Alonissos Island Greece, located in the Sporades archipelago, is the third-largest island in the group. It lies northeast of mainland Greece and offers a peaceful alternative to more crowded destinations.
The island stands out for its clean environment and rich marine life. Most importantly, it hosts the National Marine Park of Alonissos and Northern Sporades, the first marine park in Greece. This protected area supports rare species, including the endangered Mediterranean monk seal.
In addition to its ecological value, Alonissos features many stunning beaches. Agios Dimitrios draws attention with its clear turquoise water and unique curve. Leftos Gialos offers a tranquil setting with pine-covered hills around its shore. Meanwhile, Kokkinokastro stands out for its red cliffs and nearby ancient ruins.
The island also presents charming villages and cultural sites. Patitiri, the main port and town, features shops, seaside cafés, and the island’s folklore museum. Although an earthquake in 1965 damaged the area, locals restored it with care.
In summary, Alonissos Island Greece offers a rare combination of natural beauty, ecological importance, and authentic Greek culture.
