From Lenzumo, following a comfortable road you reach the former Electricity Power Station where, immediately after the bridge, you take the tractor road which rises, keeping to the left of the valley, as far as Malga Vies. Going up a military path, past the “steps” (a stretch of road carved out of rock), you reach the Cadria summer grazing place. Ascending the north-eastern ridge you are climbing up once again. Then the path (for experienced hikers only) follows the crest until you reach the top of Monte Cadria, the highest mountain in the Alpi di Ledro (junction with 448).
