I think the best star-gazing place around Beijing is Lingshan Natural Scenic Area, which is 22km away from Beijing 122km, and its peak is 2303m above sea level, making it the first peak in Beijing. You can choose a more conventional route for climbing mountains and watching stars, starting from Jiang Shui village at an altitude of 1400m, and taking the sightseeing cableway to reach the star-watching place. Here, the view of stargazing is particularly wide, the dome-like starry sky is over the head, and the stars are close at hand.
