Koh Chang, which resembles an elephant in shape, is the largest island in Ranong Province. Traveling to Koh Chang is just as easy as going to Koh Phayam. You can take the same boat from the municipal pier at Pak Nam in Mueang District. Most tourists start their journey from the Ranong bus terminal, where you can catch several songthaew routes. Any songthaew that indicates "Koh Chang" or "Koh Phayam" will take you there.
