Top 10 Things to Do in and Around Mount Gambier, South Australia
Set in the heart of the Limestone Coast, Mount Gambier is South Australia’s second-largest city and one of its most fascinating destinations. Located around 450 kilometres southeast of Adelaide, this vibrant regional centre is built around a dormant volcanic landscape and makes an excellent base for exploring the natural wonders of the surrounding region. From colour-changing crater lakes and lush sunken gardens to crystal-clear sinkholes, caves, and volcanic hikes, Mount Gambier is a destination shaped by geology — and every corner tells a story millions of years in the making.
Blue Lake: Mount Gambier’s Icon
The Blue Lake is Mount Gambier’s most famous attraction and a must-see when visiting the region. This stunning volcanic crater lake is particularly spectacular from December to March, when the water transforms into a vivid cobalt blue.
You can drive to several scenic lookouts around the lake or walk the 3.6-kilometre track that circles its edge, offering ever-changing views across the water and surrounding landscape. In the cooler months, the lake shifts to a softer steel-grey tone, making it worth visiting at any time of year.
Once a limestone cave, Umpherston Sinkhole was formed when the cave roof collapsed. In 1886, local landowner James Umpherston transformed it into a beautifully landscaped sunken garden. Today, visitors can admire the sinkhole from the upper viewing platform or descend the stairs to wander among the lush greenery at the base. Visit in the late afternoon or evening to spot possums emerging among the vines and stone walls — a magical experience.
Tantanoola Caves Conservation Park
Located a short drive from Mount Gambier, Tantanoola Caves may be one of South Australia’s smallest caves, but they are among the most impressive. The single chamber measures around 30 metres wide and 8 metres high, packed with stunning stalactites, stalagmites, and helictites. A 30-minute guided tour takes you through the cave while explaining its geology and history, making it an accessible and fascinating experience for all ages.
Discover Little Blue Lake
Little Blue Lake is a naturally formed, water-filled sinkhole that has become a favourite spot for a refreshing swim. With its striking blue water and easy access via stairs and a floating pontoon, it’s popular with both locals and visitors. The water remains cold year-round, so it’s best for confident swimmers — but even if you don’t take a dip, it’s a beautiful place to stop and admire the clarity of the water..
Explore Ewens Ponds
For an unforgettable underwater experience, Ewens Ponds offers some of the clearest freshwater snorkelling in Australia. These spring-fed limestone ponds are filled with crystal-clear water and vibrant aquatic plants, creating an otherworldly scene beneath the surface. Snorkelling and diving are tightly managed to protect this fragile environment. Bookings are essential through SA National Parks, and fees apply.
Just south of Mount Gambier, Mount Schank is a 100-metre-high dormant volcano with a walking track that leads to the summit and around the rim. The climb is short but steep, and the reward is well worth the effort. From the top, you can peer into the crater and enjoy sweeping views across surrounding farmland toward Port MacDonnell and the Southern Ocean.
Valley Lake & Wildlife Park
Nestled beside the Blue Lake, Valley Lake is another beautiful volcanic crater, offering a more relaxed and family-friendly setting. The area features expansive lawns, picnic tables, BBQ facilities, playgrounds, and walking tracks. There’s also a free wildlife park, where you can spot native birds and animals — we even saw a wallaby and an echidna during our visit.
Visit Lady Nelson Discovery Centre
Located at the Mount Gambier Visitor Information Centre, the Lady Nelson Discovery Centre features a full-size replica of the historic Lady Nelson ship.
Inside the small museum, you’ll find interactive displays and fascinating information about Mount Gambier’s volcanic history, fossils, early exploration, and the role of the Lady Nelson in South Australia’s story.
Take a Guided our of Engelbrecht Cave
Engelbrecht Cave offers a unique underground experience beneath the streets of Mount Gambier. A 45-minute guided tour takes you through the dry sections of the cave, where you’ll learn about its history and see impressive formations. For qualified cave divers, the cave’s crystal-clear waters reveal hidden tunnels and chambers — making it one of Australia’s most renowned freshwater cave-diving sites.
Mount Gambier Heritage Walk
To explore Mount Gambier’s history above ground, take the self-guided Heritage Walk, which features 32 historic buildings and sites dating back to 1863. Pick up a brochure from the visitor centre or access it online, then wander through the city at your own pace, discovering Mount Gambier’s architectural and cultural heritage along the way.
Why Visit Mount Gambier?

Whether you’re hiking volcano rims, snorkelling in sinkholes, exploring caves, or strolling historic streets, the city offers an incredible variety of experiences in a compact and accessible area. It’s a destination that surprises, inspires, and rewards curious travellers — and one that truly showcases the natural beauty of the Limestone Coast.
