The length of the river is 372 kilometers. This river's name means, "The Royal River," is the main river in Thailand. The source of the river is from the north, where it descends through the capital Bangkok, until it empties into the Thai bay. Actually the river surrounds the city from the West. After surrounding the city from North to South and empties into the Siam Bay, near the Bangkok port.
In parallel to its historic title, the city's legacy, the river is used for everyday use in the city. Bangkok's residents use the Chao Phraya as a central transportation line. Commute boats are efficient in Bangkok, sailing up and down the river non-stop, between set stops, this is without a doubt the more efficient and cheapest transportation in the city. Many stops are along the Eastern banks of the river.
The river is also used to tour tourists, for playing sports, and demonstrations. Some of the poorer neighborhoods on the river banks use the river for washing and bathing.
There are a number of bridges going across the river, considered the most important bridges in Thailand. Among them are the Rama VI Bridge, the longest train bridge in the country, the Rama VIII Bridge that is drawn on the 20 Baht bills, whose length is 2.45 kilometers, the Rama IX Suspension Bridge (the longest of its kind at 780 meters), and a mega-bridge that crosses the river twice and is one of the main transportation ways into the city. The last is the 658-foot-long Ferran Pin Clan Bridge.
Also, if you arrived to the river through Guidol, you are standing near the pier of boats heading for a tour around the Chao Phraya river and canals in town. This tour is totally worth going on, and creates a small window into the traditional lives of the temples around the river banks. From here you will also see a modern vibrant city that is built on its banks, through the floating markets and the world that is going on here, right on the water.
If you want to sail the river try getting here early in the morning. The line for boats during rush hour can be long and crowded, and waiting for a boat can take a long time.
