A great way to experience Singapore is from the water. River Explorer Boat Tours launch from the eastern end of Boat Quay near the Fullerton Hotel. The glass-walled boats have open back decks for easy viewing and come with a guide to point out all the cool landmarks along the way. The tour takes you down to Clarke Quay, along the river, and out into Marina Bay. Call 65/6339-6833 for tickets or stop by the booth.
