About Medes Islands Marine Reserve

 

Located off the Costa Brava coast near the town of L'Estartit in Catalonia, Spain, the Medes Islands Marine Reserve was established in 1990 as one of the first marine protected areas in the Mediterranean Sea. Comprising a small archipelago of seven islets, the reserve encompasses a diverse underwater ecosystem including rocky reefs, seagrass meadows, caves, and sandy bottoms. These habitats support an array of marine life such as groupers, moray eels, sea bream, and rare species like the Mediterranean fan mussel. The reserve's waters attract divers and snorkelers who come to explore its extensive underwater trails, vibrant coral formations, and rich fish populations. Fishing and anchoring are regulated to protect the delicate ecosystems. On land, the islands are largely uninhabited, providing essential nesting sites for seabirds. The reserve serves as a critical research site for marine biology and conservation, demonstrating successful marine resource management. Visitors enjoy boat tours, diving excursions, and paddle sports while appreciating the natural beauty and ecological significance of the area. The Medes Islands offer a unique marine experience showcasing the importance of preserving Mediterranean aquatic biodiversity.
