From Morbegno by vehicle, go up Val Gerola to Gerola from where take the road to Castello/Laveggiolo. Once in Laveggiolo (1460m) the paved road ends near a large parking lot where the itinerary begins (no permit or parking ticket required). From Laveggiolo, take the dirt road that initially goes up the Val Vedrano, leading to the small wooden bridge that crosses the stream. At 1650 m. the slightly downhill road turns left to climb with a few switchbacks up the mountainside to an altitude of 1850 m. from where on the flat after about 1 km you reach the hut. From the start, always follow the road, ignoring the official signs for the ref. Trona, which otherwise follows the direct path, not feasible with the help of Jolette. The Trona Soliva refuge, located in the Orobie Valtellinasi Park in the Valle della Pietra at an elevation of 1907 m, is in the presence of Pizzo dei Tre Signori, Pizzo Trona and the Trona and Inferno dams. The refuge is located in a scenic area where nearby you can visit the "Calecc" still in use by shepherds for the production of typical local cheese.
