The Lower Peirce Reservoir, Singapore’s second-oldest reservoir, was built by impounding the upper reaches of the Kallang River and was commissioned in 1912. Lower Peirce Trail runs through the forest and along the edge of this reservoir.
You can enter the boardwalk via several trailheads. The Havea and Costus trail entrances start at Casuarina Road, or you can also make your way in through Lower Seletar Reservoir Park. Once on the boardwalk, you will come across Cyathea, Bamboo, and Oncospermum trails.
Along this charming 900-metre boardwalk, you’ll be greeted with captivating views of the forest that line the lake as well as a variety of flora and fauna. The forest here is considered a mature secondary rainforest and is still dotted with numerous rubber trees and oil palms – visible reminders of a past when vast areas of Singapore were covered with plantations.
