The zigzag path allows you to gain altitude well, even when cycling. It is relatively steep, but since it is a well-maintained alpine path, it remains within the realm of the possible! The higher you go, the better the views into the valley become!

If you're on the Nufenenpass with your MTB, a flowing forest section awaits you in the lower part. Soft natural ground and a few turns allow you to cruise quickly through the fir trees here. Since it's also a hiking trail, you need to consider potential encounters with pedestrians when choosing your speed. Additionally, you might even encounter bikes coming uphill!

On the Obergoms side of the Nufenen Pass, the road winds its way up and down the slope over ten hairpin bends. From the second-to-last bend before the pass, a gravel road leads across to the Griessee reservoir. From here you can enjoy a last view of the valley before dropping into the S2 trail. This zigzags down a mountain ridge quite steeply, requiring maximum concentration, good skills, and a focus on the front wheel!

The ascents and descents are not easy at all: most sections are at least 15% steep, with a few 25% sections!

Magnificent view of the Valais Alpine panorama. With the Biobike, this view has to be hard-earned, with the E-bike the whole thing becomes a pleasure.
