The Grotte du Sdragonatu or S’Dragulinu (Dragons cave) is visited by boat from Bonifacio. This huge sea cave is entered through a narrow and low passage, which allows the boats to enter only during good weather conditions with calm sea. The cave is a single huge chamber with a hole in the roof, resembling the contours of the island Corsica on a map. It is also known as Gouffre de la Grotte de Sdragonatu (Pothole of the Dragons Cave). The karst cave has many but rather small speleothems at the walls. The whole tour is rather nice, but because of the boat trip, the contrast of blue sky and blue water with the dark cave and the thrill to enter the cave through a narrow passage. The Sdragonatu grotto is said to be the most visited site in Corsica.
This cave is open without restrictions and for free. As it is located at the sea it may be reached by boat or kajak. Boat Torus are offered by various operator, we have listed one of them. The tours of Guichet Thalassa start at the harbour of Bonifacio, turns west after leaving the harbour. The first stop is the Grotte du Sdragonatu which is entered, then it goes to Cala de Paraguana. Back at the harbour entrance it enters the Grotte de Saint-Antoine, then it follows the southern coast of the Bonifacio peninsula to the rock formations Grain de Sable. The tour takes an hour.
We have read that the Grotte du Sdragonatu is currently closed, as far as we understand because of rockfall. Such events are rather common, over-reaction by officials also. If you plan a visit you should ask the tourist info for up-to-date information.
