The Origin of the Chao Phraya River
The Origin of the Chao Phraya River is the point where the Ping and Nan rivers converge at Tambon Pak Nam Pho in front of the dam in the city.  Here, one can clearly distinguish the difference between the two rivers.  The Nan River is reddish in color while the Ping River is somewhat green.  They flow to form the Chao Phraya River, the most important waterway of the country.  The Chao Phraya flows past several provinces before going through Bangkok and ending into the Gulf of Thailand in Samut Prakan.  It is about 370 kilometers long.  The best place to view its origin is at the Chao Pho Thepharak-Chao Mae Thapthim Shrine.

Tourists can take boat rides to view the scenery on both banks and pay homage to Luang Pho To Buddha image at Wat Pak Nam Pho (Wat Thong Thammachat Nua).  Boats can be hired from Chao Phraya Pier.
