Qiandao Lake, located in Chun'an County, the western suburb of Hangzhou, Zhejiang Province, China, is 129 kilometers east of Hangzhou and 140 kilometers west of Huangshan. It is the backyard of the Yangtze River Delta and the largest island lake in the world. It is named for its 1078 green islands. I did not enter the main scenic spot of Qiandao Lake, but stayed at the Butterfly Resort on Warm Island of Qiandao Lake. The view of the lake view room is very good. There is a free and open Tianyu Island nearby. The viewing platform overlooks the Qiandao Lake Bridge. It gives you a panoramic view of the lake and a wonderful view of the sunset. Near the hotel, there is a wonderful ride Green Road - Qianfen Green Road. The scenery along the road is very beautiful. Rent a bicycle for a ride, and you're covered with harvest. Because it is not a scenic spot, it avoids the crowds and does not need to buy tickets. It is very relaxing and pleasant to play.
