Butte Ronde route

Short hike in the Bois de la Butte Ronde and Vallée des Grès. Along some of the paths, you can admire the enormous hundred-year-old oak trees. The Rambouillet Forest is managed by the ONF. The paths are well marked and the natural environment is very varied. You can easily go from birch and hornbeam trees to magnificent oaks, and from heather to ferns or grasses.

This is the second time I've done this hike and I find it a bit monotonous with its long straight stretch in the first part. It is currently passable despite the recent rains. No elevation gain, an easy walk to follow.
