View of the Forest and the Eiffel Tower

Highlight • Viewpoint

Here we have a superb view of the region's forest massif, with the Eiffel Tower appearing timidly in the background. Another way to contemplate the icon of the French capital in the middle of nature!

Crossing the Buzot river

Highlight • Bridge

This footbridge allows you to cross the ru de Buzot. Be careful though! It is quite cramped and you can fall into the water. It is best to cross on foot and carry your bike.
