It is a branch of the Val Brembana, known for the Orrido della Val Taleggio (a deep gorge of about 3km) and the legendary stracchino. An excellent base for excursions is the Gherardi Refuge.
The pass is easily accessible from the Mezzeno huts (Roncobello) and allows you to descend quickly to the Twin Lakes or to reach various secondary peaks without too much difference in height
The Sentiero dei Fiori is part of the circumnavigation of the Arera and also touches Mount Corna Piana: you pass by the Capanna 2000 refuge. Here there are unique floral species.
