Winter trekking departing from Passo San Boldo (BL), where the winter landscape welcomes you with a blanket of white snow that envelops the peaks of the Belluno Prealps. The trail winds through enchanted forests, with snow-covered trees that create an almost fairy-tale atmosphere. You'll arrive at Casera Costa Curta, a small bivouac nestled in a landscape of snow-capped mountains, with views that open onto peaceful and quiet valleys. Continuing towards the Loff bivouac, the environment becomes even more evocative, with the snow creating an enveloping silence and a cozy atmosphere. Finally, reaching the Vallon Scuro bivouac means entering a wilder and more remote corner, where the mountains and the snow merge into a breathtaking natural setting, offering unique emotions with every step.
