Why dive here
With 158+ marine species recorded in the area - including blacktip reef sharks, blue-spotted stingrays, mobula rays (devil rays), whale sharks and pufferfish - Koh Thong Kaeo / เกาะทองแก้ว offers some of Gulf of Thailand's richest diving. Water ranges 28-31°C, warmest April, May, June.
Koh Thong Kaeo is a shallow, gentle spot in the Gulf, perfect for getting back in the water or doing your first few dives. We often find ourselves drifting over a mix of sand and scattered coral patches, watching for gobies and their pistol shrimp companions. Look closely in the nooks and crannies of the small rock formations and you might spot a juvenile lionfish or a moray eel peeking out. It's not a dramatic wall dive, but for easy, relaxed bottom time, especially if you’re still getting comfortable with your buoyancy, it's a solid choice.
