The descent from Cari is not possible. The asphalt is torn up for kilometers and is only roughly gravelled.

The asphalt on the descent is torn up for kilometers and only roughly gravelled. Actually not passable with a road bike. Better to turn around directly in Cari and ride back the same route.

it's a mountain road, what do you expect, a highway? sure with a SUV it's a bit narrow but, it's asphalted and at altitude with dirt it's like on the white roads in Tuscany, moreover the Alpe Piora is famous for its cheese and the Lake Cadagno is world-famous for its three layers

As others have already said: It's tough, steep, and beautiful here! It's best to split the climb into shorter stages, so the 2,000 meters of elevation gain over 30 kilometers from Bignasco aren't quite as terrifyingly daunting. From Bignasco to Prato Sornico, it's rarely very steep. There are a few flat sections where you can pick up a decent pace. After Mogno (visit the church in Botta) and up to Fusio, things really get going for the first time. Many hairpin bends soften the incredibly nasty ramps, but your legs will still be tested here! Up to the Sambucco reservoir, it becomes truly idyllic, green, and quiet. There are a few tough climbs, but even here, the difficulty is still manageable. There's a fountain at the summer restaurant: fill up your bidons again, because there are only streams and gullies here. After the relaxing flat section by the lake, the final and most strenuous part of the climb follows. The scenery is stunning, but it's steep all the way to the top! Wow!

While cars and trucks hum along the highway below in the valley, you'll have peace and quiet on your drive up to Carì. The road to the holiday home complex on the sun-drenched southern slope of the Valle Leventine is generally quiet, making it ideal for gaining altitude. Twenty hairpin bends with single-digit gradients will take you up a good twelve kilometers.
