Description of the route
Go down to the lower part of the village centre and take the beautiful shaded path on your left that leads to the Ayasse at the locality called Frontière; reach the hamlet by crossing the stream on a wooden bridge and, after going through the village, follow the wide path first downhill then flat along the Ayasse. With a last short stretch slightly uphill, reach the long bridge that cuts the Brenve stream just downstream from the ravine. This ravine can be observed from two points: in the lower part, starting from the built-up area of Frontière and continuing up to a wooden bridge along the path towards Hône; in the upper part, leaving the car on the road to Crest, near the third bend and following the indications of the panel located at the beginning of the path reaching it. All directions can be found from the village centre (Capoluogo).
