Erlong Mountain is not very high. Suitable for all ages. It only takes more than two hours for an old man in his sixties and seventies to stop and go. If young people walk fast, about an hour is enough. Qingdao Laoshan Erlongshan Eco-tourism Zone is located in the north of Laoshan Yangkou Scenic Area, bordering Yangkou Scenic Area and Laoshan National Forest Park in the south and Wanggezhuang Office and Qingdao Seaside Sightseeing Avenue in the north. The scenic spot has a pleasant climate, beautiful scenery, complete infrastructure and superior geographical location. There are two reservoirs, Wangxiao Reservoir and Tangziguan Reservoir, which are the birthplaces of high-quality Laoshan water. Binyang Highway crosses, and the traffic and communication conditions are very convenient. Erlongshan is the hinterland of Laoshan National Forest Park. There are towering old trees and strange rocks in the planning scenic area, which is foggy all the year round, and the mountain greening rate is over 90%.
