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

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.

View of Domaine de Trévarez

Highlight • Viewpoint

Finistere is heavily forested and a bit more pristine. We enjoy that.
Here a "château" peeks out of the forest. That is the Domaine de Trévarez, which is still quite a distance away - it is only thanks to the telephoto lens that we can get so close.
