About Illes Medes Marine Reserve

 

The Illes Medes Marine Reserve consists of a small archipelago of seven islets located near the town of L'Estartit in Catalonia, Spain. Established in 1983, it was the first marine reserve in Catalonia and one of the earliest in the Mediterranean Sea. The reserve covers approximately 0.55 square kilometers (136 acres) of marine area surrounding the rocky islands, featuring underwater caves, cliffs, and sandy bottoms. It is famous for its exceptionally rich marine biodiversity, including abundant fish species, dense populations of gorgonians, and Posidonia oceanica seagrass meadows, which are vital habitats for marine life. The reserve serves as a sanctuary for endangered species such as groupers, moray eels, and octopuses, and serves as a living laboratory for marine conservation.

Historically, the islands have served as natural watchpoints and refuge spots, and today they are a cornerstone for regional marine protection and ecotourism. Recreational activities in the reserve focus mainly on scuba diving and snorkeling, with numerous dive centers in L’Estartit offering guided tours. Kayaking around the islands is popular as well, providing visitors the chance to explore the rugged coastline above water. Fishing is strictly regulated or banned within the reserve to protect its fragile ecosystems. The combination of clear waters, abundant marine life, and easy accessibility make Illes Medes a captivating destination for nature lovers, photographers, and researchers alike.
