Anchorage on the Aven river between Port-Manec'h and Rosbras, southern Finistère. Mud bottom, good holding.

Guide

Approach and anchoring

Enter the Aven from the sea at Port-Manec'h, 0.5 NM south. The ria is navigable at all tides for most keelboats up to Rosbras. Keep to the channel, banks dry on spring lows. Currents run with the tide, noticeable on the ebb. Anchoring in the ria is awkward, with mooring ground-chains on the bottom and a strong current that calls for a wide swinging circle; do not anchor in the fairway, which carries traffic.

Practical

Visitor buoys are managed by the SNSM at Port-Manec'h and are a better bet than dropping the hook in the ria. Rosbras has a small pontoon 0.7 NM upriver.

Ashore

Pont-Aven sits further up the river. The town has kept the painters' trail associated with Paul Gauguin and the School of Pont-Aven of the late 19th century. Coastal footpath GR 34 follows the ria banks.
