Geologically, the park features distinctive sandstone formations shaped by long-term erosion, creating layered cliffs, rock corridors, and natural cavities. Some formations resemble caves, locally known as Tham Phra (Buddha Cave) and Tham Phaya Naga, names derived from local beliefs and folklore.Inside the park is the sacred “Luang Pho Ong Dam,” a seated Buddha image in the Maravijaya posture enshrined beneath a natural rock shelter. It serves as a spiritual center for local communities and visitors, and the area is also used for meditation and religious ceremonies on important Buddhist days.

Pha Sawoei viewpoint is one of the key highlights, offering panoramic views of mountains and surrounding forests. It also holds historical significance, as it is believed to have been a resting site during a royal visit by King Rama IX while touring northeastern Thailand.In terms of tourism, the best period to visit is from the rainy season to early winter (July–November), when the forest is lush and green, and during winter (November–February), when the weather is cool and comfortable for hiking and sightseeing.The internal trail system consists of natural walking paths and stone steps, allowing visitors to follow a circular route connecting major attractions such as the rock plateau, Luang Pho Ong Dam, Tham Phra cave, and Pha Sawoei viewpoint, integrating nature, spirituality, and local culture into a single experience.
