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.

Great stretch on the bus lane, about 2km long. Ideal because there's almost no motorized traffic. Perfect for pumping the pedals and picking up speed. If you have the wind at your back as a bonus, then you feel like you're growing wings.

It is recommended to take the cycle path because the police have already fined some of my friends who were riding in the bus lane.

Ideal for a coffee break. There's a bar and a pastry shop that makes delicious macarons! There's a water fountain next to the church, a little further on.
