Phu Hin Rong Kla National Park 
 
Lom Sak District is the starting point to go to Phu Hin Rong Kla to the west. As the route is quite steep, extreme care should be exercised in driving. Phu Hin Rong Kla is a popular destination located along the Phitsanulok and Phetchabun borders and offers exotic scenery. It was once the base of communists’ resurgents fighting against the government some twenty years ago.
