The iconic three-story rocket-shaped tower was built in 1969 to offer elevated views of the reservoir.
The reservoir was formerly known as Seletar Reservoir and was officially opened by the Prince of Wales in 1922.
The surrounding forest is home to one of Singapore's largest populations of long-tailed macaques.
The reservoir catchment area is a critical component of Singapore’s four national taps strategy for water sustainability.
The park serves as a common start and end point for long-distance runners utilizing the Mandai road loop.
Upper Seletar Reservoir Park is defined by its iconic rocket-shaped lookout tower, which offers panoramic views of the water and surrounding rainforest. The area functions as part of the Central Catchment Nature Reserve, providing a habitat for long-tailed macaques and various bird species. The reservoir, originally completed in 1920 as the Seletar Reservoir, remains a vital part of Singapore's water supply system. Visitors have access to paved walking paths and open green spaces suitable for fitness activities and picnics. The park provides direct entry points into the surrounding secondary forests for hiking. The landscape features mature trees, including heritage specimens that provide significant shade along the reservoir perimeter.
The top level of the rocket-shaped lookout tower provides the best unobstructed view of the reservoir basin.
Keep food bags and plastic containers securely zipped inside backpacks to avoid attracting macaques.
Bring insect repellent as the dense vegetation and proximity to water contribute to high mosquito activity.
Visit during low-tide conditions if you intend to explore the peripheral muddy banks near the water edge.
Avoid walking alone deep into the forest trails without proper navigation tools, as it is easy to become disoriented in the dense secondary growth.
Do not feed, approach, or provoke the macaques; keep a respectful distance from all wildlife and do not leave trash behind.
