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!

Artificial lake at 2310 meters above sea level which marks the end of the Val Maggia. The climb to reach it is challenging.
