Si Dit waterfall is located in Tambon Nong Mae Na, Amphoe Khao Kho, Phetchabun. It can be reached from Highway 2196, turning west onto Highway 2325 at Km17 and on another 10 kilometers where it is signposted on the right.
The waterfall (namtok) is a large single-tiered waterfall, where water flows throughout the year. The area was once a stronghold of members of the Communist Party of Thailand, who went into hiding in the jungles of Phetchabun. Noteworthy is the nearby waterfall-powered rice mortar, used by CPT members whilst living in the forest. It was constructed by university students with technical skills who joined the Communist Party.
Opening hours are 7.00 am-5.00 pm daily.
