About 50 meters from the riverside of Kwai Noi River and 75 km away from provincial town is the Lawa Cave. It is the biggest cave of this area and the stalactites and stalagmites inside are very nice. Boat trips can be hired from Pak Saeng Pier or go there by road across the bridge at Ban Kaeng Ra Boed. Going there overland is a bit tricky. You have to cross the bridge a little bit southwards and find the dirt road to the cave.
