About this spot
Aer Bajo sits in the Lembeh Strait, one of the world's premier macro diving destinations. The site's black sand bottom attracts an outsized population of small, rare fish and invertebrates that hide nowhere else. Depths range from 5 to 20 meters, making it accessible to intermediate divers and a strong choice for photographers hunting for jawfish, gobies, and nudibranchs. The dive follows the contour of the black sand slope. Most action happens in the shallower sections where the substrate meets patches of rubble. Current is typically mild, but check conditions with local operators before descent. Night dives here unlock a different cast of characters—nocturnal critters emerge from the sand after dark. Lembeh's reputation rests on consistent finds of unusual species in compact areas. Aer Bajo delivers that same promise. Even divers who've logged hundreds of dives in the strait often spot something new. The site works year-round, though local knowledge of seasonal patterns is essential. Access requires a boat from Lembeh's main anchorages. Most divers book through established dive operators based in the strait. Bring a macro lens or rent one locally if serious underwater photography is your goal.
