Patmos is one of the legendary must-see islands in the Dodecanese. This is where Saint John resided, presumed author of the last book in the Bible. The cave of the Apocalypse and the Saint John Monastery are dedicated to him. These sites, which are listed by UNESCO as World Heritage, are located at the top of a hillside planted with vines and orchards. On the shore, the crystalline coves of Kambos and Lampi offer absolutely gorgeous swimming areas.
