Île Tristan - crossing with guided tour

Île Tristan is not a place to visit, but a place to experience. After a short crossing, discover a world apart: wild moors, an ancient orchard, an exotic garden and a fascinating history. Between pirates, artists and unspoilt nature, explore this jewel in the bay of Douarnenez on an immersive guided tour, far from the noise of the city.

Duration: 2h00, crossing included - 20 people max - pets not allowed

The hidden face of Ile Tristan - boat tour

From the sea, the island reveals a different face. Get up close to cliffs, rocks, hidden gardens and unspoilt landscapes on a guided tour. A short, intimate and immersive tour to discover the island and the bay in a different way.

Douarnenez by the sea - the town of three ports
