    Little Cave Bay often gets overlooked for the bigger, flashier caves around the Poor Knights, and that’s a shame. We think it’s a brilliant spot for a relaxed second dive or when the wind is kicking up a fuss elsewhere. The name comes from a small crevice in the corner – don't expect a grand cathedral, but it’s a nice little poke-around, good for finding some shy triplefins. The real magic here is the light. On a sunny day, those golden shafts slicing through the kelp forest are just something else, especially when you’re floating above the sandy patches. You’ll find schools of spotties and demoiselles swirling in the shallows, and we’ve often seen snapper cruising along the reef edge. Keep an eye out for stingrays in the sand. It’s a gentle slope down to about 19 meters, easy to navigate, and generally calm, making it a great place to refine buoyancy or just drift and soak it all in. If you want high drama, go elsewhere, but for pure, serene diving, Little Cave Bay is our quiet favourite.
