This scenic and flat 20-mile round-trip bicycle route follows the waterfront promenade that wraps around Tolo Harbour, which makes a ride an excellent way to combine an easy bit of exercise with sightseeing. Enjoy views of the eight peaks of the Pat Sin Leng mountain range as you pedal and soak up the ultramodern architecture of the Hong Kong Science Park. At the Tai Po Waterfront Park, climb the 105-foot lookout tower to snap photos of panoramic harbor and park views before heading back the same way you came. The full round-trip ride takes two to three hours, depending on how often you stop for photos. Join a guided tour, or go solo and rent bikes by the Shing Mun River at Sha Tin Park near the Sha Tin MTR station.
