Siguniang Mountain Dafeng Peak Climb

The climb to Dafeng Peak, the lowest and most frequently summited of the four Siguniang massif peaks at just over 5,000 metres, sets out from a base camp in Changping Valley near Rilong Town in Aba Prefecture, Sichuan, about 225 km west of central Chengdu. This is a technical alpine ascent rather than a hike: the upper section crosses glaciated terrain requiring crampons, an ice axe and rope work, and prior scrambling or alpine mountaineering experience is strongly recommended before attempting it. There is no formal age limit, but the scenic area management office requires climbers to register with a mountaineering permit and typically expects participants to climb with a registered guide service rather than solo. The permit and management fee cover access to the route and rescue coordination; climbers bring or rent technical mountaineering boots, a cold-weather sleeping bag rated below -15C, and layered clothing, while rope, harness and climbing hardware are usually arranged through the guide service as part of the multi-day package. Guide services affiliated with the Siguniang Mountain Scenic Area management office are the recognized operators for the route, and they run a safety briefing covering glacier crossing technique, weather monitoring and turnaround times before the summit push; in the event of injury or altitude illness, evacuation relies on guide-assisted descent to base camp, since no vehicle or helicopter access exists above the trailhead. The recommended climbing window is May and September-October, when the summer monsoon has passed or not yet arrived and before winter ice makes the upper glacier unstable; climbers should avoid attempting the route during the July-August monsoon, when whiteout conditions and rockfall risk increase sharply.
