This challenging hike, covering nearly 20 km, typically takes experienced hikers approximately 8 hours and 12 minutes to complete.
This route is classified as a difficult hike. It demands good physical preparation and is best suited for experienced hikers due to its varied terrain, including rocky sections and significant elevation gain.
The trail offers a diverse landscape, transitioning from lush alpine meadows to challenging rocky sections. You'll traverse the striking Valle di Preda Rossa, known for its red rocks, and encounter the dramatic 'red landscapes of the Corni Bruciati, which resemble Mars'.
Key points of interest include the starting point, Scermendone Bivouac, which is an always-open shelter. You'll also pass through Alpe Vignone, offering expansive valley views, and the quaint Chapel of Prato Maslino. The unique red rock formations of Valle di Preda Rossa and the Martian-like Corni Bruciati are particularly distinctive.
Yes, the route intersects with sections of other official trails, including Sentiero Italia - Tappa D21N, Sentiero Italia - Tappa D20N, and Passo Scermendone-Lago Scermendone.
Given the alpine environment and challenging nature, the best time to hike this route is typically during the warmer months, from late spring to early autumn, when snow has melted and weather conditions are more stable.
While specific regulations for dogs on this exact trail are not provided, generally, dogs are allowed on many trails in the Italian Alps. However, due to the difficult terrain and potential for wildlife encounters, it's advisable to keep dogs on a leash and ensure they are physically capable of handling a strenuous, long hike.
Currently, there are no specific permits or entrance fees required to hike this particular trail within the Val Masino region. However, it's always good practice to check local regulations before your trip, especially if you plan to stay overnight in managed refuges.
Access to Scermendone Bivouac typically involves reaching a starting point in the valley, such as near Preda Rossa, and then hiking up to the bivouac. Parking availability can vary, so it's recommended to research specific parking areas or public transport options to the lower access points before your trip.
Scermendone Bivouac is a welcoming and always-open shelter. It is equipped with four beds, a fireplace, a stove, a gas kitchen, and running water, making it a suitable stop for hikers.
The high ridges throughout the hike provide exceptional photographic opportunities, with sweeping panoramas of the Orobie Alps. You'll also get views of renowned peaks such as Cengalo and Badile from the granite walls of Val di Mello.
