The sanctuary has supplied water to Shimla since the late 1800s via a network of gravity-fed pipes.
It acts as a vital carbon sink, boasting some of the densest Himalayan cedar (deodar) stands in the region.
The sanctuary is one of the few remaining areas where the rare Himalayan Yellow-throated Marten can be observed in its natural habitat.
To maintain water purity, absolutely no plastic waste is permitted, and strict littering fines are enforced.
The Shimla Water Catchment Wildlife Sanctuary is a protected forest reserve serving as the primary water source for Shimla city. The sanctuary encompasses 10.25 square kilometers of dense deodar, oak, and pine forests at an altitude ranging from 1,900 to 2,600 meters. Established in the 19th century, it features a colonial-era water pipe system still visible along the walking paths. The area is home to leopards, barking deer, Himalayan yellow-throated martens, and over 100 species of birds, including the Himalayan monal. Visitors must follow a designated 7-kilometer trail that cuts through the core forest zone. The sanctuary is managed by the Himachal Pradesh Forest Department to ensure the preservation of the watershed ecosystem. Access is restricted to foot traffic to minimize human impact on the flora and fauna. There are no permanent human settlements within the sanctuary boundaries.
