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!

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.

A wide variety of goods were available from a food truck. Unfortunately, the coffee, which had been kept warm, wasn't very good. But the homemade cakes were delicious.
