Une petite baie qui fait partie de la grande baie de Pont-Mahé. La plage se découvre largement à marée basse et semble prisée des pêcheurs à pied locaux.

Not necessarily the most suitable beach for swimming, but the view of the rocks and the bouchots is worth the trip.

A very beautiful city, both for its iconic port at the foot of the rocks and for the old town and its charming alleys.
