Lembeh Bay is probably one of the best known muck diving locations on the planet. There are so many sites and the local guides always seem to know who is spawning what at each site. I would not catalogue the dives as ‘exploration’ but they definitely give you a chance to see some very rare critters doing some pretty unusual things. I have only made ten dives in Lembeh but definitely plan to camp out there for longer periods once I retire. It is a UW photographer’s paradise with very knowledgeable staff/guides. Diving Lembeh is a rich experience you won’t forget.
The best critter season in Lembeh is April to October, probably due to a seasonal drop in water temperature.
