Three Parallel Rivers of Yunnan云南三江并流保护区 · Sān Jiāng Bìngliú — three of Asia's great rivers, running side by side and never touching
In the mountainous northwest corner of Yunnan, the upper Yangtze, Mekong and Salween run roughly parallel for hundreds of kilometers through gorges up to 3,000 meters deep, walled in by glaciated peaks over 6,000 meters high. It's a single UNESCO listing spread across eight scattered protected-area clusters, not one park you can walk into.
Three of Asia's rivers, a stone's throw apart, refusing to merge.
The Three Parallel Rivers of Yunnan Protected Areas gathers 15 protected areas into eight clusters across 1.7 million hectares of northwest Yunnan. Through it run the upper reaches of three of Asia's great rivers — the Yangtze (as the Jinsha), the Mekong (as the Lancang) and the Salween (as the Nu) — flowing north to south in near-parallel gorges for hundreds of kilometers, in places 3,000 meters deep, twice the depth of the Grand Canyon.
It's an epicenter of Chinese biodiversity and one of the richest temperate regions on Earth for plant and animal life, largely because the terrain compresses so many climate zones into so little horizontal distance — subtropical valley floor to alpine glacier within a day's drive. At their closest, the Mekong and Salween run just 18.6 km apart without ever joining.
This is a serial, sprawling site, not a single park with one gate. Almost everyone visits one or two accessible corners of it — Tiger Leaping Gorge and Meili Snow Mountain are the two nearly everyone reaches — rather than the whole 1.7 million hectares.
One listing, eight scattered clusters.
This is a serial site: eight geographically separate clusters of protected land bundled into one UNESCO inscription because together they capture the same phenomenon — three great rivers boxed side by side by parallel mountain ranges. You visit whichever corner is on your route, not the whole thing.
Tiger Leaping Gorge 虎跳峡
The most-visited corner: a spectacular gorge on the upper Yangtze (Jinsha) between Lijiang and Shangri-La, walkable via a well-known two-day trekking trail.
Meili Snow Mountain / Baima Xueshan 梅里雪山 / 白马雪山
A glaciated range near Deqin, its 6,740 m Kawagebo peak considered sacred and never climbed; the Mingyong Glacier descends unusually low for its latitude.
Nujiang (Salween) Grand Canyon 怒江大峡谷
The wildest and least-visited of the three rivers, running through remote Nujiang Prefecture along a rough provincial road.
Laojun Mountain & Haba Snow Mountain 老君山 / 哈巴雪山
Additional glaciated clusters near Lijiang, popular with hikers and climbers as a quieter alternative to the main gorge routes.
The corners travelers actually reach.
The full site is far too vast to tour; these are the accessible pieces most visitors build a trip around.

Tiger Leaping Gorge 虎跳峡
One of the deepest gorges on Earth, on the upper Yangtze — a famous two-day trekking trail along the high trail, or a short walk to the roaring narrows at river level.From Lijiang ~2 h by bus · From Shangri-La ~2-3 h
Meili Snow Mountain 梅里雪山
A sacred, unclimbed 6,740 m peak near Deqin, best viewed at dawn from the Feilai Temple viewing platform when the summit catches the first light.From Shangri-La several hours to Deqin · Best at sunrise
Mingyong Glacier 明永冰川
A glacier tongue descending from Kawagebo to just 2,700 m — unusually low for its latitude — reached by a hike or pony trail from Mingyong village.Near Deqin
Nujiang Grand Canyon 怒江大峡谷
The Salween's remote, rugged gorge through Nujiang Prefecture — the least developed and least visited of the three rivers, for travelers with extra time.Access provincial road S228
Spring and autumn, before the summer rains.
April–May and September–October bring the clearest mountain views and most stable trekking conditions. Summer brings monsoon rain and landslide risk on gorge roads; winter is cold at altitude but often gives the clearest skies for viewing snow peaks like Meili, if you can handle the cold.
Meili's summit is notoriously shy. Cloud hides Kawagebo more often than not, even in good seasons — build in a spare day at Feilai Temple if seeing the peak matters to you, and don't count on a single sunrise attempt.
For foreign travelers.
- Treat this as several separate side trips woven into a Yunnan itinerary, not one destination — Tiger Leaping Gorge from Lijiang, Meili Snow Mountain from Shangri-La, rather than trying to see it all.
- Fly into Lijiang or Shangri-La; both connect easily to Kunming and have grown into trekking and photography hubs in their own right.
- Altitude matters — Shangri-La and Deqin sit above 3,000 m; allow a day to acclimatize before strenuous hikes.
- Roads into Nujiang and toward Deqin can close after heavy rain or snow; check conditions locally before setting out.
- Pair with Tibetan culture in the region — Shangri-La's Tibetan Buddhist heritage (Songzanlin Monastery) is a natural extension.
