From the former Capuchin novitiate that replaced the silk factory, climb to the summit of Mont Brian. It offers sweeping views over the Rhône and Drôme valleys to the Vercors and Diois.
From the parking lot, head south through the IME towards Parpaillote, Mondchaud and Pied de Courcoussat on a good path that becomes a footpath towards Brian Nord, which you reach in 35 minutes.
From here, you can make a round trip to the summit of Mont Brian. From Brian Nord, take the path through the undergrowth and downhill towards Fonds de Brian, leaving the good path for a path on the right, down to the houses, which you leave on the left, for a path up to L'Adret.
Keep to the left and climb a little further to find an old cereal threshing floor with a fluted roller. Find a good path again, then go right along the field to take a downhill path in the opposite corner, taking you back to the IME parking lot.
