Saishiteng Mountain Astronomical Observatory
赛什腾山天文观测基地
One of the best optical observatory sites in the Eastern Hemisphere, with more than 300 clear nights a year. The mountaintop is dotted with the domes of research institutions' telescopes.
Saishiteng Mountain lies about 50 kilometers southeast of Lenghu town, with a summit at roughly 4,200 meters above sea level. Site surveys identified it as one of the finest optical observation sites in the Eastern Hemisphere, with more than 300 observable nights per year. The Lenghu Astronomical Observatory Base has been built here and houses dozens of telescopes, including several large optical instruments. The summit observation area is a research facility, so whether visitors may go up, opening hours, and booking procedures follow local announcements. Lenghu town has an astronomy science museum and stargazing spots, and you can also photograph the night sky in the Gobi outside town. Watch for altitude sickness and keep warm when going up.
