New cafe just on the way out of Pontivy owned by a very friendly and helpful gentleman with lots of experience and tips. He will soon have a bike repair station too! Top!

Here the origin of the path can be seen: it was an old railway. The old station is well maintained.

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

A great detour to Saint Aignan, the Les Pêcheries de Guerlédan restaurant is very welcoming, with bike parking, a generous meal and welcome. Crossing the village, you can reach the canal a little further on via the lock.

You have to carry the bike to cross the dam, but it's worth the view!
