Passo di Publino, Mountain pass in Lombardy, Italy.

Passo di Publino is a mountain pass at 2,368 metres between the upper Val Brembana (province of Bergamo) and the Val del Livrio, a tributary valley of the Valtellina. It is the lowest point of the ridge linking Corno Stella to Pizzo Zerna. The path does not cross the watershed at its lowest point, where the Valtellina side is too steep, but higher to the east toward Pizzo Zerna.

The pass lies at 2,368 m on the lowest point of the ridge between Corno Stella and Pizzo Zerna, on the divide between the upper Val Brembana (Bergamo) and the Val del Livrio, which drains into the Valtellina. The shortest approach starts at Carona, passes the hamlet of Pagliari and a waterfall, then leaves the car track near a fountain for the Val Sambuzza trail. The marked path crosses the watershed east of the lowest saddle, toward Pizzo Zerna, and drops in under an hour to Lake Publino and the Caprari refuge.

The pass marks the watershed between the Brembana side and the Livrio valley, which feeds the Valtellina. Walkers coming up from Carona pass the hamlet of Pagliari and a waterfall before the trail forks near a small fountain, where a sign points to Val Sambuzza and the pass. Just below the saddle stands the Pedrinelli bivouac, a small shelter used by shepherds and ski mountaineers.

The climb requires mountain experience and sturdy boots, particularly when wet or during early season when snow may linger. Plan your route early in the day and check conditions before starting, as weather at the pass can shift quickly.

A side route heading east to Pizzo Zerna lets visitors climb that summit and descend toward Lake Publino and the Caprari shelter area nearby. This detour offers fewer crowds and a chance to see how the valleys look from the opposite direction.
