Singapore's water experiences are structured around one of the world's great natural harbours. The Singapore River bumboat tours — traditional wooden vessels that once ferried goods between the godowns and the anchorage, now offering guided sightseeing loops between Clarke Quay and the Merlion Park — provide the most accessible view of the shophouse waterfront. Sentosa Island cable car and ferry combinations, Marina Bay Sands skyline evening harbour tours, and the Southern Islands day trip ferry to St. John's Island and Kusu Island for snorkelling add further options. The Johor Strait ferry to Malaysia from the Tanah Merah Ferry Terminal, traditional bumboat connections to Pulau Ubin island (a last fragment of 1960s kampung village life), and Singapore Tall Ship harbour cruises extend the water geography considerably.
