The Sentiero runs mainly on the Calanca side of the mountain range which is nearly 3000m above sea level; only the start in San Bernardino and the descent to Santa Maria are on the Misox valley side. The trail winds up towards the heavens and leads hiker high above the valley along crevices and from hut to hut. Besides the manned and serviced «Capanna Buffalora» hut, there are three self-service Rifugi (refuge huts), well-spaced out on the Sentiero and possessing a very special charm indeed.
San Bernardino village can be used as a starting point as well, with public transport links there better than at pass altitude.
A steady foot and head for heights are required.
