Îlet la Mère Monkey Island (French Guiana)

Weather…

Îlet la Mère is a small, uninhabited island located off the coast of Cayenne, renowned for its rich history and its inquisitive primate residents. During the 19th century, specifically between 1852 and 1875, the island served as a site for part of the French penal colony system, the ruins of which are still visible amidst the dense vegetation today. Now, the island is most famous for its population of squirrel monkeys, which were introduced in the 1980s for research purposes and have since thrived and multiplied across the island. Accessible only by boat, the island features a well-maintained hiking trail that leads visitors past historical remains and scenic coastal viewpoints. It is a popular destination for nature lovers and history enthusiasts alike, offering a unique blend of dark colonial history and wildlife interaction. The island's relative isolation has helped preserve a micro-ecosystem that stands in stark contrast to the mainland. Visitors are encouraged to respect the monkeys' natural environment to ensure the long-term health of the population.
