The discovery of 3,000 years old cave paintings was announced by archaeologists from the Fine Arts Office in May in 2020. Some of the depicted pictures are still visible and clear, while some paintings were damaged by limestone etching. According to archeologist Kannika Premjai, paintings describe humanlike figures with accessories on their bodies, hunting scenes with bow and arrow. Moreover, there is also an animal figure seems to be serow (a goat-like mammal found regionally) found among the drawings. In October 2020, more rock art was discovered in unmapped caves in Sam Roi Yot National Park, dating back to between 2,000 to 3,000 years ago.
