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.

Don't be surprised if you spot flamingos 🦩 on the banks of the pond. They're still there, despite the park being closed for many years.

The turtle head welcomes you at the end of the hike with its two big, friendly eyes!

Many fishermen along this pond, the starting point of the Drouette. It's a must-see in the area :-)
