HTMS Chang Wreck

Thailand's largest wreck, about 30 minutes by boat from Koh Chang. Open Water divers explore the tower, captain's cabin and gun turrets on the upper decks; the main deck (~20 to 23m) and sand at 30m suit Advanced/Deep divers, and full interior penetration needs wreck certification.
