Bangkok Boat Travel Tips
Instead of using the air-conditioned boat, enjoy the panoramic views of the river on the deck of a double decker boat while traveling between the city's main attractions conveniently. Simply get a day pass for the Chao Phraya Tourist Boat.
As traffic in the city center is often jammed, public boats can be used as a reliable way to get to the most popular Bangkok river cruise departure points on time.
