Also known as Pouars or Port de Plane, this well-protected cove resembles a small port. Left-hand rock, access only possible in calm seas to a small tunnel passing outside the cove between 4 and 8 m. Outside, two rocky peaks at around 12 m and a ridge at 20 m dropping to a maximum of 35 m.

The cave itself is a tunnel that opens at 12 metres, at the bottom of the canyon on the right. If you look up very quickly, you will see a well into which you can climb to come out into the open air, in a basin surrounded by glistening rocks. When the weather is fine, the lighting is magical.
