, is the focus of this article. It’s the perfect island getaway, and offers pristine, warm diving all year round thanks to its tropical climate. 

There are around 17 dive sites around the south and southeast sides of the island. Sites usually don’t exceed 18 meters (60 feet), meaning diving is easy and perfect for beginners. Tourism isn’t bustling, so it’s great for those that enjoy uncrowded dive sites, even in the high season. Sites include beautiful reefs, lots of wrecks and encrusted rocky spots explore. With around shipwrecks to discover, wreck lovers will be kept very busy. 

Many of the exceptional reefs around St Maarten are rocky structures covered in coral and sponges. Volcanic activity created a lot of the rock formations underwater, which are now teeming with colorful life. Some older reefs suffered hurricane damage, however, they’ve shown great recovery in recent years with new coral taking over the old. 

With sufficient dive centers and dive resorts to choose from in this small island, there’s plenty of availability. Furthermore, some operators travel by boat to nearby islands, like Anguilla, St Barts and Saba. A few liveaboards visit the island, though not many actually depart from it. 

Furthermore, it’s a great place to take an open water certification, or for more advanced dive courses, a wreck specialty would be suitable thanks to abundant shipwrecks here.

Dive Activity

Diving in Sint Maarten

The majority of dive sites here are colorful reefs and wrecks with some breathtaking topography thrown into the mix. Boat diving is the most common practice, though there are a few shore diving opportunities at shallow reef sites. 

The beautiful reefs all around the island are normally shallow and very easy with mild to zero current, promising a relaxing dive for divers of all levels of experience. 

For shipwreck enthusiasts, there are around ten wrecks to explore, and are all taken over by nature, encrusted by corals and sponges and home to an array of tropical fish species. The most famous wreck is the HMS Proselyte, which sank in 1801 and is now located in the Proselyte Reef.
