Though much of Singapore's original vegetation has been cleared to make way for urban development, Bukit Timah Nature Reserve has remained relatively undisturbed from its pre-colonial state. Best known for its tallest hill, the 164-meter Bukit Timah, the reserve is also amazingly rich in biodiversity with about 40 percent of the country's flora and fauna, including the long-tailed macaque (monkey). The reserve was officially declared an Asean Heritage Park in October 2011.
