Explore Koh Samui

Get to know Koh Samui with Viator

With rainforest-cloaked mountains looming over white-sand beaches and coconut groves, Koh Samui is every bit the picture-perfect tropical island escape. Thailand’s second-largest island has enough luxury beach resorts, yoga retreats, and spas to tempt travelers away from the party hubs of the surrounding islands. But it’s not all about rest and relaxation here; Koh Samui also has several sacred temples, world-class snorkeling and scuba diving, and very lively nightlife.
