About Piccaninnie Ponds Conservation Park

One of Australia's most spectacular freshwater diving sites, Piccaninnie Ponds consists of a series of spring-fed clear pools connected by underwater passages to the Great Artesian aquifer. The main chamber — the 'Chasm' — drops to over 100m with extraordinary visibility. The water is so clear that the underwater formations are visible from the surface.
