Tour description

The mountain range that divides the Blenio valley from the Leventina valley, offers bikers various crossing possibilities, one of which is the "Passo Castrumo". This pass connects two beautiful slopes that are still little known by mountain bike enthusiasts. Unlike the "Bassa di Nara" route, this crossing goes from the Leventina Valley towards the Blenio Valley. The starting and ending point of this route is the town of Acquarossa. Descend towards Biasca along secondary and dirt roads and go up the Leventina Valley on the cycle path to Giornico. After passing the Biaschina bends on the cantonal road, you can reach Calonico by pedaling along the “Strada delle Vigne”(Vineyards Road). From there, continue along the paved forest road to monte Angone (1557 m) (an alp) and reach the Alpe di Laghetto, through suggestive larch woods. A short stretch, only partially cycleable, separates us from the Castrumo Pass (2117 m). Breathtaking views appear in front of your eyes… awe inspiring. The first 15 minutes of descent towards Cancorì must be done with the bike on your shoulder, along a path that is not well marked and is extremely steep (comfortable cycling shoes are recommended). As soon as the steep slope is over, you get on the saddle and, along a short single trail, you reach the dirt road coming from Cambra, which quickly leads you to Cancorì. The resort's restaurant is open from early June to October. The descent towards Acquarossa is done on medium difficulty flowing paths.
