is in Tambon Thon Hong. It is 30km from the city on Highway No. 4016 on the same route as Phrom Lok waterfall. However, it is at Km. 26 and then going on a left-hand road for 3km more. The source is also from Khao Luang. This waterfall has 9 levels, which are Nan Chong Sai, Nan Bang Bai, Nan Mai Phai, Nan Sua Phan, Nan Buppha Sawan, Nan Hin Kong, Nan Hua Chang, Nan Sai Kwat Lan, and Nan Fa Faet. The surrounding area is still a dense jungle. Both sides of the falls are covered with betel gardens. The locals call the betel Phlu Pak Sai because of its hot flavor and sweet scent. The view of Khao Luang is best viewed from here.
