1. Umpherston Sinkhole
There might be 50+ sinkholes in Mount Gambier but nothing will prepare you for the beauty of the Umpherston Sinkhole. In 1886 when the once limestone cave’s roof collapsed, James Umpherston created the most beautiful garden in Australia.
You can walk right down into the garden and admire it from different perspectives. At night time the garden comes alive as hundreds of possums come out to eat.
It did remind us a bit of the famous IK Kil cenote in Mexico but we thought the Umpherston Sinkhole is better!
Mexico’s famous Ik-kil Cenote reminded us a little bit of the Umpherston Sinkhole.
2. The Blue Lake
Ticking off the top two attractions in Mount Gambier includes the Umpherston Sinkhole and The Blue Lake. The mind blowing Blue Lake is an absolutely incredible sight and is one of the four crater lakes around Mount Gambier.
It’s believed to be around 75 metres deep and stretches over a 1000 metres wide. One of the reasons why tourists comes to Mount Gambier is to witness the lake’s intensive cobalt blue colour which can only be seen during the summer months. It’s believed the lake changes from it’s usual grey colour when there’s a change in the water temperature.
Swimming isn’t permitted but it’s strongly advised to walk the 3.6km hike around the circumference of the lake to get a better understanding and perspective of this natural phenomenon in Mount Gambier.
3. But swim in Little Blue Lake
You might not be able to swim in The Blue Lake in Mount Gambier but you can at the Little Blue Lake which sites 11km south west of the city. It’s around 40 metres deep but there’s a great pontoon to spend a lazy summer day to enjoy.

5. Mount Gambier Cave Gardens
Best to visit the cave gardens first before you head over to Umpherston Sinkhole because although they aren’t as impressive, it’s still mind blowing to see something like this in the middle of the city.
There’s a sound and light show which takes place every night at the Cave Gardens and also the Farmers Markets from 9-12pm on Saturdays.
6. Hike Valley Lake
If you’re looking to do a short hike in Mount Gambier then try the 1.2km hike around Valley Lake which is definitely less crowded than the Blue Lake and a great quiet spot for the family to enjoy.
7. Scuba dive / Snorkel in the incredible Kilsby Sinkhole
There’s a platform at the bottom of the sinkhole for the divers to enter.
There are so many snorkelling, cave diving, cavern diving and technical diving sites around Mount Gambier that they easily give Mexico’s cenotes in the Riviera Maya a run for their money.
Mind blowing to think the entrance to this extraordinary sinkhole is at a sheep farm.
One standout is the Kilsby Sinkhole. Located on a sheep farm, this world renowned diving site has been used by the Navy and to train Police divers in the past.
The most interesting fact is when the sun rises, it completely lights up the entire cave as deep as 40 metres (you can actually dive down to 70 metres if you’re a qualified cave diver). You’ll be able to witness a spectacular light show as it dances around you. If you’re into scuba diving then put Kilsby Sinkhole on your bucket list right now.
