Leaving the malga behind, follow the SAT 121A trail towards Passo Valletta until you intersect with the SAT 121 trail. Continue uphill along high mountain pastures until you reach the final steeper section that leads to Passo Valletta (2,694 m). From here, you can admire the northern part of the Brenta Dolomites, including Cima Peller and Sasso Rosso, as well as the Adamello Presanella Group, particularly Croce della Pace and Cima Laste.
From the pass, you can already see the lakes on the Val di Rabbi side. Descending, you first encounter Lago Alto and then Lago Rotondo (2,427 m). The return is along the same route as the ascent.
