Diving and snorkelling
With countless sunken wrecks, diverse marine life and spectacular water-filled caves, South Australia's national parks offer some wonderful diving experiences. The clean, temperate waters provide ideal conditions to explore underwater life and year-round diving is possible with warm, calm days through summer and clear days in the winter.
The combination of sandy beaches, offshore reefs and small islands makes for breathtaking scenery above and below the waterline at Innes National Park. The Investigator Heritage Trail, off the coast of the park, has 26 shipwrecks dating from 1849 to 1982 that attract divers from all over the world. Sea life is also easily explored by reef diving and snorkelling around the jetties.
For those suitably qualified, the freshwater sinkholes of Piccaninnie Ponds Conservation Park are popular with divers. The water clarity is amazing, with visibility that can exceed 40 metres, making this one of the most visually spectacular underwater sites in South Australia. This is also a great snorkelling destination.
Another favourite freshwater diving and snorkelling site is Ewens Ponds Conservation Park. The remarkably clear waters make it easy for divers to spot pygmy perch, crayfish and galaxids.
With countless shipwrecks off the coast of South Australia, the state offers a wide range of fascinating diving trails. They can be found in many areas of the state - from near-city locations such as Port Adelaide to far-flung regional spots on the Yorke Peninsula and Kangaroo Island. The Adelaide Underwater Heritage Trail includes four shipwrecks off Gulf St Vincent.
Before diving or snorkelling these sites, you should check which qualifications and permits are required.
