Piccaninnie Ponds
A karst spring of extraordinary clarity, with the Cathedral chamber and a chasm beyond 100 metres.
Piccaninnie Ponds is a karst spring system near the Victorian border, fed by groundwater filtered through limestone and known for clarity that can exceed 40 metres.
The main features are the First Pond, the Cathedral — a white limestone chamber — and the Chasm, which descends beyond 100 metres.
Access is permit-controlled and requires appropriate CDAA qualification for the deeper and overhead sections. Snorkelling permits are also issued for the shallow areas.
