Acacia Bay
Why dive here
With 72+ marine species recorded in the area - including blue sharks, dolphins, hammerhead sharks, humpback whales and seahorses - Acacia Bay offers some of Goat Island & Hauraki Gulf's richest reef diving. Water ranges 14-22°C, warmest January, February, March.
Acacia Bay, tucked away in the Hauraki Gulf, makes for a straightforward dive, especially if you’re looking to get some practice in. We’ve found it’s a solid spot for honing buoyancy, given the silty patches if you stir things up. The underwater landscape is mostly rock wall, with a circular rock structure that divers built, which is a nice reference point when you’re navigating. Keep an eye out for freshwater crayfish nestled in the cracks, and you might even spot a rainbow or brown trout cruising by. It’s a good choice for newer divers or those simply wanting a relaxed dip to about 15 metres.
Safety Notes
