Ewens Ponds Conservation Park

Ewens Ponds Conservation Park is a protected spring-fed wetland near Eight Mile Creek in the District Council of Grant, South Australia, about 25 kilometres south of Mount Gambier. Proclaimed in 1976, it preserves three crystal-clear limestone spring ponds connected by shallow channels. Renowned for exceptional underwater visibility up to 80 metres, the ponds support rare aquatic plants and fish. The park is a popular site for snorkelling and scuba diving in cool, constant-temperature waters.

Visitors can expect three interconnected, crystal-clear freshwater ponds fed by limestone karst springs, surrounded by native vegetation and wetlands. A walking trail with viewing platforms follows the ponds, allowing sightseeing and photography without entering the water. The main visitor experience is in-water snorkelling in Pond 1 and scuba diving in Ponds 2 and 3, with exceptionally clear, cool water revealing aquatic plants, fish and limestone formations. Facilities are low-key and natural, focused on conservation and low-impact recreation.
