It is curious to see how the canal passes over the river by a bridge, like the old aqueducts.

Right next door is Rochemontes Castle, a must-see. I couldn't tell you which side of the river it is; it all depends on where you're coming from. There's some serious stuff for those who enjoy it. 😉 Enjoy your walk
