I think that whoever named this road had never travelled in the Himalayas or the Karakorum. The road is really pretty dangerous, especially if you have to take the old road if the new one is blocked by landslides. It has become very popular to descend this extreme road by mountain bike. It's a one hour drive through the mountain pass from Paz to Coroico. The passage of the summit is at 4700 meters above sea level, surrounded by huge mountains that are over 5000 meters, and is the main passage between Paz and Yungas (Amazon basin). The route descends 3600 meters in altitude in 64 kilometres, from 4700 meters to the subtropical valleys of the Yungas, passing the villages of Yolosa (1200 meters) and Coroico (1500 meters).
