Alien sites, Lake Kruk and Lake Tossu are three scenic spots, not far from each other. The joint ticket is 20 yuan, which is a symbolic receipt. If we take the Qinghai Great Ring Road, we usually go to Dachaidan Town after seeing Dakar Salt Lake, take it down to Kruk Lake at high speed, and then go to the man-made alien sites on the roadside. It's not interesting. For a pure tour, we must go to Tosu Lake. It's 15 kilometers to drive inside that is the Tosu Lake and the real alien sites. On the way in, we can only see them along the Kruk Lake. The beautiful scenery of Lake Crook. Real alien sites are also found on Baigong Mountain, along the lakeside, at least these two sites are much more reliable than those on the highway.
