Enjoy the beautiful views of the ancient bridges and of the streams of Pontboset. A portion of the circular route follows the initial stretch of stage 23 “Pontboset - Pont-Saint-Martin” of the “Cammino Balteo” trek.

Car access
From Hône take the road to Champorcher and follow it until you have have gone through the village of Pontboset. On the left, take the road that goes down towards the village and park the car near the “Chez Isabel” hotel.

Walking itinerary
From the parking lot, enter the village, take the small road on the right that leads downhill towards the Ayasse stream.
Without crossing the stream, continue left along a beautiful mule track until you cross the stream on a bridge and reach the hamlet of Frontière.
Go past Frontière and on an initially flat stretch, you then go along an uphill stretch to reach the long bridge over the Brenve stream.

After admiring the clear water of the stream among the smooth rocks, go back for about ten metres and take a steep path on the left until you reach a forestry road.
This takes you to the paved road that leads to the village of Crest, and you follow it downhill to the road that goes to Frontière. Turn left and go along for a short distance and then immediately turn right and cross the bridge that spans the Manda stream.

Go down slightly and you reach the paved road; follow it for a while and then turn right and cross the beautiful stone bridge over the Ayasse and then you reach the starting point again.
Go up the paved road as far as the hairpin bend, turn left and cross the bridge that takes you across the Ayasse again. Immediately after the bridge, take the uphill path on the right that leads to the hamlet of Vareisa, where you cross the Ayasse over the bridge and return to the orographic left.
Return to the starting point following the wide path and then the paved road.
