This route was planned by komoot.
The full hike from Colle Valcavera to Colle Serour is estimated to take approximately 5 hours and 30 minutes. While the direct path between the two passes (the P46 trail itself) can be covered in about 2 to 2.5 hours, the Komoot tour includes additional segments or a more leisurely pace, leading to the longer overall duration.
Komoot rates this hike as difficult. While much of the P46 trail traverses comfortable mezzo-costa (half-slope) terrain with grassy sections, there are also detrital flows, rocky parts, and some Slightly Exposed Trail Sections. Good physical preparation is essential, and it's not recommended when snow is present.
The ideal time to hike this trail is in late spring after the snow has melted, typically from late May through early July. This is when the trail truly lives up to its name, "Lou viol d'es fiour" (the "Path of Flowers"), with vibrant displays of lilies, anemones, tulips, and orchids. Summer and early autumn also offer excellent conditions, but always check local weather and trail conditions before heading out.
Generally, dogs are allowed on trails in this region. However, given the high-altitude environment, potentially rocky and exposed sections, and the presence of wildlife, it's crucial to keep your dog on a leash. Ensure your dog is well-conditioned for a long, difficult hike and carry enough water for both of you.
The trail officially starts at Valcavera Pass (Colle Valcavera). There is typically parking available directly at the pass, which serves as a common starting point for several routes in the area. Access is usually via mountain roads, so ensure your vehicle is suitable for such terrain.
No, there are generally no specific permits or entrance fees required to hike the P46 trail from Colle Valcavera to Colle Serour. However, always respect local regulations and private property signage if encountered.
The terrain is varied, primarily consisting of grassy slopes at a comfortable mezzo-costa (half-slope) elevation. You will also encounter some detrital flows and rocky sections. The path is well-defined, but the high-altitude environment means you should be prepared for uneven surfaces and potential exposure.
The primary highlight is the stunning floral display in late spring, earning it the name "Path of Flowers." You'll also experience panoramic views throughout, particularly around Passo d'Eguiette, offering vistas of the surrounding alpine environment and the upper Arma Valley. The entire route provides an immersive experience in wild, captivating landscapes.
Yes, the route intersects with sections of other trails. Notably, about 32% of this Komoot tour overlaps with the Sentiero Italia - Tappa E15, and 26% with the SICAI Ciclo. You might also encounter parts of the Via normale al Mone Salè and the Strada ex Militare verso Gardetta.
While the Komoot tour is rated difficult, the P46 trail itself between Colle Valcavera and Colle Serour is often described as comfortable for hiking. The 'difficult' rating likely comes from the overall length, elevation changes, and potentially exposed sections. If you're looking for a less strenuous experience, focus on the core P46 segment, but always be prepared for high-altitude conditions and potential exposure, especially at the Slightly Exposed Trail Section.
