Snorkeling Saint Barthelemy | A Guide to the Best Spots

A dozen good snorkeling spots all around the island

St Barthélemy is a French territory laying southeast of St Martin and Anguilla, north of the Lesser Antilles. It is a small archipelago comprised of only 10 square miles of main island and about 25 smaller islands, islets and rocks.

If you stay in Gustavia, St Barts main city, you’ll find decent snorkeling in popular Shell Beach, just a few hundred meters from the marina. One mile north to Gustavia is Corossol, another nice beach with fair snorkeling around the rocks enclosing the small bay.

Gouverneur Beach, a two mile ride from the city, and located near the southernmost tip of the island, is also a fine option if you are looking for a snorkeling spot in Gustavia area.

To find more exciting snorkeling, head to St Barthélemy Natural Reserve, a protected area covering 1200 hectares of marine environments in 5 sectors of the territory, established in 1996. Colombier Beach, at the northwestern tip of the island, is one of St Barts most popular snorkeling spots.

Only reachable by boat or by a 20-minutes’ walk from Flamands Beach, Anse de Colombier is a great place to spot green sea turtles grazing in the bay’s seagrass meadows. Stingray, shark sucker and barracuda are also easy to spot there.

Snorkeling with sea turtles at Anse de Colombier, St Barts — Colombier Beach, at the western tip of St Barts, is one of the best snorkeling spots on the island to spot sea turtles.

Grand-Cul-de-Sac area, on the eastern coast of St Barthélemy, is also a great option for snorkeling in the reserve. This large bay comprises four smaller coves: Anse de Petit-Cul-de-Sac (considered the best snorkeling spot here), but also Anse de Grand Cul-de-Sac, Anse Marigot and Anse Maréchal. These sites give the opportunity to spot green sea turtles, but also a nice variety of fish and corals in the reef areas.

Snorkeling tours can be organized in Grand-Cul-de-Sac bay, and allow snorkelers to reach the best reef areas, which are located a distance from the shore. Outside the marine reserve, Lorient, on the island’s north coast, is a renowned snorkeling spot, but be very careful there, as in this bay you will encounter lots of waves.

The islets surrounding St Barthelemy’s main island are also great places for exploring the underwater world. Fourchue Island, a 5 miles boat ride from Gustavia marina, is part of the marine reserve and boasts great snorkeling. There, you’ll swim with sea turtles and a whole host of tropical fish in a sheltered rocky bay. You can reach the island with boat tours or with your own boat (managed mooring area).

If you are planning a snorkeling trip to St Barts or anywhere else in the Caribbean, we recommend the excellent Reef Fish Identification: Florida Caribbean Bahamas (also available in ebook), the reference guide to ID the fish you will encounter snorkeling the island.
