This group of boardwalks through the Central Catchment Nature Reserve brings you through one of Singapore’s last remaining mature secondary forests and over the edge of Lower Peirce Reservoir. You can find rubber trees and oil palms within the Reserve since the plot of land adjacent to it was formerly a plastic plantation. This area is not just known for its former rubber plantations but the existing Old Upper Thomson Road used to be Singapore’s first race track for racing cars. This can be a relatively simple walk, ideal for families with young children and the elderly. Start your walk near house no. 72 along Old Upper Thomson Road at the Casuarina Entrance. Shaded by the forest, the walk is pleasantly cool. There are plenty of informative signboards along the boardwalk that tell you more about the flora and fauna with this forest. The forest is home to a lot more than 900 flowering plants, 100 ferns and 250 animal species. You will encounter a wide range of wildlife from mammals to aquatic creatures and enjoy wonderful panaromas of waters surrounded with a luxuriant forest. Sometimes, around noon, you may see White-bellied Fish Eagles soaring in the sky and over the waters of the reservoir.
