The official Singapore River Cruise charges S$25 for 40 minutes, but local bumboat operators near Clarke Quay offer similar routes for S$10-15. These are working boats that locals use, not tourist packages with canned commentary.

You'll see the same landmarks — Boat Quay, Marina Bay, colonial buildings — But with more authentic atmosphere and real working river traffic. Boats run frequently during daylight hours, no reservation needed. Just walk up to any operator near the water taxi stands and negotiate the fare first.
