Taman Warisan Negeri Selangor, also known as Selangor State Park, is the largest park in the state. Spanning across Hulu Selangor, Gombak, and Hulu Langat districts, this park is a sanctuary for various wildlife species, dense rainforests, and striking waterfalls such as the popular Chiling and Gabai Falls. As an essential ecological area, the park serves as a significant water catchment zone for the Klang Valley. Nature enthusiasts will appreciate the trekking paths that lead to stunning vistas and lush landscapes. Educational programs about biodiversity and conservation are also held within the park.
