At 2,478 meters above sea level, the Nufenen Pass (Nufenenpass in German) connects the Goms Valley in the upper Valais with the Bedretto Valley in the upper Ticino. From Airolo, the climb is approximately 22 kilometers (average gradient 5.6%), while from Ulrichen it is shorter but more challenging: 14 kilometers at an average gradient of approximately 7.9%.

You've conquered the Nufenen Pass (Passo della Novena) by the road sign at an altitude of 2,477 meters. The pass also marks the cantonal border between Valais and Ticino. The pass is one of the youngest mountain passes in Switzerland, having only been built in 1964 and opened five years later. As the highest pass located entirely within Switzerland, it offers a special attraction for road cyclists. However, the approach from both sides is challenging, steep and often windy. Both routes involve over 1,000 meters of elevation gain. Since it's located far from any major towns, chances are your legs will already be a bit tired by the time the climbs begin.

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

Plenty of space to park. From here you can also start tours towards Airolo or Ulrichen and then take the post bus back.

If you are waiting for the post bus (Airolo-Ulrichen-Oberwald route): It comes every two hours at most.

Magnificent view of the Valais Alps. With the Biobike you have to work hard to get this view, but with the E-bike the whole thing becomes a pleasure.
