Nestled in the rocky side of northern Saint-Barthélemy, Colombier Beach (Anse de Colombier) is the most famous snorkeling spot on the island. It offers a beautiful beach and a calm and turquoise sea, well sheltered from the waves. Being protected by a natural reserve, this spot allows to observe a vibrant underwater life. Green sea turtles, stingrays, barracuda and sharksuckers meet here among the sea grass, while a myriad of reef fish takes shelter among the rocks which border the bay.

How to get to Anse Colombier snorkeling spot?

Anse de Colombier is located on the north-western tip of Saint-Barthélemy island. This cove is only accessible by sea or by two hiking trails.

The most enjoyable trail is the one which starts at the end of Anse des Flamands: it runs along Petite Anse, before descending towards Anse de Colombier. Plan a 20 to 30 minutes’ walk to get to the beautiful beach.

Water entrance for snorkeling Anse Colombier

If you go to Anse de Colombier by foot, you can get into the water from the beach. We rather recommend the northern side of the beach (on your right while facing the sea) in order to be closer to the reef areas, which are less frequented by boats.

If your boat moor in the cove, you can enter the water from the boat.

Anse Colombier snorkeling exploration tips

You can snorkel the whole cove, but we recommend the northern area, less frequented by boats, which come in high number to dock in Colombier.

In the middle of the bay, you can find rather deep seagrass beds (↕12-20ft/4-6m), known to be visited by many green sea turtles. We often see them grazing peacefully on the seagrass or resting on the seabed. They are used to the presence of boats and swimmers, and they easily allow people to watch them.

If we go to Colombier especially for sea turtles watching, the protected seagrass of the cove allows you to observe many other species, especially southern stingrays, bar jacks, barracuda, and sharksucker attached to the turtles or swimming alone in the open water.

All along the northern coast of the cove (↕6-12ft/2-4m), the seabed is covered by rocky screes, with few corals. Pay attention to sea urchins, pretty numerous in the area. Here you can watch many species of Caribbean fish: grunts, butterflyfish, French angelfish and sometimes small moray eels, surprised while sliding between the rocks, or lobsters.

Southern stingrays are common on the seagrass.

Since Colombier Beach is part of Saint-Barthélemy Natural Reserve, fishing is prohibited here and, therefore, the underwater life is thriving. Pay attention to the numerous boats which navigate and moor in the cove.
