Beautiful park in the Haidian District of Beijing renowned for its Cherry blossom and Roseacea trees. Best time to go is early spring when the trees bloom with cherry blossoms. There's a lot of land to cover so it's perfect for a nice relaxed walk or a gentle jog early in the morning. I absolutely loved the early morning tai chi practitioners and others dancing to traditional Chinese music. Go early as it does get crowded later on in the morning.
