Ewen Ponds Conservation Park consists of three large freshwater springs, each around 10 metres deep, connected by a series of shallow channels.
Unlike Piccaninie Ponds, famous for its underwater caves, the main attraction here is incredible visibility up to 80 metres.
It is popular for snorkelling and scuba diving.
With the water temperature a chilly 10-15 degrees, a thick wetsuit is recommended.

The writer, David Harasti, says: “The highlight of diving in the ponds is the visibility! The first time I put my head underwater at Ewens Ponds I was shocked; the water was so clear it felt like I was diving in air. It is not uncommon to be able to see from one side of the pond to the other, a distance of over 80 metres. The other highlight is the growth as you drift through the two channels – it is a fantastic experience.”
We didn’t go diving, but there’s a lovely walk from the first pond to the third, which the kids enjoyed.
