About

Discover the spring-fed limestone ponds at the Ewens Ponds Conservation Park by snorkelling along the shallow channels or scuba diving into the ponds.

The channels connect three basin-shaped ponds which are approximately 10 metres deep. The clarity of the water enables plants to grow underwater to a depth of about six metres. Some of these plants are not found growing fully submerged underwater anywhere else in the world.

Opening hours

Open 24 hours a day, seven days a week.

Snorkelling and diving

One hour time slots are available daily, 5:00 am - 12:00 am (midnight)*.

*Ewens Ponds are closed annually for snorkelling and diving from 1 September to 30 November (inclusive).

Closures and safety

This park is closed on days of Catastrophic Fire Danger and may also be closed on days of Extreme Fire Danger.

Getting there

Assistance dogs

Assistance dogs are permitted in most public places and are therefore welcome in South Australia’s parks and reserves. Assistance dogs must be appropriately restrained on a lead and remain under your effective control at all times while in a park or reserve.

As per the dogs in parks and reserves policy, if the dog is not an accredited assistance dog, they must be trained to assist a person with a disability to alleviate that disability and meet standards of hygiene and behaviour appropriate for a dog in a public place. However, refusal may be given if the person with the disability is unable to produce evidence the dog is an assistance dog with the appropriate training.

Before taking your assistance dog into a park that does not normally allow dogs, it is highly recommended that you contact us so we can provide you with the latest information on any potential hazards within specific parks that may affect your dog. Please contact the park via the contact details provided under the contact tab or call the information line on (+61 8) 8204 1910.

Traditional owners

Aboriginal peoples have occupied, enjoyed and managed the lands and waters of this State for thousands of generations. For Aboriginal first nations, creation ancestors laid down the laws of the Country and bestowed a range of customary rights and obligations to the many Aboriginal Nations across our state. 

There are many places across the State that have great spiritual significance to Aboriginal first nations.  At some of these places Aboriginal cultural protocols, such as restricted access, are promoted and visitors are asked to respect the wishes of Traditional Owners.

In places where protocols are not promoted visitors are asked to show respect by not touching or removing anything, and make sure you take all your rubbish with you when you leave.

Aboriginal peoples continue to play an active role in caring for their Country, including in parks across South Australia.
