Why dive here
With 369+ marine species recorded in the area - including barracuda, bull sharks, humpback whales, seahorses and sea turtles - Ugan offers some of Kerama Islands's richest diving. Water ranges 22-30°C, warmest July, August, September.
Ugan often gets overlooked for flashier Kerama spots, but it’s a solid intermediate dive. We find the main attraction is a series of small swim-throughs and overhangs at around 12-15m, often revealing resting reef sharks or schooling glassfish. It’s a comfortable depth, making it good for extending your bottom time and working on buoyancy in tighter spaces. If you’ve done the more famous sites and want something a little quieter, Ugan is a good choice.
