We love exploring our own backyard here in South Australia, and a recent road trip took us back to Mount Gambier in the state’s South East. This town holds a special place in Lindsay’s heart — he was born and raised here — so we’ve spent plenty of time wandering its lakes, caves and quirky local spots.
With all our visits over the years, we feel confident sharing the best things to see and do when you’re in Mount Gambier.

Where Is Mount Gambier?
Mount Gambier sits in the south‑east corner of South Australia, right near the Victorian border. It’s perfectly placed for a road trip — roughly 4.5 hours from Adelaide and 5 hours from Melbourne — making it an easy stop between the two cities or a great weekend getaway on its own.
The town is part of the Limestone Coast, a region known for its volcanic craters, sinkholes, lakes and underground cave systems. That dramatic landscape is exactly what makes Mount Gambier so unique. One minute you’re driving through farmland, and the next you’re standing on the edge of a crater lake or peering into a sunken garden.
Best Things To Do In Mount Gambier
Now that we know exactly where Mount Gambier sits on the Limestone Coast, let’s jump into all the amazing things you can see and do while you’re there.
1. Lady Nelson Visitor Information Centre — Your Best Starting Point
The Lady Nelson Visitor Information Centre is far more than a place to grab brochures. Inside you’ll find interactive displays, a small discovery centre and incredibly friendly staff who know the region inside out.
It’s the perfect spot to get up‑to‑date information on walking tracks, cave openings and local events. If you’re travelling with kids (or the young at heart!), they’ll love the replica ship and the discovery area, which shares stories of the region’s First Nations people. At the bottom of the trail, you can also watch a short but fascinating video following a cave diver exploring Engelbrecht Cave — a great intro to Mount Gambier’s underground world.
There are also exhibits on the area’s geology, plus a full‑scale replica of the Lady Nelson right out the front, which makes for a fun photo stop. Parking is plentiful, the toilets are spotless, and if you’re after a souvenir or a cold drink, the centre sells the region’s famous Blue Lake Lemonade (once made by the local Molony’s brand). It’s known for its bright blue colour — and its ability to turn your number twos bright green!
Address – 35 Jubilee Highway East, Mount Gambier
2. Blue Lake – The Iconic Colour-Changing Crater Lake
If you’ve seen photos of Mount Gambier, chances are they were of the Blue Lake — the town’s most famous attraction, and for good reason. It’s stunning in every season. From November to March, the water transforms into an unreal electric blue thanks to a natural reaction between sunlight and the lake’s limestone base.
The 3.6 km rim walk along John Watson Drive is easy and scenic, with plenty of lookouts offering different views into the crater. The vivid turquoise colour appears when the sun warms the top layer of water, causing calcium carbonate particles to form and scatter light in a way that makes the lake glow.
These photos are from a trip we took in June, so we missed the bright summer blue — but even in winter, the lake is still beautiful. It’s also fascinating to remember that the Blue Lake is actually a dormant volcanic crater, formed roughly 4,300 years ago during explosive eruptions.
Fun fact: the Blue Lake is Mount Gambier’s primary drinking water source, which means swimming isn’t allowed — but the views more than make up for it!
Address – John Watson Drive, Mount Gambier
3. Umpherston Sinkhole — The Sunken Garden
As much as we love exploring the lakes around Mount Gambier, Umpherston Sinkhole is still one of our absolute favourites. Once a collapsed limestone cave, it’s now a beautifully landscaped sunken garden filled with hanging vines, terraced walls and a calm, almost hidden‑away atmosphere — complete with its own resident possums.
Visit in the late afternoon if you can. The light filters through the vines beautifully, and that’s also when the possums start to appear. They’re pretty used to people, so you’ll often spot them climbing along the garden walls or peeking out from the greenery. If you come back after dark, you can even hand‑feed them — they’re big fans of apple and banana.
Access to the garden is via a series of concrete steps, so it’s unfortunately not wheelchair or pram friendly, but you can still admire the sinkhole from the viewing platforms above.
Address – Jubilee Highway East, Mount Gambier
4. RSL War Museum — Small but Powerful
The RSL War Museum is one of those true hidden gems that often gets overlooked by visitors, but it absolutely deserves a spot on your Mount Gambier itinerary. It’s run by passionate volunteers who have gathered an impressive collection of uniforms, medals, letters, photographs and personal stories from local servicemen and women.
The displays cover a wide range of conflicts — the Boer War, WWI, WWII, the Korean War, the Vietnam War, Afghanistan and Iraq — giving you a real sense of how deeply this community has been shaped by service.
The museum is made up of five separate rooms located inside the RSL building. If the doors happen to be closed when you arrive, just ask at the bar or reception — the staff are always happy to open it for you. It’s a small space, but incredibly meaningful, and you really do feel the personal connection behind every item on display.
