Phu Pha Ya Archaeological Site is located north of Ban Na Charoen, in Dong Ma Fai Subdistrict, Suwannakhuha District, Nong Bua Lamphu Province. It is a limestone mountain separated from the Phu Phan range, characterized by cliffs and rock shelters that served as prehistoric dwellings and art sites. The site has been officially registered as a historical site by the Fine Arts Department.

The most significant evidence at the site is the ancient rock art on cave walls and rock shelters. Most of the paintings use red pigment and date back 2,000–3,000 years. They depict human activities such as standing, walking, and hunting, as well as forest animals like cattle, deer, crocodiles, and reptiles. Additional motifs include handprints and geometric patterns, reflecting the beliefs and culture of ancient communities. These discoveries are crucial for studying the history of upper northeastern Thailand and connect with similar archaeological sites in the region.

Beyond its archaeological importance, Phu Pha Ya offers beautiful natural scenery due to its limestone cliffs and rich forests. The site is suitable for eco-tourism and nature study. The name "Phu Pha Ya" originates from local lore, which says that large tobacco plants and various medicinal herbs once grew on the mountain, symbolizing its historical abundance of flora.
