Trail: Old Upper Thomson Road

Old Upper Thomson Road

Old Upper Thomson Road is a historic, winding road famously known for hosting the Singapore Grand Prix (1961–1973) and for the infamous Devil's Bend turn. Formerly a rural area with 1910s kampongs and plantations, it was a major transit route that has now transformed into a tranquil nature corridor adjacent to Thomson Nature Park.
