The main cultural attractions of Skiathos are the churches/ monasteries and other memorials of the Byzantine and the Venetian era. The most attractive monasteries are those of Panagia Eikonistria and Panagia Evangelistria, which includes a museum of Greek revolution.

It is worth seeing the castle Bourtzi and the house of Papadiamantis, the awardwinning author of the island. Notables are the Folklore Museum of Skiathos which is housed in the spiritual center as well as the museum of Naval and Cultural Tradition in Bourtzi.

There are daily boat trips to Lalaria beach, with the unique white pebbles and to the Tsougria island with the turquoise waters which enchant visitors.
