Western Sichuan climbs in stages: river valley, forested gorge, then open plateau. Past Songpan the land loosens into the Ruoergai Grassland, a high country of wet meadows and grazing herds at roughly 3,300 to 3,600 metres. It is sometimes called the Songpan Plateau. Not a single lawn but a mix of pasture, marsh and protected wetland, it holds black-necked cranes, sika deer, white swans and red pandas. Tangke horses, a local breed long praised in Chinese poetry, graze here too.
Moon Bay and the Hongyuan Grassland
Moon Bay sits in Hongyuan County, in the Aba Tibetan and Qiang Autonomous Prefecture. The river bends in a long crescent across open pasture, and that curve is the whole attraction. Light does most of the work: morning sun on the water, herds moving through the grass, birds along the banks, colour spreading at dusk. Stop and look. There is nothing here to rush toward.
Hetai Hot Spring Valley
Hetai is a developed hot-spring area on the plateau route. After cold wind and a long drive, warm water and a wide horizon are welcome. Treat it as a pause in the journey rather than a destination, and confirm facilities and access before you set out, since they change with the season.
A Three-Day Loop from Chengdu
Day 1: Chengdu to Hongyuan via Lixian and Moon Bay
Leaving Chengdu, the road passes Yingxiu, Wenchuan and Lixian, climbing through river valleys and mountain slopes. It is a long drive, so treat the day as a transfer with a scenic pause rather than a full day of sightseeing. Moon Bay gives the first real sense of the plateau: walk to a viewpoint, watch the river curve through the grass, then sleep in Hongyuan.
Day 2: Hongyuan to Chuanzhusi via Ruoergai Grassland, Hetai and Flower Lake
The second day crosses the grassland proper. Stops may include Hetai, the Ruoergai Flower Lake scenic area, and open pasture where local operators run horse riding, archery and kite flying. What is on depends on the weather and who is organising, so ask rather than assume a fixed programme.
Flower Lake belongs to the wetland system that shapes this part of the plateau. Water, reeds and grass pull in birds and shift the reflections through the day. Stay on the established paths at viewpoints and give wildlife room. Near Chuanzhusi, some itineraries include an evening of Tibetan food and Guozhuang dancing: staged, enjoyable for what it is, and no substitute for ordinary village life.
Day 3: Chuanzhusi to Chengdu via Songpinggou
The return can take in the Red Army Long March memorial near Chuanzhusi, a stop at Diexi Haizi and a visit to Songpinggou, a valley of lakes and waterfalls. Named stops there include Baishi Lake, Mo Lake, Wucai Pool, Long Lake, Baila Waterfall and Upper Baila Lake. Walking paths and shuttle services link the main viewpoints.
Practical Notes for the Plateau
Ruoergai's weather can turn from rain to sun inside an hour. When the light opens, pull over somewhere safe instead of holding out for a better viewpoint. Many roads cross open pasture: do not drive off established tracks without permission, and ask before using hill roads or pasture access points that local families manage. A small charge is normal.
In peak season, book Hongyuan or Chuanzhusi accommodation ahead and choose a property with recent reviews. Bring sun protection, a windproof outer layer, warm clothes, a hat, sunglasses, rain gear, lip balm and sturdy shoes; heels are useless on grassland and valley paths.
Altitude is the thing to respect. The grassland is high enough to affect some visitors, so allow a day to adjust, drink water and take the first day slowly. Watch for livestock on the road. Access, transport and activity details change from year to year, so check official local sources before travelling.
