The inhumane climb to Nebelhorn with 45% ramps

Nebelhorn is a high mountain peak at an elevation of 2.068m (6,784ft) above the sea level, located in the Allgäu Alps in Bavaria, Germany, near the village of Oberstdorf. The road to the summit is brutally steep, and the slope -in some parts- is inhuman, with gradients up to 45%. It's one of the highest roads of Germany.

Nebelhorn

It’s said to be one of the steepest and hardest climbs in Europe. The climb has two parts. The first ascent ends on a mountain hut called Edmund Probst Haus, at an elevation of 1.932m above the sea level. The road is pretty narrow and the asphalt is really poor in some sections. Due its steepness, it’s necessary a 4wd car. The pass is not very long, but steep. Expect 20+ percentages in the last kilometers.
Starting from Oberstdorf, the ascent is 7.8 km long. Over this distance, the elevation gain is 1.089 meters. The average percentage is 14 %. After the Edmund Probst Haus mountain hut, the road climbs up 1 km more to a cableway at 2.068m above the sea level. This part is closed to vehicles. It’s a very brutal climb. The scenery is outstanding, the best in the northern Alps. This part was paved in 2008. Starting from Oberstdorf, the ascent is 8.8 km long. Over this distance, the elevation gain is 1.248 meters. The average percentage is 14.2 %.
