Guide

Approach and anchoring

Approach from the Anse de Kerdelan between Île Longue and Île Berder. Strong tidal streams run through the gulf, with slack water around high and low tide, and the current curls through the anchorage and swings boats sharply at the turn. Mud bottom gives good holding, but watch for oyster beds and stakes close by, with old oyster tables and scrap metal on the bottom that can foul an anchor. Any free mooring buoys have little swinging room, so boats can end up close together. Shelter from NW through W to S, open to the E and NE.

Practical

No shore facilities at the anchorage itself. Water, fuel and provisioning at Larmor-Baden 0.9 NM NE or Port Lagaden 0.9 NM NE. Several private mooring buoys in the area, space to anchor clear of them.

Ashore

Larmor-Baden village has a bakery, grocery and restaurants within 15 minutes by tender. Boat trips from Larmor-Baden run to the Cairn of Gavrinis, a Neolithic passage tomb on the neighbouring island of Gavrinis dating to around 3500 BC.
