Located in South Australia, Mount Gambier is not only the perfect stop off when driving between Melbourne and Adelaide but it should be a destination that’s on your Australia bucket list.
There are hundreds of natural geological wonders that make Mount Gambier absolutely mind blowing.
Here’s the reasons why.
Did you know Mount Gambier actually sits right on top of an inactive volcano? When we first heard about this magical city, we knew we had to visit which coincided with our road trip from Sydney to Adelaide via Melbourne.
From huge sinkholes, a lake that turns bright blue in Summer and diving spots that will give the cenotes in Mexico a run for its money Mount Gambier is Australia’s secret gem.
Where is Mount Gambier?
It’s the second most populated city in South Australia with nearly 30,000 residents and sits right in the middle of Adelaide (4.5hours away) and Melbourne (5 hours away). When we visited, we had come from 40C heat in Melbourne to a chilly temp in Mount Gambier. Although the city isn’t on an elevation, the temperature can be cooler.

20 things to do in Mount Gambier
Pin below to save for later.
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.
Take your swimmers with you to The Little Blue Lake!
4. Echo Farm
One of the top attractions in Mount Gambier is the family favourite Echo Farm. This old style farm experience allows visitors to go on a self guided walk around the 17 acres.
It’s home to animals such as; pigs, emu, sheep, cats, geese, wallabys, chickens and more. This is a great farm which allows you to experience the authentic Australian farm life in a natural environment.
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.

17. Snorkelling / Scuba diving in Ewen Ponds Conservation Park
There are three ponds within this sinkhole with channels between them all, and only 10 metres deep so perfect for diving or snorkelling. What makes Ewan Ponds so unique is that the water is unbelievably clear and has been filtered through the rock from the limestone for thousands of years.
It also maintains a constant 16C all year round and because it’s so clear, it’s also one of the only places in the world where you can see some land plants growing under water. It’s also home to the endangered Ewens Pygmy Perch fish which can only be found in this pond, anywhere in the world.
18. Drink wine at Katnook Estate
Spend the afternoon wine tasting at the popular Katnook Estate in the Coonawarra region. They have a huge selection of Katnook reds and whites to try.
Everyone loves the Big things in Australia so just 1h40m down the road towards Kingston lies Larry The Big Lobster. At 17 metres tall, the larry was an invention by a local fisherman who originally wanted the lobster to be positioned over the top of the complex but due to council regulations it had to sit in front of it.
20. Visit the Petrified Forest at Discovery Bay Park (1h30m south)
