The road is often underwater and severely damaged by rain and landslides and can be closed anytime. The most challenging part of the road runs along the Yalong River. Expect a cliff road without protections and a drop of hundreds of meters (many hundreds of feet) unprotected by guardrails. The road tops out at 4.645m (15,239ft) above the sea level.
