Set high in the Tibetan plateau, the road to the summit, also known as Heka Shan Yakou, is totally paved. It’s called G214 Highway. Always check the weather forecast before you start your journey: adverse conditions are common. Expect strong winds. The pass has been bypassed by the scenic G0613 (Gongyu Expy Toll Road).

The pass is 110 km (68 miles) long, running from Wenquan Town to Hekazhen. It features steep sections, hitting a 24% of maximum gradient through some of the ramps.
