Phu Phra is at Ban Kanaisa, Tambon Na Sieo. It is a small mountain with drawings of Buddha images from the U Thong period on the face of a cliff. They date from the 18th-19th Buddhist century, around the early Ayutthaya period. There is a fair to pay homage to the drawings every April for 3 days. To get there, take Highway No. 201 (Chaiyaphum-Phu Khiao) for 13 kilometres, then turn left onto the Na Sieo-Huai Chan road and drive for 6 kilometres.
