Alonissos National Marine Park – A Hidden Treasure of the Aegean

The Alonissos and Northern Sporades National Marine Park is the first marine park established in Greece and the largest protected marine area in the Mediterranean. This natural paradise combines rich marine biodiversity, breathtaking landscapes, and immense ecological value.

The park is home to the endangered Mediterranean monk seal (Monachus monachus), rare bird species, dolphins, and underwater archaeological sites. It stretches around Alonissos and includes remote islets such as Peristera, Kyra Panagia, Piperi, and others.

Visitors can enjoy boat excursions, diving, snorkeling, or simply relax on secluded beaches only accessible within the park. It’s a truly immersive experience that brings together nature, conservation, and the authenticity of the Greek islands.

Alonissos is the perfect base for exploring the Marine Park, offering peaceful accommodation surrounded by pristine natural beauty — ideal for travelers seeking serenity and connection with nature.
