Koh Nang Yuan is a stunning small island located off the northwest coast of Koh Tao. It consists of three rocky islets connected by a picturesque white sandbar that emerges during low tide. The island is famous for its turquoise crystal-clear waters and excellent snorkeling spots with colorful coral reefs. Climbing to the viewpoint offers a spectacular panoramic view of the three islands and the sandbar. Plastic and cans are prohibited on the island to protect its natural environment.
