Natural heritage

The Nature Reserve protects a unique natural heritage of the island of Saint-Bartholomew, we invite everyone to watch ... and respect.


Colombier is located in the extreme west of Saint-Bartholomew. It has a lovely white sand beach lined with vegetation. This is the last beach which is not served by a public road. The only building visible from the beach is the home of billionaire David Rockefeller, origin of the development of a high-end tourism in Saint-Bartholomew.
A small trail brings us to the beach in about twenty minutes from Petite Anse. During this short walk you will encounter animals such as the Couresse of the Band of Anguilla (Alsophis rijgersmaei) a small protected snake and many ameives. In the recesses of the cliff lies a cave that houses a small colony of bats (Molossus molossus). You will find fragrant lilies, purple orchids, and also cacti along path.


The Nature Reserve maintains in Colombier Bay several ecological moorings. They are located near the coast, where the seagrass are the most important.
Seagrass and all the species that live there are protected for damage caused by an anchor. Take your fins, masks and snorkels, the waters teem with life! Maybe you'll have the chance to cross a turtle. Many are feeding in the area.


Fourchue is a small island halfway between Saint-Bartholomew and Sint-Maartin. This is a private land, we can not get there at will. However, the Nature Reserve offers to boaters many anchorages in the bay.


Fourchue has a single beach. Its black sand is made of stone from the island, reduced by the incessant trampling of goats. Introduced by humans, these animals were involved in the destruction of vegetation. There are no more goats, so the vegetation grows again. In april 2011, the Nature Reserve has released a couple of iguanas from Saint-Barthélemy to Fourchue, where the environment becomes favorable again and where there is still no invasive iguanas. This is one of the last places where you encounter the Rubescens cactus (Opuntia rubescens), cactus endemic to the Lesser Antilles.

Fort Carl

The Fort Carl is one of the three forts of Gustavia built during the suedish period, with Forts Gustav and Olav. It is located on a small hill of 29m high. It overlooks Shell Beach and offers a beautiful view of Gustavia, with the construction of a viewing platform by the Nature Reserve.

Fort Carl is a site owned by the Conservatoire du Littoral since 2007, managed by the Nature Reserve. The Nature Reserve conducted a methodical pruning of the site, restored buildings, installed steps and helps revegetate of the summit with local plants only.
Pay attention, downstairs there are few mancenilliers: these trees are dangerous! Fruits, leaves and the trunk contain a milky sap which is highly toxic. Remember their appearance to avoid them, especially in case of rain. This tree is common on sandy shores.
