Winter trekking starting from Passo San Boldo (BL), where the winter landscape welcomes you with a blanket of pristine snow enveloping the peaks of the Belluno Prealps. The trail winds through enchanted forests, with snow-covered trees creating an almost fairytale atmosphere. Arriving at Casera Costa Curta, you come across a small bivouac nestled in a landscape of snow-covered mountains, with views that open onto peaceful, quiet valleys. Continuing towards the Loff bivouac, the setting becomes even more evocative, with the snow creating an enveloping silence and a welcoming atmosphere. Finally, reaching the Vallon Scuro bivouac means venturing into a wilder and more remote corner, where the mountains and the snow merge into a breathtaking natural scene, offering unique thrills with every step.
