The Medes Islands Natural Reserve, located off L'Estartit on the Costa Brava, is one of the most spectacular marine protected areas in the western Mediterranean. With its exceptional biodiversity and fascinating history, this site attracts divers from around the world each year in search of unique underwater landscapes and rare species.
Site History
The Medes Islands, a small archipelago made up of seven islets, were once a strategic location for fishermen and sailors. Used as a military base for centuries due to their geographical position, the islands have gradually seen their military importance decline to become an area of ecological interest. In 1983, they were declared a protected area, and in 1990, they obtained the status of a marine natural park, in order to preserve the richness of its underwater ecosystems.
Thanks to these protective measures, the marine flora and fauna of the Medes Islands have been able to regenerate. Today, the reserve is home to more than 1200 species of animals and plants, making this place an ecological sanctuary of immense importance for Mediterranean biodiversity.
L'Estartit: The Gateway to the Medes Islands.
The small coastal town of L'Estartit, located at the foot of the Montgrí massif, is the ideal starting point for exploring the Medes Islands. Once a fishing village, L'Estartit has transformed over the years into a popular tourist destination, especially for water sports and scuba diving enthusiasts. With its modern port and numerous facilities, L'Estartit offers visitors a warm atmosphere while remaining close to nature.
In addition to diving, the town offers a wide variety of activities, including boat trips around the Medes Islands, hiking in the Montgrí natural park, as well as beautiful beaches lined with pine trees and steep cliffs.
