This protected marine park includes over 40 islands varying in size and shape with tropical rainforests and beautiful beaches. Access to the park is limited to the various licensed tour operators and boat rental companies in Koh Samui and Koh Tao. The tours vary which islands they will visit as well as different activities, such as snorkeling, hiking, caving, kayaking and staying overnight. This is a great way to explore the islands and enjoy some beach time.
