Guided Fun Dives – Explore the Underwater World of Koh Chang
Fun Diving in Koh Chang, Thailand – Your Gateway to the Gulf of Thailand
Looking for fun diving in Koh Chang? Our daily guided boat dives take certified divers to 13 spectacular dive sites around Koh Chang and the Gulf of Thailand. From shallow coral gardens perfect for relaxed diving to the iconic HTMS Chang wreck – Thailand's largest shipwreck at 100 meters long and 30 meters deep – every dive offers something unique.
Scuba diving in Koh Chang means exploring pristine Mu Koh Chang National Marine Park reefs, dramatic underwater pinnacles, and multiple wreck dive sites. Our fun dive trips are designed for certified divers (Open Water and above) who want hassle-free, small-group diving experiences in Thailand's Eastern Gulf. Expect vibrant soft corals, barracuda schools, giant groupers, reef sharks, turtles, and with luck – whale sharks during season (November-May).
Each boat diving day trip includes 2-3 guided dives, full scuba equipment, experienced multilingual dive guides (max. 5 divers per guide), lunch, drinks, and hotel pickup from selected areas on Koh Chang's west coast. Whether you're after wreck diving adventures, macro critter hunting, or simply relaxed reef exploration – Koh Chang's diverse dive sites in the Gulf of Thailand deliver world-class underwater experiences at excellent value.
Worry-free booking: Simply reserve online – we verify your certification in advance (CMAS divers send a photo). On dive day, we handle hotel pickup, equipment setup, and site selection based on conditions. Just bring your certification card, dive computer, and sense of adventure!
