The path of the Pelouse is a beautiful path to appreciate the landscapes of the Oise. Here, a lock dam creates an interesting water feature.

Hello backpackers Completely agree Sam, this little bit is very useful, but we are still missing 500-600 meters to connect the rest of the towpath which goes towards Mery sur Oise, we are obliged to make a little right left, and catch up a parallel path that I suppose you know 😁.
