Tour Ang Thong National Marine Park

Both Koh Samui and Koh Phangan are part of this breathtaking archipelago of 42 islands. If you take only one tour while you're on vacation in this area, make it a sightseeing tour around Ang Thong. Many tour companies offer one-day packages, and you can typically arrange these through your hotel or guesthouse.

Most include a boat tour through the islands with stops for snorkeling, kayaking, and hiking to viewpoints, where you can admire this amazing island chain. Limited accommodation is available in the park, so plan your time well if you want to return to the main islands for the night. Be sure to keep your camera handy and find a spot above deck, because you won't want to miss the breathtaking photo ops.
