A Weekend Hike at Khao Pla Ra, Uthai Thani

Little has been known about prehistoric cultures in western upper part of the central region of Thailand. Extant archaeological investigations in the area have revealed a wide variety of artifacts. However, knowledge about past people is still limited and relatively unexplored.

Uthai Thani province is located in the upper central region of Thailand and is located at the boundary between central, western and northern region. Traces of human culture and settlement since prehistoric times have been discovered in the province, evolving into larger communities over time. Other provinces located within the vicinity, such as Kanchanaburi and Suphanburi also share a similar past, including identical geographical features- mountains, rivers and forests. Therefore, we are able to find traces of prehistoric settlements through various ancient human features. Evidence of their early days living on mountain ridges and hunting to survive, to their migration to the plains, and their evolvement into a larger community in the modern-day society serve as clear indications of life and dynamism in the area since the beginning of time.

“Tham Prathun” cave in Khao Pla Ra is another perfect illustration of the livelihood and beliefs of those from over 3000 years ago. These stories are vibrantly told through colourful paintings on mountain ridges. Many of the paintings feature both human and various types of animals- dressed and adorned with quirky costumes, while displaying various gestures. These paintings are also a reminiscence of a prehistoric procession or ritual. The physical attribute of the mountain cliff, which slopes out to about 80 degrees, gives rise to a canopy which serves as a strong protection of the roughly 40 coloured paintings from the sun and rain.

On Saturday, 25 to Sunday, 26 June 2022, The Siam Society is arranging a weekend excursion to Uthai Thani province. This trip will serve as an eye-opening adventure to an ancient site and exotic landscapes once shared by past people at least 2000 years ago. Our trip includes a visit to a well-known prehistoric rock art site at Khao Pla Ra, museums housing archaeological remains, and other interesting sites in the area.
