Chora - Grotto of Negro
The Negro’s Grotto in the area of Vatses, with its astonishing formations of stalactites and stalagmites.
You can reach this place by boat, departing from Chora or the area of Analipsi and landing on the sandy beach of Vatses (the beach is quite steep, with intense wave action).
Then, you have to walk to the cave up on the mountain. The course is quite demanding, especially for beginners.
