The island of Groix, 45 minutes from Lorient, is a wild 15 km² island with spectacular cliffs. Its Grands Sables beach is one of the few in France facing the open sea with a convex curve. Groix lobster and bluefin tuna long built the reputation of its fishermen.
The island that fished for tuna
Groix lies 45 minutes by ferry off Lorient: eight kilometres by three, 15 km², a plateau of cliffs and heath with around 2,300 year-round inhabitants. At the end of the nineteenth century it was France's leading tuna port — several hundred boats sailed from Port-Tudy — and the parish church in Le Bourg still has a tuna, not a cockerel, on its steeple. The Écomusée in the old canning factory tells the story.
The geology makes Groix unusual. The island is built of blue glaucophane schist, shot through with garnets, and the east-coast beach of the Grands Sables is one of the very few convex beaches in Europe — it actually bulges out into the sea, and shifts position from year to year. Part of the island is a mineralogical nature reserve, and collecting is forbidden.
The south and west coasts are the wild side: the Trou de l'Enfer, a sea cave open to the sky, the pointe de Pen-Men and its lighthouse, and the tiny harbour of Locmaria. The coastal path runs right round the island in about 25 kilometres.
May to September
The island works from May to September; June and September are the months when the coast path is empty and the light is best. August is busy but never as saturated as Belle-Île. The international film festival, FIFIG, fills Le Bourg at the end of August. The sea is cool — 16 to 18 °C in summer — and the Grands Sables is the sheltered beach for swimming.
Leave the car in Lorient
Ferries run year-round from Lorient's Gare Maritime to Port-Tudy, about 45 minutes, several times a day; in summer there are also sailings from Lomener and Doëlan. Vehicles can be carried but need a reservation and cost a great deal — almost everyone hires a bike at Port-Tudy instead. The island is hilly enough that an electric bike is a reasonable idea.
Le Bourg, a kilometre uphill from the port, is where the shops and most of the restaurants are. Book ahead in summer; accommodation is limited to a few hotels, guesthouses and a campsite. Eat the tuna when it is on the menu, and the local cider.
