Address: Sanjiangyuan area, southern Qinghai, China

Sanjiangyuan (literally ‘Source of Three Rivers’) is an immense protected area on the Tibetan Plateau that contains the headwaters of the Yellow, the Yangtze and the Mekong. The area includes extensive alpine wetlands, swamp meadows, grasslands and mountain ranges across a region larger than many countries.

Conservation efforts began with the Sanjiangyuan National Nature Reserve established in 2000; in the national park pilot program the Sanjiangyuan National Park was created as the first of the new parks in late 2021. Management combines strictly protected core zones, buffer zones and multiple-use experimental zones aimed at protecting water, grassland and wildlife while phasing out some damaging activities.

The park is remote and sparsely populated: traditional pastoralism still shapes the landscape although resettlement and grazing restrictions have been applied in core areas. Visitors find a fragile, high-altitude environment with limited services, great seasonal contrasts and opportunities to see specialised birds and mammals adapted to the plateau.

  • Headwaters of the Yellow, Yangtze and Mekong: Wide alpine marshes and springs where streams that become three of Asia’s great rivers begin are the park’s defining landscapes and photographic highlights.
  • A'nimaqin and other conservation subareas: Functional subareas such as A’nimaqin, Suojia-Qumahe and Tongtian He have ranger stations and marked conservation projects illustrating ecosystem protection on the plateau.
  • Alpine wetlands and swamp meadows: Expansive high-altitude wetland complexes support migratory waterfowl and are central to the park’s water-storage and biodiversity values.
  • High-altitude wildlife: Look for plateau specialists from brown-headed gulls and Tibetan snowfinches to larger mammals such as wild yak, chiru and, in remote areas, species like snow leopard and Tibetan blue bear.
  • Tibetan pastoral landscapes and culture: Pastoral scenes, seasonal camps and small settlements give a sense of traditional nomadic life and the social changes driven by conservation and resettlement policies.

Getting There & Around

How to Get to Sanjiangyuan#

The nearest major city and administrative centre is Xining; the park covers vast, remote parts of southern Qinghai and has no single entry town. Xining has the region’s main airport and railway connections and is where park management and many longer trips are organized.

From Xining the last stretches are by long road journeys into remote plateau country; access is by regional roads and 4x4 tracks and some conservation subareas have ranger stations reachable only by local vehicles or guided trips, so arrange transport and local guidance in Xining or the closest county towns.

Tips for Visiting Sanjiangyuan#

  • Acclimatize in Xining or lower-altitude towns before venturing into Sanjiangyuan to reduce the risk of altitude sickness.
  • Services, accommodation and mobile coverage are sparse; plan fuel, food and overnight stops carefully and expect basic conditions in remote areas.
  • Respect protection zones: core areas are strictly managed and parts of the park may be off-limits or require permission from authorities.
  • Weather is highly variable and cold even in summer; bring warm layers, sun protection and waterproof gear.
  • Hire a local guide or join a licensed tour for navigation, cultural context and to follow conservation rules.
