The river is worth a boat ttour both at day and night. You will see the historic district, former warehouses and a lot of restaurants and bars along Clak Quay and the Riverwalk. The latter is more peaceful and romantic. At night You have a wonderfully illuminated skyline including the voew of Marina Bay Sands Hotel. At Night You have a lot of reflections of the lights on the river which makes it look sparkling. Great place for a nightcap,
