Balang Mountain is located in the Aba Tibetan and Qiang Autonomous Prefecture, Sichuan Province. It straddles Wenchuan, Xiaojin, and Baoxing counties, serving as a key mountain range between Wolong Nature Reserve and Siguniang Mountain Scenic Area. Key highlights: • Scenery: Famous for its "sea of clouds"—white clouds float halfway up the mountain, dividing it into alpine meadows (upper) and primeval forests (lower). Summer snow (July-August) is also a rare sight. • Ecology: Rich in biodiversity, with alpine flowers blooming (May-August) and new species like Gastrochilus balangshanensis (an orchid) discovered in 2024. • Transport: Accessible via the 8.8km Balang Mountain Tunnel (opened 2016, altitude ~3,850m). The branch road to the mountain pass is permanently closed (since 2023); hiking nearby is an option for views. • Culture: Its ancient trail was part of the Tea-Horse Road, a vital trade/military route since the Three Kingdoms period.
