Chao Phraya River in Bangkok

Like all urban rivers, the history of the Chao Phraya is intertwined with the city it flows through. The original site was chosen by early settlers because of its fertility and abundant fish. Later King Taksin, after the fall of Ayutthaya to the Burmese, located his new capital here, on the western banks today known as Thonburi.

In 1782 King Rama I, finding the eastern banks more favourable, founded modern Bangkok and celebrated the occasion by building some of the world's most beguiling temples. Later still the canals it feeds became famous, earning Bangkok its 'Venice of the East' epithet. And, meanwhile, eminent Western authors like Maugham, Conrad and Coward were singling out the Chao Phraya as one of their favourite spots in the Far East.

'Tourist Boats' are another option, offering unlimited trips to nine prominent piers for a 150 baht flat fee (service hours: 09.30 - 15.00 daily). Not a bad deal if you plan to do a lot of hopping on and off over one day, want more comfort and the sites to be pointed out to you. Bear in mind though – these run every 30 minutes while the public lines used by locals typically run every 15 to 20 minutes. Other options for exploring the river include hiring a long-tail boat (usually includes trips down the city's canals), a river cruise or dinner cruise. All give a different perspective on this fascinating river.

Phra Arthit Road runs parallel to the Chao Phraya River, stretching from Phra Sumen fort to Thammasat Universty.

The nearest river pier is Phra Arthit Pier.

Thewet is scintillating. People come here to make merit by releasing fish or to feed the school of frenzied catfish scraps of bread. There's also a ramshackle yet photogenic wet market, and the Royal enclave of Dusit nearby. The nearest river pier is Thewet.
