Koh Rok Nok and Koh Rok Nai are two islands on the Andaman Sea that have coral reefs teeming with tropical fish. While snorkeling, you may encounter moray eels, sea turtles, multicolor nudibranchs and starfish. Set against a backdrop of limestone hills, Koh Talabeng is an ancient island and popular kayaking spot. Explore the caves that have freshwater pools, stalactites and stalagmites. You can also check out the caves at Koh Phee or Ghost Island. Take a longtail boat ride to Koh Kai, also known as Chicken Island. Stroll on the beach and make your way to the lookout point. Swim, snorkel or relax on the beach before sailing back to the mainland. Why not take a speedboat or ferry to the peaceful and tiny Koh Jum.
