The Chao Phraya River (or Mae Nam Chao Phraya) runs north to south through Thailand, whose most notable and densely populated cities lie along the river's main tributary.
In Bangkok, the Chao Phraya is a major transportation artery. A vast network of ferries and water taxis, known as long tails, ferry locals and tourists up and down the river, connecting with the city's main sights. For many, these boats are the preferred way of getting around Bangkok, whose streets are often choked with traffic.
Several boat lines compete for business on the river and its canals and you’ll find variations in price and distance traveled. If you start at Tha Sathon (accessible via sky train at Saphan Taksi), you'll chug sedately past (or be able to disembark at) Chinatown, Wat Arun, Wichai Prasit Fort and the Grand Palace.
There’s no denying it - the Chao Phraya is a murky and sometimes smelly river, but even a short boat trip along it gives you a fresh perspective on the city.
