Piccaninnie Ponds Conservation Park

Piccaninnie Ponds Conservation Park is a coastal conservation park near Port MacDonnell in the District Council of Grant, south-eastern South Australia, about 30 km southeast of Mount Gambier. It protects a Ramsar-listed karst wetland system of crystal-clear freshwater springs, ponds and the deep limestone sinkhole known as The Chasm. Renowned for snorkelling and cave diving visibility exceeding 30 metres, it also features boardwalks, coastal dunes and diverse wetland habitats.

Visitors can expect a coastal karst landscape with exceptionally clear freshwater ponds fed by limestone springs, fringed by reeds, wetlands and coastal dunes. A boardwalk and viewing platforms allow observation of the ponds without entering the water. The main visitor activities are snorkelling in the First Pond and licensed cave diving in The Chasm and The Ponds, where underwater visibility is very high. The park is natural and undeveloped, with walking trails, birdwatching and photography opportunities.
