The reconstruction is great! But we left some parts in ruins, which preserves the character of an old building.

Yes - a very beautiful lock keeper's house. We were able to take a relaxing break here! Someone has invested a lot of love and time here and turned it into a gem. 💎

The Vélodyssée was an experience for us - a wonderful meandering canal. Constantly changing landscapes. It must have been an odyssey for the boaters - because so many locks in a row - they couldn't move any faster than a pedestrian - if at all. Many locks have obviously been out of service for a long time. Only some in certain areas are still in operation. However, some locks are being reactivated. Whether this has anything to do with the poor water quality and the swamping of the unused parts of the canal - I don't know.

A stretch on the dam before the Trehu Moron dam. The landscape is constantly changing. The canal meanders through the countryside here. I love this landscape, and it's a good mood to drive here.
