White Beach, Koh Tao

White Beach on Koh Tao provides the finest diving-and-beach combo in Thailand. Sai Nuan Beach, along its southern coast, features 800 meters of powdery white sand with calm clear waters where visibility reaches 20 meters year-round. The gentle gradient means the water stays waist-deep for 50 meters, perfect for beginners. Compared to the bustling Patong Beach where traffic noise intrudes, here the only sounds are lapping waves and birdsong. Buoys mark three snorkel trails, each taking 15 minutes to traverse.
