Koh Tao and Koh Nangyuan Speedboat Day Tour Thailand Renowned for cerulean waters, colorful coral reefs and a myriad of vibrant fish, the small islands of Koh Tao and Kho Nangyuan provide excellent snorkeling day trip locations, away from the tourist crowds of neighboring islands. Begin the day with a convenient hotel pick-up and a pre-departure breakfast on the pier. Exploring the azure waters will work up an appetite for a beachside restaurant lunch before hopping back on board and heading to the emerald bays of Koh Nangyuan. Here you'll get the chance to explore the shallow reefs of one of Thailand's best snorkeling spots. As the day starts to cool, travel ashore to make the 10-15 minute hike to the viewpoint offering spectacular views of the sandbar-linked island below. Enjoy a swift boat ride back to Samui and a return to your hotel.
