An island least touched by tourism is Alonissos, the most serene island of the Northern Sporades groups of islands and known for its natural beauty and beaches. It is claimed that the seawater around Alonissos is the cleanest of the Aegean Sea.
The old-world charm of Alonissos provides a tranquil and sleepy atmosphere. The beauty of Alonissos is also due to its dense pine forests that cover a large part of the island. Looking over the Sporades islands is the beautiful little village of Chora.
The National Marine Park of Alonissos is the first Nature Park of Greece established in 1992. The Marine Park includes another six smaller islands and 22 uninhabited islets. In the area of the Marine Park you can swim and take photographs although fishing, hunting and camping are not allowed.
The nearest airport is on Skiathos, and from there you can either get the ferryboat (about 1.5 to 2 hours, or hydrofoil: 1 hour). You can also get a hydrofoil or ferryboat from Volos or Agios Konstantinos.
