Khao Sok National Park: Unmissable Highlights

Khao Sok National Park encompasses a 739-square-kilometer reserve of primary rainforest, ancient limestone karsts, and the man-made Cheow Lan Lake. This selection highlights the park's diverse geography, from the iconic Khao Sam Kloe rock formations to extensive cave systems like Diamond Cave. Visitors can explore deep-jungle trekking trails, navigate the Rajjaprabha Dam's turquoise waters, and access viewpoints overlooking the neighboring Klong Phanom mountains. The area serves as a critical habitat for rare species including the Rafflesia flower and diverse tropical wildlife.
