Aldermens- Mooring Bay - Goat Island & Hauraki Gulf

Mooring Bay at the Aldermen is a really interesting contrast to the deeper outer sites. We love it for its sheer accessibility, especially when the weather kicks up elsewhere. It’s a calmer spot, mostly sandy, but don't let that fool you into thinking there's nothing here. We often find the sand flats hold some real treats – spotted stargazers buried with just their eyes peeking out, or a smooth skate gliding past like a shadow. The max depth of 17m makes it very relaxed, ideal for longer bottom times. We've seen fat red rock lobsters tucked into little ledges and schools of demoiselles flickering over the slight rises. Keep an eye out for the triplefins, especially the blue-eyed ones, darting between the smaller rocks. It's a fantastic place to just bimble around, practicing buoyancy, and really observing the smaller, often overlooked critters. Visibility averages a comfortable 15m, and being sheltered, it's a solid choice when you want a relaxed dive without battling much current.
