Namtok Chet Sao Noi Waterfall National Park is one of the most popular and most visited parks in the country by local tourists. It is not known much by the foreign tourists and overlooked as most foreign tourists prefer to get to nearby Khao Yai National Park.

The park is located between Saraburi and Nakhon Ratchasima provinces. Muak Lek River which flows through the falls is the natural border between both provinces at the area of the falls. Crossing one of the bridges from east side, or swimming to the other side and you will be on Nakhon Ratchasima Province.
