Prince Bay Park is located in the southwest corner of the West Lake, at the foot of Lizhi Peak of Nanping Mountain. It is said that two princes of the Southern Song Dynasty were buried here hence the name. It was originally a lake bay, formed by wind and rain from the mountains, with sand and soil accumulated and turned into a depression swamp.

Prince Bay Park was built in July 1988 and was almost completed in 1989. It originally served as a dumpling site for the dredged materials from the West Lake. During the construction of the park, the surrounding environmental features were taken advantage of. Ponds were dug and slopes were created skillfully to make the terrain undulate, in a pursuit of being “natural and simple".

The total area of Prince Bay Park is about 0.8 square kilometer. The whole park is divided into three sections: east, middle, and west, by park roads and waterways. Prince Bay Park is adjacent to Jiuyao and Nanping Mountain in the south, Jingci Temple, Xiaoyoutian Garden and the sacred roads to Zhang Changshui’s tomb and Zhang Taiyan’s tomb in the east, the beautiful South Peak in the west, and dense dawn redwood forests in the north.

In the park, an open channel of the West Lake Water Diversion Project serves as the main sightseeing line. The Chinese traditional gardening art and modern garden aesthetics co-exist harmoniously, creating fresh and pleasant scenic spots such as Pipizhou, Jade Garden, Xiaoyao Slope, Yulu Pond, Yile Garden, and Taiji Terrace.

The park also has thousands of Japanese Tokyo cherry blossoms and tulips. It is now a famous park for pre-wedding photography and tulip exhibition.
