An aquarium installed beneath the pink granite
The Trégastel Aquarium owes its uniqueness entirely to its stone setting. It is located within a series of natural caves formed more than 300 million years ago in the heart of the Granite Chaos. The roof of the first hall alone weighs nearly 5,500 metric tons—a record that impresses visitors.

These caves have served a thousand different purposes before becoming an aquarium. Since the 19th century, they have successively housed a chapel, a residence, an ammunition depot, and then a prehistoric museum. Today, they immerse families in the underwater world of Brittany— a setting found nowhere else on the Côte d’Armor.
A tour through three zones, from the spray to the depths
The Trégastel Aquarium’s exhibition follows the rhythm of the sea, taking visitors through three distinct areas. This educational presentation helps children understand how animals live in relation to the tides. Each area showcases a different habitat and its inhabitants.

Here are the three areas covered during the tour:
- The intertidal zone, located above the high-tide line, is home to intertidal life.
- The intertidal zone, swept by the ebb and flow of the tides, showcases the species that have adapted to this constant ebb and flow.
- The “Zone des Profondeurs,” which is always submerged, is home to fish from the depths off the coast of Brittany.
As you walk past the tanks, you’ll come across seahorses, lobsters, sea bream, sea bass, and starfish. Abalones, anemones, and scallops round out this beautiful showcase of the Channel’s marine life.
The Eternal Father and the View of the Pink Granite Coast
The tour has a lovely surprise in store as you exit the caves. As you climb to the top of the site, you’ll reach the base of the Père Éternel, a statue erected on the rocks in 1869. From up there, the panoramic view of the Pink Granite Coast makes the climb well worth it.
