The Lava Fields are exactly what they sound like – a sprawling underwater landscape shaped by the 1905 eruption, now softened by a century of ocean life. We love how the dark, undulating basalt rock creates these natural canyons and swim-throughs, all just a few metres deep. It’s like diving through a submerged, ancient maze. Our favourite part has to be the light play. Sunlight filters down through the shallow water, bouncing off the sandy patches and illuminating the bowl corals that have colonised every available surface. Keep an eye out for the giants here: huge spider conches slowly traversing the sand, and we’ve spotted humpbacked conches settled in the crevices too. Blackfish often dart between the rocks, and it's a calm spot, perfect for new divers to practice their buoyancy without worrying about deep drop-offs or strong currents. The coral hind and silver squirrelfish are pretty common, but it's the sheer architectural beauty of the lava formations that really makes this place special. We’d suggest going in the morning; the water tends to be clearest, and the low sun casts long, dramatic shadows.
