7 Reasons Khao Sok Should Be Added to Your Thailand Itinerary

Khao Sok is famous for its staggering limestone mountains (also called karsts), and some rise as high as 3,000 feet tall! They're incredibly unique, a result of a vast geographic shift in tectonic plates over 60 million years ago that lifted and folded the limestone formation. And trust me, we're grateful to Mother Earth on this one, because they are absolutely stunning — pearl white crystals that reflect in the sun, covered with dense vegetation, and jetting steeply from the jungle floor or river straight into the sky.
