Giola is a breathtaking natural pool created in rocks at sea level on the southern coast of Thassos, near Astris. The coastline around the lagoon is covered with white shelf-like rocks, 8 m high in some places, and you can jump from the rocks into the deep pool. Ask for directions from a local, as it is not easy to find. A hike from the road is required to reach Giola, but it is worth it!
