At Piccaninnie Ponds you can snorkel across the top of The Chasm and peer down into the dark depths below. The crystal clear waters have been slowly filtering through the limestone and forming the Pond's features over thousands of years. The freshwater rising to the surface under pressure has eroded a weakness in the limestone to form The Chasm, with its white walls covered in delicate green algal growth contrasting with the dark depths below.
This same process has formed the large underwater cavern known as The Cathedral because of its majestic white walls of sculptured and scalloped limestone. With visibility that can exceed 40 metres, this is one of the prettiest and most spectacular underwater sites in the Limestone coast.
A diving permit/timeslot system operates to protect this delicate area. Dive bookings can be made by phone or in person at Department of Environment, Water and Natural Resources (DEWNR) Mount Gambier office and must be confirmed with lodgement of a Cave Diving Permit/Indemnity form (available from the DEWNR Mount Gambier Office) and payment, prior to the dive. Snorkel permits are also required.