If you’re a history buff, you could easily spend a couple of hours here. Lest We Forget.
Address – 16 Sturt Street, Mount Gambier
5. Mount Schank — A Volcanic Crater You Can Hike
Mount Schank, known as Australia’s youngest volcano is a short drive from town and gives you the chance to climb an actual volcanic cone. The 900m track to the top is steep in sections, but once you reach the rim, the views are incredible — rolling farmland, ancient lava flows and the perfectly shaped crater below.
You can walk the full circuit around the top, which takes about an hour depending on how often you stop for photos. Wear sturdy shoes because the volcanic gravel can be a bit slippery, but otherwise it’s a straightforward and rewarding hike.
There are toilet facilities and a small picnic area located at the carpark near the entrance and dogs are welcome.
Address – 92 Mountain Path Road, Mount Shank
6. Cave Gardens – A Quiet Green Pocket in the City Centre
Cave Gardens is one of those spots that’s incredibly easy to visit but often overlooked, even though it sits right in the heart of Mount Gambier. What looks like a simple park from above actually hides a deep sinkhole garden below, with viewing platforms that let you peer down into the limestone cavity and see the layers of rock that shaped the region.
In spring and early summer, the gardens come alive with colourful flowers and lush greenery, but even if you visit outside these seasons, it’s still beautiful. There’s also a small waterfall feature that flows after heavy rain, adding a bit of drama to the sinkhole walls.
It’s an easy, accessible stop — perfect if you’re already exploring the city centre — and a nice way to appreciate Mount Gambier’s volcanic landscape without needing to venture far. Even a short visit gives you a sense of how unique the geology is here.
There is plenty of surrounding parking available and toliet facilities in the Riddoch Curtural Centre which sits behind the Cave Gardens. You will also find picnic tables available and dogs are welcome.
Address – 1 Bay Road, Mount Gambier
7. Old Railway Yards — Industrial History Meets Street Art
The old railway yards are a fun mix of history and creativity. What used to be a busy transport hub has been transformed into a public space with a 5.4km walking path, a longer bike path, murals, sculptures and remnants of the original rail infrastructure.
It’s a great spot for a casual wander or some photography — the old turntable, rusted tracks and colourful street art make for interesting contrasts. If you enjoy exploring places with a bit of character, you’ll love it here.
There are modern BBQ stations, sheltered picnic areas and accesible toilets located in the original train signal box.
Address – Railway Terrace, Mount Gambier
8. Riddoch Arts & Cultural Centre — Art, History & Local Stories
The Riddoch Arts & Cultural Centre looks like a typical regional gallery, but inside you’ll find a mix of contemporary art, local history, a gift shop and interactive displays that really help you understand Mount Gambier’s volcanic landscape.
One of the highlights is the Volcano Film Experience, which walks you through how the region’s craters, lakes and sinkholes were formed. It’s engaging and makes exploring the rest of the town even more interesting once you know the geology behind it all. The film screens at 11am and 2pm daily.
The rotating exhibitions are always worth a look too — you’ll often find works by South Australian artists, First Nations creators and local storytellers. It’s a great way to slow down for an hour, especially if the weather turns!
Address – 1 Bay Road, Mount Gambier
9. Cast in Blue — Snap a Selfie with Mount Gambier’s ‘Blue Blob’
Just outside the Riddoch Cultural Centre, you’ll find one of Mount Gambier’s quirkiest public artworks: Cast in Blue. Locals affectionately call it the Blue Blob, and it’s become a fun little photo stop for anyone wandering through the city centre.
The sculpture represents a mystical megafauna creature said to have emerged from the deep aquifers beneath the region — a playful nod to Mount Gambier’s volcanic and limestone foundations. Its smooth, bright‑blue form stands out against the historic buildings around it, making it impossible to miss.
It’s the perfect quick stop while exploring the Riddoch or the surrounding street art.
10. Limestone Coast Pantry — A Quirky Spot for Coffee, Cake or a Bite to Eat
Limestone Coast Pantry is set inside the historic former Central State Worsted Mill, which opened in 1925, the space blends heritage character with a fun mix of local businesses and retro charm. It’s the kind of spot where you walk in for a coffee and end up wandering around just to take in all the quirky details.
Inside, you’ll find displays of old machinery, funky wall art and a cosy, slightly vintage vibe that makes it perfect for a relaxed break during your day of sightseeing. The Pantry stocks a great range of Australian and regional produce, including preserves, gifts, heat‑and‑serve meals and pantry staples — ideal if you’re road‑tripping or looking for something local to take home.
Of course, the main drawcard is the food. They serve meals, cakes, coffee and tea. It’s a lovely spot to slow down, recharge and enjoy a taste of the Limestone Coast.
