Tham Kaeo is located within the compound of Wat Tham Kaeo. The cave is similar to a hall deep inside the mountain with the chilliness and humidity throughout the year. Electricity is utilised inside. From the entrance, there is a path leading to the lower ground where a Buddha image is enshrined. Also, the stalactites on the wall create a dazzling reflection of light. There is a Buddha image and Luangpu Sot image in the cave. The right side has a room with glass walls and floor tiles. The left side has stone pillars and a bat cave. In case of having a high-power flashlight, bats will be seen. To get there: From Amphoe Phakdi Chumphon, take Highway No. 2359 for 9 kilometres to the north. At Ban Sap Charoen, turn left and go further for 5 kilometres.
