Singapore's rural northwest is the closest the city-state has to country roads. This 65km loop runs from the city through Mandai (Singapore Zoo), past the Sungei Buloh wetland reserve and the Kranji War Memorial, out to Lim Chu Kang — a sliver of farmland, vegetable kampongs, and oyster sheds at the edge of the Johor Strait. Light traffic on weekend mornings, hawker breakfast at start, and Malaysia visible across the water.
