Kilsby Sinkhole

Kilsby Sinkhole

Snorkelling the in the 60m deep crystal clear water is like exploring another world. It’s cavernous landscape is quite different to nearby Ewens and Piccaninnie Ponds, you feel like you are in a cave. Beginner snorkellers are looked after on this too.

What Can I See?

What Can I See?

  • No wildlife – unless you spot the introduced pet turtle or see the birds that live in the walls of the sinkhole above the water.
  • Amazing light show as rays of sunshine cut through the water to the bottom
  • Rock features
  • If you float on your back, amazing views looking up to the top of the sinkhole.
Snorkel Entry

Where & How do you get in?

You need to walk down a paved ramp then get down a couple of small ladders to reach the pontoon at water level. The ladders maybe have 4 rungs, so it is easy to put your gear down, climb the ladder and reach up to collect your things.

Best Season

Best Season

You can only snorkel at Kilsby during designated tours which generally run late morning and early afternoon. If you can do the snorkel on a sunny day you will see the sinkhole at its best as the rays of light shine through the water.

Tips

Potential Hazards

Despite the unique nature of this snorkel, it is relatively safe. The main issue is the cold and your 7mm wetsuit, gloves, boots and hood keep you warm. If you are not a strong swimmer, there are additional flotation aids available and the guides will look after you in the water.

How Busy/Crowds

Because access to the site is by tour only, you won’t have to worry about crowds of people. Snorkelling groups are limited to 8 people and there is plenty of room to spread out in the water.

Recommended Gear

If you have ever wanted to take pictures underwater, a sinkhole is the place to do it because the visibility is so good. If you have a camera, definitely bring it along. If you feel the cold, have something warm to wear afterwards.

Your guide will make sure it gets to the water safely as you make your way down the ladders.

Visibility

Like other sinkholes in the area, you can expect the visibility at Kilsby Sinkhole to be 50m+

About the Snorkel

We had already snorkelled at nearby Ewens Ponds and Piccaninnie Ponds so we couldn’t wait to tick off the third of the sinkhole snorkels around Mount Gambier.

Kilsby Sinkhole has some interesting history. It has been used for decades by the Department of Defence for developing deep water hardware and by the police for training their divers. Today, as well as being available for recreational snorkellers, divers and free divers, the water is also used to produce gin.

Unlike Ewens and Piccaninnie Ponds, you need to go down to get to Kilsby Sinkhole and there isn’t the greenery you get at the two sinkholes either. At Kilsby it has much more of a cave vibe going for it.

As we slid into the water we had the same rush as you do with all sinkholes at being able to see so far. The visibility is virtually unlimited, so you get amazing views to the bottom and off into the distance away from the main hole.

For us the highlight was seeing the sun break through the morning cloud and rays of light shine right to the bottom of the pool. It was like a laser show or theatre spotlight. You could swim into the beams and feel part of the show, it real was a spectacular and beautiful experience.

We had seen images of people swimming in the beams of light before our snorkel, but nothing beats actually being the person in light. It is a truly magical experience.
