Long Tail Boat on Chao Phraya River
If the Express Boats are like a bus, then the Long Tail Boats are like a taxi. Hire one just for yourself, and despite their size they can safely hold only one or two passengers, and be transported at speed along the river to any destination in the city.
While the long tail boats are not metered there are set fees, but visitors to Thailand should be sure to agree on the price in advance.
