From the old lime kiln, go up to the left on the track towards the ferny area. Continue on the track. You’ll reach the quarries. Go up on the slightly steep path to the right. Turn left and go up to the cross and the Castet Bielh. Go down to the right towards a cross by the path that crosses a ditch to see the observation post (1939-1944). Go down crossing a wall in ruins to reach the Ermitage hill.
