The Tree Top Walk at MacRitchie Reservoir takes you through the different stages of a mature secondary forest. It’s the first of its kind in Singapore and South-East Asia. The bridge part rises as high as 27 metres, and you can see as many as 80 bird and eight reptile varieties, and 18 rare species of trees. National Parks Board calls it one of the best hiking routes, but be sure to wear the right shoes; it’s graded moderate-to-difficult. Getting to the bridge, and walking it and back is a 10.5km journey. And, oh, beware of falling branches – a man was killed by one earlier this year after a heavy rainfall.
