Henry Head is a Sydney coastal reef dive in Kamay Botany Bay National Park, where sponge gardens, ledges, overhangs, and swim-throughs create an easy-to-read structure dive close to the La Perouse headlands. The site works well from land-based access near the lighthouse or as a guided boat dive, with the main planning focus on swell, timing, and how clear the water is on the day.
