Four-sister Mountains (四姑娘山, Siguniang Mountains) is a National AAAA scenic spot and a dreamland for nature lovers, noted for its snow peaks, blue sky, white clouds, forests, rushing waterfalls and alpine meadows.

The main attraction of this scenic spot is the unspoiled natural beauty, especially the superb sight of the splendid, awe-inspiring snow-topped peaks rising high above the horizon against the backdrop of blue sky.

The scenic spot is about 220 kilometers from Chengdu, accessible to bus service.

Yaomeifeng (namely the youngest sister), the tallest peak among the "four sisters" and the second tallest mountain in Sichuan, is known as the "Queen of Sichuan's Mountains", standing 6, 250 meters above the sea level. The other "three sisters" are lesser in height (but all have altitudes well above 5, 000 meters) and hence are more popular aims for mountain climbers, while Yaomeifeng remains almost an insurmountable peak and very few attempts to its top were successful.
