The Khao Ngoo Stone Park is a limestone mountain that has since been developed into a public park, featuring a scenic drive that winds around the hills. It is also an important archaeological site, as the area surrounding the park is home to the Khao Ngoo cave complex, which is considered a significant historical location. Each cave contains rock engravings related to Buddhism that date back to the Dvaravati period. One notable site is the Rishi Cave at the foothill, close to the Buddha statue in the posture of "Leela" (the Buddha in a reclining position), which holds significant Buddhist importance. Inside this cave, there is a sculpture of the Buddha seated with his feet elegantly carved from the rock, depicted in the teaching posture or Vitarka Mudra, consistent with the Buddhist art style of the Dvaravati period. Additionally, there are several sandstone Buddha statues dating from the Ayutthaya period to explore.
