Why dive here
With 236+ marine species recorded in the area - including blacktip reef sharks, manta rays, mobula rays (devil rays), pygmy seahorses and sea turtles - Alyui Bay offers some of Raja Ampat's richest reef diving. Water ranges 29-30°C, warmest October, November, December.
Alyui Bay, tucked into the western side of Waigeo, is where we head when the mission is small stuff. Forget the big pelagics here; this is critter territory. We’ve spent hours finning slowly along its walls and slopes, spotting pygmy seahorses clinging to gorgonians and ghost pipefish swaying in the current. It’s a macro photographer's dream, a place where patience really pays off. The max depth usually hovers around 25 metres, making it approachable for most divers, though keeping an eye on your buoyancy is key when you’re hovering over delicate subjects. Currents can pick up, especially near the mouth, so it’s not always a completely placid drift.
Safety Notes
Strong currents typical this month (avg 40 cm/s). Good buoyancy control essential.
