With its vibrant hue, Blue Lake Mount Gambier is celebrated for all the right reasons, but the good news? There’s plenty more where that came from. 

To visit Blue Lake Mount Gambier or Little Blue Lake Mount Gambier? It’s far from the only question you’ll be asking when you descend on this breathtaking patch of South Australia’s Limestone Coast, such as…

What exactly are the Blue Lakes of Mount Gambier?

It’s unusual that so many spectacular lakes should be concentrated so close to one another, but they’re the result of explosive volcanic activity rocking the earth some 5,000 years ago, creating a series of crater lakes.

While Blue Lake/Warwar, celebrated for the mysterious way it turns a vibrant cobalt (and occasionally, turquoise) from November onwards before making the transition to steel grey come March, has become synonymous with Mount Gambier, it’s actually just one of several lakes that make up the Crater Lakes Precinct which includes Valley Lake/Ketla Malpi, Brownes Lake/Kroweratwari and Leg of Mutton Lake/Yatton Loo.

But wait, you forgot Little Blue Lake?

Disregard the ‘lake’ in its title, Little Blue Lake – again, a dazzling body of water (some 47 metres deep) which turns a brilliant blue between November and March, is actually a sinkhole just 15 minutes from Mount Gambier.

Popular with swimmers and cave divers (the latter only permitted for divers who hold at least the CDAA Deep Cavern grade dive rating, Little Blue Lake with its stairs and floating pontoon is one of Australia’s most accessible sinkholes.

What’s the best way to experience Blue Lake? 

Let’s start with how you won’t be experiencing it; as the lake serves as the city’s water supply, there is no swimming allowed. The good news? You can still enjoy this almost circular, one kilometre lake however by tackling the 3.6-kilometre walking trail that follows its rim, a 45-minute journey best started at the Pioneer Memorial (although you can start the walk from any point).

Scenic lookouts are dotted around the lake, but keep an eye out for Rotary Lookout where you can view the Centenary Tower, the Pumping Station and Mount Schank. As mentioned, if you can time your visit to slot in neatly between November and March, you’ll see the lake at its vibrant best.

Which other lakes do you recommend around Mount Gambier? 

Take a short drive to the Crater Lakes where Valley Lake is home to a wildlife-filled conservation park heaving with native flora and fauna. While some choose to make the most of water sport options on the water, this is the ultimate spot for a relaxed picnic, a casual barbeque (there are free barbeque facilities onsite), or if you’re feeling active, a round or two of disc golf at the Crater Lakes Disc Course.

Our recommendation? Set up a spot by Brownes Lake/Kroweratwari, the site of the original Mount Gambier Botanical Gardens and bring the kids: the adventure playground will thrill kids and kidults of all ages.

Valley Lakes Recreation Area is particularly picturesque in the autumn months when the flame trees put on a spectacular show of vibrant yellow, red and burnt orange hues.

Be sure to also check out the curiously named Leg of Mutton Lake – for its shape which is, you guessed it, shaped like a lamb leg. Although it’s now dry due to reductions in the water table, the dramatic wooded area is an excellent location for hikes.

Choose between the 4.2-kilometre Mountain Trail (begin at Mark’s Lookout and follow the track in an anti-clockwise direction for the best views), the moderate 1.7-kilometre Pepperpot Trail and Blue Lake Circuit, or for those who prefer something shorter, the Oaks, Blue Gum and the The Browns Lake walks.

Farm fresh produce to a trail of lights: the ultimate guide to Mildura

    Rachel Lay Rachel Lay
    Continue
    The charm of Mildura is hidden in plain sight along the Sturt Highway. The capital of Tropical North Victoria is in a league of its own.

    From the moment you arrive in Mildura, the warm air and palm trees invite you to slow down. While most Australians might drive right past it, Mildura is full of surprises. Here you’ll spend one day witnessing over 50,000 years of First Nations history in a UNESCO-listed National Park, and the next dining in a hatted restaurant after wandering through 12,500 fireflies as the outback sunset bursts to life above. From roadside fruit stalls and family-run wineries to houseboats and galleries, it’s time to explore Mildura.

    Feast Street, at the heart of Langtree Avenue in Mildura.
    Taste, wander and be surprised in Mildura.

    Taste Mildura’s produce

    It makes sense to start your trip by addressing the most important question: where to eat. In the beating heart of Australia’s food bowl, sample the local produce directly from the source. And then, of course, experience it through the menu of a hatted chef. Or sandwiched between pillowy slices of Nonna’s ciabatta.

    Rows of orchards and olive groves invite you to spend the day traipsing from farm to farm. Taste olives propagated from Calabrian trees brought over in the 40s, oranges picked right from the tree and squeezed into juice and spoons full of honey. Bring the holiday back to your kitchen by stocking your pantry at roadside produce stalls, or calling into the ‘silver shed’ (Sunraysia’s gourmand Mecca).

