If you're feeling ambitious, lace up for the 36-kilometre Coast-to-Coast (C2C) Trail that cuts across the island and links Coney Island in the northeast to Jurong Lake Gardens in the west. The trail – a challenging combo of roadside paths and park connectors – takes you through some of the best parks and nature reserves in Singapore like Bukit Batok Nature Park, Macritchie Reservoir Bishan-Ang Mo Kio Park, and Singapore Botanic Gardens. Look out for quarry lakes, parts of an old cemetery, rustic forests along the way.
