31.9 km

It is not paved. So beware of road cyclists. It works because it is in very good condition and it is rather pleasant because it is very smooth and slight descent.

Château de Montagu

Highlight • Castle

A fortified castle from the end of the medieval period, the ruins of this castle from the beginning of the 15th century offer a fairly precise idea of what it must have been in the days of its splendor.
