Family stroll on the outskirts of the hamlets of Commeire and Reppaz.
Path in the forest along a bisse with didactic panels. About 30 minutes.
Best period to go there
The old stream that has been put back into water has its source in the torrent of Pont Sec below the village of Commeire. Decorated with didactic panels on the fauna, flora and history of the bisse, it brings the hiker above the village of Reppaz.
Leave the highway at Martigny. Follow the signs for Grand-Saint-Bernard, then leave the main road at Orsières and follow Champex-Lac.
It is also possible to leave the main road at Bovernier and go through Les Valettes but the road is narrow and very winding.
Large free parking lot at the foot of the chairlift
Access by public transport
Take the train to Orsières then the bus to Champex-télé
