Kailash MHZL75 - Dream Road

The track entered the Haizi Valley and Changping Valley scenic spots successively. In Haizigou, we pass through Bajiaopeng Sea with an altitude of 4455 meters, Rhinoceros Sea, and Shuanghaizi areas with an altitude of 4370-4560 meters. There are more mixed roads of ice, snow, and gravel, as well as crosscuts and steep drops, which are extremely exposed and require certain mountain driving skills. 97% of the track is a non-mechanically hardened road surface.

The infinite scenery is on the dangerous peaks, and the difficulty of the route will allow you to enjoy more beautiful scenery from more angles. You will have a panoramic view of other peaks such as the south wall of Yaomei Peak and the northern wall of Pomu Peak.

The challenges of this track are high. There are many technical routes with an altitude of over 4,300, and the cut-off time is slightly tighter than other groups. A track that truly combines cross-country running skills and mountaineering skills requires players to have comprehensive abilities.
