The cave with the chapel in Kamari is the Zoodochos Pigi Cave, an Orthodox cave chapel with a spring of life. It is located at the foot of Ancient Thera, halfway up the mountain path. Reached via a partly steep hiking trail, it offers not only a view of the cave with the spring and the chapel, but also a fantastic view.

Great but steep tour (up to 34%) to the chapel and stalactite cave. Sturdy shoes and trekking poles recommended. The cave is dark, so we recommend a headlamp, as this will illuminate the small cave well for photos.

You should definitely follow the sign. There are several cave churches on Samos but this one is really spectacular

Ruins of a fortress of the Order of St. John. Very steep access. The climb should not be attempted without sturdy shoes. Beautiful view of Agia Agathi beach.
