Very nice route, 3/4 of which is in the forest. The few roads used are very quiet. The advantage of this route, if you like, is that it can easily be transformed into a mountain bike route. Just look to the right or left of the cycle path and there is a single track. Have a good trip to all those who wish to take it.
