Private boatyard pontoon on the Crac'h river, a short distance southeast of La Trinité-sur-Mer in southern Brittany.

Guide

Approach and anchoring

Reached via the Crac'h river from the Baie de Quiberon, through the buoyed channel of La Trinité-sur-Mer. Max draught 1,8 m. Strong tidal current in the river on spring tides. Local pilotage advised for first visit.

Practical

Private facility geared to yard works rather than visitor stopovers. For transit berths, use the marina of La Trinité-sur-Mer at 0,8 nm NW. Full shops and restaurants in La Trinité village.

Ashore

Carnac alignments of Neolithic standing stones at about 4 km to the west, a UNESCO tentative list site with thousands of menhirs dating from around 4500 to 3300 BC. Beaches of the Baie de Quiberon along the coast.
