If you choose one of the itineraries to Alonissos, don’t miss the opportunity to visit the old capital of the island, an architectural jewel full of narrow labyrinthine streets and stone houses with flower-filled balconies. The village’s best-known landmark is the medieval castle, which has magnificent views of the Aegean, particularly at sunset.
The Museum of History and Folklore
This unique museum in the port of Patitiri provides a unique window into the history and traditions of the island through various everyday objects. Part of its collection sheds light on the activities of the pirates that roamed these parts from the 16th to the 18th century, and includes exhibits from their ships.
This coastal village with a picturesque fjord-like harbour is one of the prettiest places on Alonissos. Surrounded by dense pine forests and olive groves, it offers unique nature walks, and is also a good spot from which to explore the surrounding islands by boat. There is a diving centre here, as well as the Centre for the Treatment and Rehabilitation of the Mediterranean Monk Seal (Mom).
Alonissos Underwater Museum
The first museum of its kind in Greece opened in the summer of 2020 and showcases the underwater wealth of the ancient shipwrecks around Alonissos. The first archaeological site that divers can explore, a ship that sank while carrying amphoras off the islet of Peristera, is one of the most famous wrecks of classical antiquity. There will also be an Information Centre in Alonissos Town, where visitors will be able to go on a virtual dive using augmented reality technology.
The National Marine Park of Alonissos
One of the most important natural habitats in Europe, this dazzling aquatic ecosystem is home to rare flora and fauna such as the Mediterranean monk seal, dolphins, coral, and other types of marine life. The park covers Alonissos, the unpopulated islands of Peristera, Kyra Panagia, Psathoura, Piperi, Skantzoura and Gioura, and 22 rocky islets. The public areas of the park can be used for swimming, free diving, or wildlife observation.
Built on the edge of a cliff and surrounded by gorgeous pine forests, the 13th-century twin Byzantine chapels of Agioi Anargyroi (the Holy Unmercenaries) has fantastic views of the sea. The tree-lined path that leads here from Alonissos Town is one of the island’s most picturesque walks.
Kyra Panagia (or Pelagonisi)
Ancient Alonissos developed and flourished on this nearby deserted island. Today, visitors can tour important cultural monuments such as the historic 12th-century monastery, and the restored flour mill and oil press, or swim at the exotic beaches of Saint Peter’s and Planitis.
The Blue Cave
One of the most impressive – and oft-photographed – natural wonders of Alonissos, this dazzling sea cave near the island of Peristera is a shimmering aquatic spectacle in every shade of turquoise, with extraordinary sculptural stalactites on the ceiling.
