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.

King Francis I died there. In 1804, Napoleon took possession of a castle in poor condition due to the Revolution. He had important work done there. When the monarchy was restored in 1815, Louis XVIII reinvested the castle and undertook some work. More than half of the Presidents of the Republic have stayed there. A true haven of peace, the place is ideal for combining family life and high-level diplomatic meetings, in a relaxed style.
