Reusi Sawan and Luk Seua Cave are in Somdej Pra Sri Nakarin Park on Petch Kasem Rd. diagonally opposite the Provincial Courthouse. You can walk from one cave through to the other as they are connecting caves; Reusi Sawan (Ascetic's Heaven) is the cave in front. Outside sits a figure of the monk Phra Reusi or the hermit.. Inside are stalagmites and stalactites, and meandering streams that trickle through the caves.
