At 57-hectares and with a range of natural and green habitats, Kranji Marshes is Singapore's largest freshwater farmland. The nature reserve is home to 170 species of birds, 54 types of butterflies, and 33 different kinds of dragonflies. It was cultivated since the ’70s when the Kranji reservoir was dammed, forming a wild diversity of terrains such as marshland, grassland and secondary forests.
The 10.65-metre-tall Raptor Tower offers a panoramic view of the surrounding marshes. Educational boards are placed around the open-air observatory deck of the tower, helping the eagle-eyed identify birds and pick out landmarks such as the Moorhen Pond and the BBC Shortwave relay station in the distance. From November to March, you can also catch raptor birds – otherwise known as birds of prey – that include migratory visiting species such as the Black Baza and Japanese Sparrowhawk.
