Hin Phad
Vaguely resembling Koh Samui's Overlap Stone, this massive, gravity-defying rock hides in Surat Thani's Khiri Rat Nikhom district in the middle of the rainforest. Drive a car or ride a scooter to this rock, and you'll find yourself surrounded by nothing but rubber trees, cacti, and the calming sounds of coucal birds and the nearby waterfall.
