Yading is a landscape that Tibetan Buddhism treats as a single sacred object: three snow peaks standing in a triangle, read as a mandala of the three bodhisattvas. Chenrezig, compassion, is the highest at 6,032 metres. Jambeyang, wisdom, is the sharp pyramid to the south, and Chanadorje, power, holds the east; both of them reach 5,958 metres. Pilgrims have circled them for centuries on the kora, the walking circuit that sets out from Chonggu Monastery at 3,880 metres. Glaciers feed the lakes below them — Pearl Lake under Chenrezig's face, and higher up Milk Lake, a turquoise eye rimmed with the pale stone that named it.
Walking here is slow work. The valley floor already lies near 3,900 metres. The standard day climbs from Luorong Pasture at 4,180 metres up a steep trail to Milk Lake at 4,600 and Five-Colour Lake at 4,700, where the air is thin enough that you stop every few steps. Come at dawn. First light finds Jambeyang's pyramid before it reaches the meadow, and holds it pink while the grass is still grey with frost. In the second half of October the larch forests below the peaks turn gold. The outside world came here late, because the range lay in bandit country, and the botanist Joseph Rock's 1931 account for National Geographic was most people's first sight of it. It is no longer remote. An airport 130 kilometres away has cut a two-day road journey to an hour, the reserve can sell twenty thousand tickets a day, and on an October morning you will share the boardwalk.
