Northern Sporades Marine Park is a protected marine area in the Aegean Sea known for its rich biodiversity, crystal-clear waters, and vital role in preserving endangered marine species. It offers exceptional opportunities for snorkeling, diving, and wildlife observation.
Northern Sporades Marine Park, established in 1992, encompasses the coastal waters around the Northern Sporades archipelago in the Aegean Sea, including key islands such as Alonissos, Skopelos, and Skiathos. The park covers a significant area of approximately 2,260 square kilometers, protecting a diverse ecosystem that includes Posidonia oceanica seagrass beds, rocky reefs, and open waters. It plays a critical role in the conservation of the Mediterranean monk seal (Monachus monachus), one of the world’s most endangered marine mammals, which uses the park's secluded caves and islets as breeding grounds. The marine park also shelters numerous fish species, dolphins, sea turtles, and various seabirds, contributing to one of the richest marine habitats in Greece. Recreational activities focus on water-based experiences such as scuba diving and snorkeling that allow visitors to explore underwater caves, reefs, and abundant marine life. On the islands themselves, visitors can enjoy hiking trails with scenic coastal views, traditional villages, and archaeological sites. The park's management enforces strict regulations to balance conservation with tourism, including controlled anchoring zones and restrictions on fishing, ensuring the park’s habitats remain vibrant. The relative seclusion of some islands makes the area particularly appealing for nature lovers and those seeking peaceful encounters with pristine Mediterranean marine environments. Overall, Northern Sporades Marine Park is a vital sanctuary for wildlife and an outstanding destination for exploring Greece's marine natural heritage.
