Orai Tong Cave is a limestone cave in a steep mountain that extends from north to south of Sutton and is about 40 meters long and 25 meters wide. Three sea crevices indicate that the cave was affected by sea raids, in addition to the presence of some sea mollusk shells on the floor of the cave, and some ancient human and animal bones were found in the cave, including rhinos, zebras, cows and pigs.
