The caldera is not suitable for climbing because of loose volcanic rocks, but on the east side there are three organised climbing fields on the mountain. At Perivolos there is excellent quality limestone that will satisfy fans of the sport. Because it is east-facing climbers choose only the afternoon hours for climbing.
On the beach of Perissa at the edge there rocks chosen for climbing mainly in the morning when they are in the shadows. Finally the uphill route from Kamari leads to the Site of Ancient Thera that is selected for climbing mainly in the afternoon.
