Langmusi & Zhagana

Langmusi, a town where the Bailong River divides two monasteries between Gansu and Sichuan, forms the southern Gannan route with Zhagana, the "stone box", Gahai Lake and the Zecha Stone Forest.

Langmusi and Zhagana lie in the south of Gannan Tibetan Autonomous Prefecture, the heart of the "southern Gannan route" where Gannan meets northwest Sichuan. In Langmusi Town (about 3,300 m), a stream at the source of the Bailong River splits the town into a Gansu half and a Sichuan half: on the north bank is Sertri Monastery in Luqu, Gansu, and on the south bank is Kirti Monastery in Zoigê, Sichuan. Outside town are the Namo Grand Canyon, the sky burial platform and the Red Rock Cliff. About 100 km east in Diebu County, Zhagana is a "stone box" ringed by limestone peaks of the Min Mountains, famed for its four Tibetan villages, the Fairy Meadow and the Rock's Road hike. About 50 km north, Luqu County has Gahai Lake and the Zecha Stone Forest. Climate: highland continental, with cool summers (daytime 15–22°C) and long, harsh winters (often below –15°C). The best season is July–September for grasslands and hiking; late September to mid-October brings the finest autumn color in Zhagana and Diebu; from November to April some guesthouses close and mountain roads are snowed over. Getting there: the nearest airports are Gannan Xiahe Airport, and Hongyuan and Jiuzhai Huanglong airports on the Zoigê (Tangke) side. The bus from Lanzhou via Hezuo to Langmusi takes about 7–8 hours, Hezuo to Langmusi about 3 hours, and Langmusi to Diebu to Zhagana about 2.5 hours; public transport between sights is sparse, so self-driving or a hired car is recommended. Suggested time: 1–2 days each in Langmusi and Zhagana, or 3–4 days including Gahai and Zecha; the trip can be strung into a loop with Zoigê's Flower Lake and Labrang Monastery in Xiahe. Notes: the whole area lies at 3,000–3,500 m, so watch for altitude sickness and protect yourself from sun and cold; photography is not allowed inside monastery halls, and the prayer circuit goes clockwise; do not crowd around or photograph sky burials; in Zhagana's peak season (July–October) book guesthouses in advance; for the Rock's Road hike, hire a local guide.