    Thanks to the warm, balmy air and fertile soils, the wineries dotted along these hills produce award-winning local wines. Like Chalmers, a family-run, innovative winery dedicated to making their wines as sustainable as possible. And picturesque Trentham Estate offers views of the snaking Murray River as you sample their vintages.

    Venture beyond the gnarled shadows of olive groves and fragrant rows of blossoming fruit trees and you’ll find an otherworldly side to Mildura. With Discover Mildura as your guide, visit Murray River Salt’s Mars-like stacks. The naturally pink salt is formed from an ancient inland sea and evaporated entirely by the sun to create one of the region’s most iconic exports.

    Start your day with just-squeezed sunshine.

    Hatted dining & Italian history

    Mildura is home to a proud community of Calabrians and Sicilians. This, paired with the exceptional local produce, means that you can find paninos on par with those in Italy. The Italian is a Paninoteca serving up made-to-order, hefty, authentic Sicilian paninos. Nonna Rosa’s pork meatballs, slowly cooked in tomato ragu and served in a crusty, fluffy roll topped with gratings of Grana Padano cheese and salsa verde, will call you back to Mildura for the rest of your days.

    To find hatted dining in Mildura, simply follow the staircase down into the basement of the historic Mildura Grand Hotel to find Stefano’s. Following the muscle memory and instinct of his Italian roots, he delivers on the principle of ‘cucina povera’. That is, the Italian cooking ideology that turns simple, local ingredients into magic.

    Things to do in Mildura include dining at the acclaimed Stefano’s, where simple local ingredients are transformed into Italian culinary magic beneath the historic Grand Hotel.
    Bite into Mildura’s Italian heritage.

    Discover a thriving culture scene

    The city is alive with culture. Whether it’s painted on the town’s walls, told in ancient yarns, or waiting for you in a gallery.

    The Mildura Arts Centre was Australia’s first regional art gallery. Behind the walls of Rio Vista Historic House, you’ll find a lineup of ever-changing exhibitions. The gallery’s wall space pays tribute to the art and songlines of local First Nations People, the region’s awe-inspiring landscapes and more. Outside, on the gallery’s lawn, find 12 contemporary sculptures in the Sculpture Park.

    Mildura’s streetscapes are a punch of colour. Swirling strokes of paint blend the winding artery of the Murray River, red dirt and local characters into a story you can see with your own eyes, thanks to the Mildura City Heart’s Mural Art Project. Pick up a copy of the Murals of Mildura guide from the Visitor Information Centre.

    Follow the border of NSW and Victoria on a map and you’ll see it hugs the curves of a tiny island on the Murray. That’s Lock Island, where, as the sun and moon trade places, the island comes alive as darkness falls. The island is dotted with 12,500 firefly lights that lead you on a meandering path through the outback sunset. The installation is known as Trail of Lights and was created by the same visionary who dreamt up Field of Light at Uluṟu, Bruce Munro.

    Things to do in Mildura include exploring its rich cultural scene. From vibrant street art and ancient stories to exhibitions at the Mildura Arts Centre, Australia’s first regional gallery.
    Find culture around every corner.

    Wonder at ancient landscapes

    The landscapes of Mildura feel almost transcendental. The skyline bursts to life with reds, pinks, and deep, sparkly night skies.

    The nature will leave you in awe. See hues of pink water changing with the weather at Pink Lakes inside Victoria’s largest national park, Murray Sunset National Oark. Cast a line into Ouyen Lake. Watch the sunset against 70-metre tall red cliffs that reflect the setting sun. Or get the heart racing and sandboard down the Perry Sandhills dunes, formed 40,000 years ago at the end of an ice age.

    Just don’t leave without following the twists and turns of the Murray. Stroll or ride along the Shared River Front Path, or jump onboard a boat for a scenic ride.

    Your itinerary will be incomplete without a visit to UNESCO World Heritage-listed Mungo National Park. Head out with an Indigenous ranger to witness ancient campsites and footprints, before standing in awe of ancient civilisation near the discovery site of Mungo Man—Australia’s oldest human skeleton at 42,000 years old.

    Mungo National Park at night is a vast, silent landscape where ancient dunes glow under moonlight and stars blanket the sky in breathtaking clarity.
    Walk in the footsteps of ancient civilisation.

    Meet your home away from home

    On equal par with planning your meals and adventures, is finding the perfect place to relax at the end of each day.

    Sleep inside a Palm Springs postcard at Kar-Rama. A sleek boutique hotel complete with a butterfly shaped, sun-soaked pool. Here you’re staying right in the heart of Mildura but you’ll feel worlds away. Or if you really wish to connect with nature, a night glamping under the stars at Outback Almonds will have you spellbound.

    When in Mildura it’s only right to stay on one of the Murray River’s iconic houseboats. Wake up each day to the calm waters of the Murray lapping outside your window. Enjoy days full of river swims, fishing and exploring. All boats are solar-powered and can be self-skippered or moored along the river.
