Aquarium Marin

The Aquarium Marin de Trégastel is one of Brittany's most distinctive marine attractions — it's built directly into the iconic pink granite boulders, with the rock formations actually incorporated into the tanks themselves. You'll find local shore life up close: fish, crabs, and coastal species native to this stretch of the Atlantic. Year-round events keep things lively, from guided tours and workshops to exhibitions exploring tidal phenomena.
