Patmos Essentials

Patmos is centered around the UNESCO-listed Monastery of Saint John the Theologian, founded in 1088, and the Cave of the Apocalypse, where tradition says the Book of Revelation was written. The island's capital, Chora, features fortified 17th-century mansions like Simantiri and Nikolaidis. Beyond its religious heritage, the landscape includes diverse coastlines ranging from the fine sands of Psili Ammos to the volcanic rock formations of Petra Beach and the rare multi-colored pebbles of Lampi Beach.

Best Beaches

Patmos offers a diverse coastline ranging from the organized, shallow waters of Kampos to the secluded dunes of Psili Ammos, accessible only by boat or trail. Visitors can explore the rare volcanic pebbles of Lampi, the iconic Kalikatsou rock formation at Petra, or the calm, sheltered bay of Grikos. Most beaches feature natural shade from tamarisk trees and crystal-clear Aegean waters, providing a mix of pebble-lined shores and fine golden sand.