Address – 1/20 Harrald Street, Mount Gambier
11. Centenary Tower Lookout — Sweeping Views Over the Crater Lakes
If you’re up for a short but VERY steep climb, Centenary Tower rewards you with some of the best views in the region. The track winds up from the Valley Lake area, and although it’s a bit of a leg‑burner, the panoramic views over the crater lakes and volcanic landscape are absolutely worth it.
On days when the tower is open, you can head inside for a small entry fee and learn more about the area’s history. Even if it’s closed, the lookout platform still gives you incredible photo opportunities. It’s especially beautiful on a clear day when you can see right across the city and out to the distant farmland.
Address – Elliott Drive, Mount Gambier
12. Valley Lake Conservation Park — Picnic Spots, Walks & Wildlife
Valley Lake sits quietly beneath the Blue Lake crater, and it’s one of the easiest places to unwind in Mount Gambier. The area is beautifully maintained with grassy picnic spots, BBQ facilities, playgrounds, toilet facilities and plenty of shady trees. You will often find the locals enjoying water sports here in the warmer months.
If you enjoy walking, there are several short trails around the lake and through the surrounding conservation area. Keep an eye out for birdlife, wallabies and the occasional koala snoozing in the gums. It’s also a lovely spot for sunrise or sunset when the light hits the crater walls.
Unfortunately on our most recent visit the park was closed due to roadworks so the below photos are from one of our previous trips.
Address – Davidson Drive, Mount Gambier
13. Engelbrecht Cave — A Cave System Beneath the City
Engelbrecht Cave is one of Mount Gambier’s most unique attractions because it sits right in the middle of town. From the street, you’d never guess there’s a network of limestone caves and underwater passages beneath your feet.
Guided tours take you down into the sinkhole where you’ll learn about the geology, the cave’s formation and the brave cave divers who explore the submerged tunnels. The cave’s honeycomb appearance and the missing stalactites makes it unique.
It’s wild to think that Engelbrecht Cave was once Mount Gambier’s first rubbish tip, especially when you see how pristine it is today. What makes it even more fascinating is that this sinkhole connects to a vast underground water system hidden beneath the city. The water is so crystal clear that it looks barely a foot deep — but in reality, it drops to around seven metres. It’s one of those places that really makes you appreciate just how much of Mount Gambier’s landscape exists below the surface!
Address – 26 Chute Street, Mount Gambier
14. Explore the Main Street — Cafés, Boutiques & Local Charm
Mount Gambier’s main street is compact, easy to explore and full of little surprises — from cosy cafés to quirky boutiques and colourful street art tucked between buildings. If you enjoy browsing local shops or just soaking up the feel of a regional town, this is a lovely way to spend an hour or two.
Start along Commercial Street, where you’ll find a mix of heritage buildings, independent stores and plenty of spots to grab a coffee or a bite to eat. There are homewares shops, vintage finds, clothing boutiques and small businesses selling locally made products — ideal if you’re looking for a unique souvenir or something handmade from the Limestone Coast.
The laneways around the CBD also hide some great murals, so it’s worth taking a few detours off the main strip.
Whether you’re shopping, people‑watching or simply stretching your legs between attractions, exploring the main street gives you a nice feel for everyday life in Mount Gambier — relaxed, friendly and full of character.
Address – Commercial Street, Mount Gambier
15. Little Blue Lake — A Natural Swimming Hole in an Old Volcanic Sinkhole
Little Blue Lake is one of the Limestone Coast’s most popular summer swimming spots — a deep, circular sinkhole filled with incredibly clear, cool water. Unlike the Blue Lake in town, this one is open for swimming, and on warm days you’ll find locals and travellers floating, diving and cooling off in its bright blue water.
The lake sits inside an old volcanic sinkhole, giving it steep limestone walls and a dramatic, almost hidden‑away feel. A set of metal stairs leads you safely down to the water, and there’s a floating pontoon that makes getting in and out much easier. The water stays refres
Even if you’re not planning to swim, it’s still worth a visit. The colour of the water is beautiful, and the surrounding farmland gives it that classic Limestone Coast charm. It’s only a short drive from Mount Gambier, making it an easy addition to your itinerary.
Good to know: the lake is VERY deep so it’s best suited to confident swimmers and there is no shade so be sure to bring a hat and sunscreen.
Address – Mount Salt Road, Mount Schank
16. Rook Wall Lookout – Views from Three Levels
Located just across the road from the Blue Lake, this small lookout offers three different viewing levels and a handy little parking area. From here, you can also walk through the tunnel under the underpass to reach another lookout, and a few short walking trails branch off from this spot as well.
Parking is limited, but the lookout itself is worth a stop.
Address – Bay Road (Riddoch Highway), Mt Gambier
