Loei Dun, Phetchabun

Loei Dun is located in Ban Huai Kapo, Lak Dan Sub-district, Nam Nao District. It features a sandstone formation in the middle of the Loei River that has been eroded over time, creating numerous small and large holes, resembling the famous Sam Phan Bok. This stunning natural formation is a result of natural geological processes. Loei Dan is also a natural and geological tourist attraction, partially designated as part of the Phetchabun Geopark. It is an ideal destination for both tourism and nature education.
