Why dive here
With 391+ marine species recorded in the area - including barracuda, blacktip reef sharks, grey reef sharks, humpback whales and orcas - Blanche Wall offers some of Iron Bottom Sound's richest wreck diving. Water ranges 29-31°C, warmest January, April, December.
Blanche Wall stretches a good three kilometres, about twenty minutes southeast of Papatura, and makes for a solid dive. We've dropped in here at various depths, but usually aim for around 25 metres, sometimes a bit shallower to check out the top of the wall. Keep an eye out for turtles tucked into the crevices, they seem to appreciate a good snooze spot. You'll likely spot grey reef and blacktip sharks cruising by, plus the usual reef suspects like triggerfish and clownfish. Currents can be a bit shifty, pulling in both directions with the tide, so it’s worth asking your guide about the conditions before you jump. It’s a good choice for divers who appreciate a long drift along a coral wall without too much fuss.
