Despite being relatively unknown to most foreign visitors, Nakhon Sawan features a wide variety of attractions, from a celestial observatory to a large aquarium, as well as many natural attractions, including the largest swamp in Thailand, which contains many exotic species of bird and fish.
Nakhon Sawan Province, also known as Pak Nam Pho, is where the rivers Ping, Wang, Yom, and Nan converge and form the Chao Phraya River, the most important waterway in Thailand. Nakhon Sawan is in the lower northern part of Thailand between the North and the Central Regions and as such, it is regarded as the doorway to the North and the hub of transportation in the lower North.
Nakhon Sawan is located in the lower north of Thailand and is often referred to as “Pak Nam Pho” a name that refers to the big Pho tree that is located at the mouth of the Chao Phraya, the most important river in Thailand. In fact, Nakhon Sawan is located at the confluence of four rivers: the Ping, Wang, Yom, and Nan, all of which flow into the Chao Phraya. In addition to the mouth of the Chao Phraya, Nakhon Sawan is home to a number of unique attractions: Nakhon Sawan Tower, atop Khiriwong Temple Hill, contains a shop selling locally made products and features a rooftop viewing platform that overlooks Nakhon Sawan Municipality and has a number of telescopes for visitors interested in astronomy and celestial observation; Bueng Boraphet Aquarium, built in the shape of a traditional Chao Phraya commercial transport boat, was built to commemorate the King’s 80th Birthday and features more than 30 fish tanks, including a 24 meter-long main tank exhibiting more than 100 kinds of freshwater tropical fish; and Bung Boraphet, the largest freshwater swamp in Thailand, which is home to nearly 150 species of animals, including the white-eyed river-martin and tiger perch, and hosts a large number of migratory waterfowl from November to March.
