Tour touching the beautiful lower Frisson Lake and Alberghi Lake. The view over the summit of Mt. Frisson is particularly beautiful: for its pyramidal shape, it seems a "little Cervino". Along the way, the geological features are particularly interesting: the first part of the itinerary develops on calcareous soils where water has shaped the rocks and penetrates deeply. In its upper section, the trail develops on soils of crystalline origin, not very permeable and, as a consequence, rich in surface waters.
From the small square, follow the dirt road until you reach a bend where, on the left, the mule track leading to the lakes branches off. After crossing a small creek, you will find a junction: go ahead along the right branch that, after a flat stretch, enters the gorge and climbs with steep hairpin bends. Afterwards, the main trail follows the bottom of the gully and then alternates short flat stretches with steep stretches, reaching a junction: abandon the left branch leading to Alberghi Lake (and that will be used for the return journey) and take on the right a narrow trail climbing with short hairpin bends up to the plateau where you will find a Gias (1,823m).
Beyond this, the trail starts climbing with hairpin bends next to a rocky spur. Along a rather steep uphill trail, head for the summit of a rounded spur where a mountain hut stands out. Before reaching the hut, the trail divides in two: continue on the left and reach Frisson lower lake (2,057m).
From the lake, a marked track cuts towards the east steep grassy and rocky slopes at the foot of the northern slope of Mt. Frisson, and finds a passage with various ups and downs and, after the last stony ground, goes downhill to the western shore of Alberghi Lake, from which you can follow the evident downhill trail meeting the outward itinerary.
