Purple Bamboo Park (also called Zizhuyuan Park or Black Bamboo Park) is one of the seven largest parks in Beijing, China. It is located in the Haidian District of northwestern Beijing.
The park consist of three connecting lakes covering over a total area of 48 hectares. The lakes' eastern shores consist of several small hills, and they were formed with the earth dredged from the lakes, to balance the natural hills on the western shores of the lakes. There are five bridges connecting the lakes, islands and hills into a single integrated area. To the north of the lakes the Changhe River flows through.
Typical of classical Chinese garden style, and like many of Beijing's parks and gardens, it is a mountain-water landscaped garden. Constructed around canals and large lakes, the Bamboo Park is known for its liberal use of verdant bamboo groves. The garden has a variety of bamboos on display, with the variety ranging as much as up to 50 species. There is also an art museum located within the park.
