Guide
Approach and anchoring
Reach Châteaulin by the tidal Aulne from Landévennec, then through the Guily-Glas lock which opens around high water, about 30 minutes after high water Brest. From the lock, 8 km of still water lead to the town quays; the reach shoals, so boats drawing about 1.8 m or more may touch between Port Launay and Châteaulin and should time it close to high water. Mud bottom gives full 360-degree shelter behind the lock. Port Launais lies 1.2 nm NE, Port du Faou 7 nm NW.
Practical
A new pontoon on the right bank below the church now has water and electricity by token from the tourist office, along with new showers. It is small, taking two small yachts, so larger boats lie alongside the quay wall. No fuel. A large supermarket about 150 m away has a laundrette in its car park, with the town centre, bakery and railway station to Brest and Quimper within 500 m.
History
Châteaulin was the salmon capital of Brittany until the 20th century, with the Aulne supplying markets across the region. The town still holds salmon on its coat of arms.
