Daocheng county sits on the south-western edge of Sichuan, in the Garzê Tibetan Autonomous Prefecture on the south-eastern rim of the Qinghai-Tibet Plateau, and it is the landscape the phrase the last Shangri-La was coined for. North high, south low, range after range running away to the horizon, with snow peaks, glaciers, gorges, forest, meadow and lakes in between. Three of those peaks stand in a rough triangle inside the Yading reserve, and Tibetan tradition says the Fifth Dalai Lama named them himself: Xiannairi, the north peak, is Avalokitesvara; Yangmaiyong, the south, is Manjushri; Xianuoduoji, the east, is Vajrapani.
The reserve is built like a staircase up a valley, which is why two days is the standard way to walk it. The short line is the easy one: an electric cart from Longtongba, then a gentle walk from the Chonggu Temple lawn up to Pearl Lake, a green pool at 4,100 m directly below Xiannairi. The long line is the one everybody talks about — a second cart out to the Luorong pasture at 4,200 m, then hours of climbing to Milk Lake at 4,500 m and on to Five-Colour Lake at 4,600 m, where the water throws five colours in the light.
The altitude is the other half of the trip, and it is not a footnote. The reserve floor sits around 4,000 m. Daocheng town, where you spend your first night, is 3,740 m. The sensible sequence is to arrive, do nothing much for a day, and only then drive the three hours in to Yading village — the people who try to walk the long trail on the day they arrive are the ones who end up in the back of a car with an oxygen canister.
None of this is comfortable and the place does not pretend otherwise. The beds in Yading village are basic and mostly without showers, the food inside the reserve barely exists, and the weather turns by the hour. What you get is one of the last genuinely wild high places in China, and three peaks standing over it that people have been walking around for a thousand years.
