Mandai Track 7 is a small road required to access Nee Soon Rifle Range, Upper Seletar Reservoir and Mandai Golf Course. Part of the track is adjacent to the Nee Soon Swamp Forest, our only primary freshwater swamp forest left in Singapore. This is one of the best and shortest trails to learn as a serious botanist from the large diversity of species spanning a primary swamp forest on one side and a secondary forest on the other, sprinkled with some cultivated and naturalised species around.
