One of the iconic pictures is from Overlap stone for sure. To be honest there is nothing else there except this giant stone but it was worth it :D
6. Elephant Kingdom
There are lot of elephant camps and sanctuaries in Thailand but I was interested in this particular one as they don't allow riding and these wild beast are allow to roam open. You can feed them, touch them and take a bath if don't mid getting dirty. They provide you grass and bananas to feed them, also have restaurant and toilet at the place.
