You can start from the village of Alagna, along the Sesia river downhill, before the end of the village you will find a bridge on the left that crosses the river. From here begins the snow-covered path that runs along the cross-country ski track to the hamlet of Gabbio, where you cross the iron bridge to Riva Valdobbia in the locality of Sesietta. Alternatively, you can continue further until you have completed the entire loop of the track.
