Groix Island, a unique archipelago
 

~

Located 14 kilometers off the coast of Morbihan, the island of Groix is the third inhabited island in Brittany. Less frequented than Belle-Île, less well-known than Noirmoutier, it attracts those seeking a complete change of scenery without sacrificing authenticity. Its 2,300 permanent residents, its red schist cliffs, its wild beaches, and its history as a tuna fishing port make it a unique destination—one that Bretons recommend to their trusted friends.

​

From the terrace of the Keruster Lodge, the island of Groix stands out against the horizon on a clear day. It's one of the first things guests notice upon arrival. A day trip to the island is one of the activities that Bastien and Anaëlle highly recommend.

The beaches

The island of Groix boasts 36 beaches and coves. The most famous is the Grands Sables beach: the only convex beach in Europe on the Atlantic coast, its colorful pebbles (schist, rose quartz, amethyst) make it a unique geological site. The other beaches are mainly secluded coves sheltered from the wind.

  • Grands Sables: a unique convex beach, colorful pebbles, ideal for swimming and picnics.

  • Locmaria: wild coast, cliffs, hiking

  • Port-Lay: sandy beach in a sheltered cove, ideal for families with children

  • Moustéro Beach: swimming in calm waters, facing the mainland

​

Hiking and island tour

The island can be explored on foot or by bicycle. The GR340 trail makes a complete circuit in a day (30 km) with panoramic views of the Atlantic from the cliffs of Pen Men. Shorter routes connect Port-Tudy to the nature reserve in 2–3 hours.

  • GR340 complete: 30 km, 1 day, intermediate level

  • Pen Men (western point): lighthouse, view of the mainland and Belle-Île

  • Groix Island Nature Reserve: free access, protected coastal flora

  • Bike rentals are available in Port-Tudy right after you disembark the ferry.

​

History and culture

For over a century, Groix was one of France's largest tuna fishing ports. The island's Ecomuseum recounts this era: models of tuna boats, nets, and testimonies from sailors' families. In Port-Tudy, the tuna warehouses, now converted into galleries and restaurants, have retained their original architecture. A gilded metal tuna sits atop the church steeple—the island's emblem.
