One of the wackiest tours in Singapore, the DUCKtours is a fun way to check out the surroundings. Climb onto a converted war vessel at Suntec City, and set out on an exploration on road and water! The entertaining crew and interesting captain make sure you never know just what to expect next; you could be ambling down a road, tearing through woods or sailing along the water. Find out about the Harbor Tour, Civic District and the Singapore Heritage Tour. Tours depart hourly and the last one leaves at 6p. Check the website for details.
