MacRitchie Reservoir is part of the Central Catchment Nature Reserve located in the heart of Singapore. The treetop walk connects two of the highest points in MacRitchie Reservoir. The bridge is 250m long and gives you a birds eye view of the forest canopy. Singapore is a bustling city full of skyscrapers but you would never imagine it from your viewpoint on the bridge. Not a single building is visible from the bridge, just trees, plants, and birds. Closed on Mondays.
You can start your walk from either MacRitchie Reservoir Park (Route 3) or Venus Drive (Route 6).http://www.nparks.gov.sg/cms/index.php?option=com_visitorsguide&task=attractions&id=64&Itemid=73
