Châteaulin

Highlight • Settlement

Châteaulin is a "bridge town", that is to say that it owes its economic activity and its creation to the last bridge which was located over the Aulne. It is also a strategic city between sea and mountains. It is located near the estuary and the harbor of Brest and also close to the Armorican massif, and also along the Nantes-Brest canal.
Finally, it is a very good place to take a break.

Nice to ride on the cycle paths along the canal. Very quiet and beautiful.

Saint-Algon Lock

Highlight • Structure

Like the many locks on the Nantes-Brest canal, the Saint-Algon lock has long allowed boats to transport goods from one city to another. Today, the lock house is only the breath of a memory of this river period.

Châteaulin Lock House and Canal

Highlight (Segment) • Structure

Apparently, they're in the process of repairing/restoring the locks.
The water level was lowered for this purpose.

This was the case in June 2024 - @Lydie attached a picture showing that the water level is back to normal.
This means that the work on the locks that were repaired is now complete.

Châteauneuf-du-Faou

Highlight • Castle

Bathed by the Alder, the town of Châteauneuf-du-Faou is an ideal stopover on the Nantes-Brest canal. Below, a campsite and a bistro await you. If you want more, you can always tackle the steep climb that brings you downtown. The shops are more numerous there and, on Thursday afternoon, the weekly market is held there.

Nantes to Brest milestone – Finistère

Highlight • Monument

This "milestone" is a beautiful old witness to history.

It would be worth preserving these stones better.

A tour along the Nantes Brest Canal with many locks. A bit steeper at the end but otherwise very flat.
