    Passe de Tikehau, or Tuheiava, is Rangiroa’s quieter cousin, and for good reason. We love how Tikehau offers a gentler introduction to pass diving, particularly when the current comes in. It’s a shallow drift, mostly under 10 meters, so you get incredible light bouncing off the sandy bottom, illuminating the schooling fusiliers and triggerfish. You’ll spot giant squirrelfish lurking under ledges and often catch glimpse of the iconic unicornfish gliding by. We’ve seen it busy, but usually, it's a calm, easy drift, perfect for those building confidence in currents or anyone who just wants a relaxed, colourful dive. Keep an eye out for the yellowmouth barracuda schools, they’re dense here. We rate this dive highly for its consistent good visibility and the sheer number of small reef fish, even if the big pelagics are a less frequent show than in some of Rangiroa's other passes.

    Safety Notes

    Wreck site - avoid penetration without wreck diving certification. Watch for sharp metal and entanglement hazards.
