A guide to the magical blue lakes of Mount Gambier

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.

Is there anything else I should know? 

Sure, you can either hire a car and make your way to each of the lakes to explore at your own pace, or you can book an Aquifer Tour at Blue Lake, if you prefer a guided experience with a side of history.

    From a scene-stealing country steakhouse to a fine dining eatery, these are the Mount Gambier restaurants worth visiting. 

    Located halfway between Adelaide and Melbourne, this Limestone Coast city has plenty of awe-inspiring geological draws to its name, not to mention world-renowned wine regions right on its doorstep.

    The coast’s once volcanic landscape is blessed with incredibly fertile soils, too, and as a result, it’s home to a bounty of fresh produce. Whether you’re in town for an extended sojourn or you’re just stopping by on a road trip, these are the best restaurants in Mount Gambier.

    1. Elementary by Soul Co

    Those looking for an elevated dining experience should head to Elementary by Soul Co. Helmed by chef Kirby Shearing, the modern Australian menu spans gnocchi with confit duck, mushrooms, and broth, baked egg tart with muntrie compote, burnt sugar and spiced brioche with vanilla parfait, chocolate cream, and hazelnuts. For the full experience, opt for the tasting menu, expertly paired with a range of wines or sakes. If you’re around on a Thursday or Friday, duck in for the express lunch where you’ll get an entree, main course and a side all for just $45.

    The intimate space seats just 23 guests and is swathed in moody charcoal tones and dark timber furniture for a cosy dining experience.

    Address: 12 Margaret St, Mount Gambier

    2. The Barn Steakhouse

    This local heavyweight is the reigning champion when it comes to perfectly cooked steak. And its owners, the Cleves family, go one step further than most steakhouses, breeding their very own Hereford cattle on properties in the region, and ageing all the cuts in-house for a minimum of eight days too.

    Beyond its steak credentials, The Barn also takes a holistic view of the veggies and herbs that accompany its dishes, which are house-grown, preservative- and pesticide-free in the rich volcanic soils that surround the restaurant, and plucked fresh daily.

    Why not kick off the evening’s proceedings with a glass of something sparkling from The Barn’s award-winning 750-wine-label-strong cellar, with the vast majority of the restaurant’s drops sourced from the surrounding Limestone Coast wineries.

    Then tuck into some house-made pâté, served with hot toast and quince glaze, and perhaps some seared scallops with prosciutto before moving onto the main event – a rump, porterhouse, or eye fillet, served alongside a continental salad and a sour cream and spring onion topped baked potato.

    The Barn Steakhouse is located amid lush farmland, just a 10-minute drive south of the city.

    Address: 747 Glenelg River Rd, Mount Gambier

    3. Thyme at The Lakes

    Savour the flavourful meals at Thyme at the Lakes.

    Perched right on top of the city, Thyme at The Lakes boasts an incredible view of Mount Gambier, with food presented as spectacularly as the city below you. With attentive service to top it all off, Thyme at The Lakes showcases the best of local produce in an exciting and elegant dining experience, with the modern menu taking inspiration from both Australian and international cuisine.

    From the mouth-watering Spanish-inspired grilled paella to the melt-in-your-mouth lamb rack, Thyme also boasts a vegetarian and vegan menu for those who aren’t meat lovers. Hot tip: Do not skip their dessert menu. The restaurant boasts MasterChef-worthy dishes like the Strawberry & White Chocolate Sphere, or the Hazelnut Affogato makes the perfect palate cleanser.

    Address: 17 Lake Terrace W, Mount Gambier

    4. Wild Ginger Thai

    Authentic classic Pad Thai with shrimps. Thai shrimp satay with sweet chili sauce. Tom Yum soup with coconut milk (Tom Khaa). Spicy shrimp salad. Flat lay top-down composition on concrete background.

    Wild Ginger Thai’s dishes pack a punch of flavour.

    When Wild Ginger first opened its doors, it was the new kid on the block. Since then, head chef and owner Bee Ketphong and her team have established a reputation for fine Thai cuisine that has made Wild Ginger one of Mount Gambier’s most popular eating destinations for both lunch and dinner.

    From the flavour-packed fish cakes to the range of stir-fries, curries and noodle dishes infused with all those powerful Thai flavours of chilli, lemongrass, basil or satay, Wild Ginger is all about Thai cooking.

    Bee is focused on using fresh, local produce to create fine Thai dishes, ranging from mild dishes to those that are packed with spicy flavours. And all of Wild Ginger’s menu items are available for takeaway as well.

    Address: 17 Commercial St West, Mount Gambier

    5. Natural Born Grillers

This burger is loaded with a vegetarian burger meat substitute, fresh salad, melted halloumi cheese and spanish onion and tomato. The burger is sandwiched between glazed buns.

    Natural Born Grillers has an entirely meat-free menu for the vegos and vegans among us.

    When only a burger will do, make a beeline for Mount Gambier’s Natural Born Grillers. Whether you’re after fried chicken, pulled pork, beef patties, or even something veggie-friendly (there’s a dedicated meat-free menu), NBG delivers.

    There’s a multitude of indulgent, deep-fried sides on offer too: potato gems, loaded fries, onion rings, popcorn chicken, and mozzarella sticks. While this burger joint has Mount Gambier’s fast-food market cornered, Natural Born Grillers’ rather spartan interior means it’s not exactly the place to go if you’re after an evening of ambience.

    Address: Shop C, 3 Compton Street, Mount Gambier

    6. Bahn Kubo

    The decor at this pan-Asian eatery is nothing to write home about (hello bright white lights, plastic-backed chairs, loud lime and orange colour scheme, and wipe-clean plastic tables). But thanks to its friendly and fast service, super reasonable prices and moreish dishes, Bahn Kubo does something of a roaring trade. The barbecue pork (char siu) and Thai roast duck receive rave reviews.

    Address: 139 Commercial St W, Mount Gambier

    7. Southern Thai Cafe

    Adding to Mount Gambier’s amazing Thai offering, Southern Thai Cafe brings a fresh look to the cuisine with a focus on the authentic tastes of Southern Thai food and an emphasis on value and service.

    Southern Thai Cafe is the dream of Wilawan Churueangsuk (Jieb), who came to Mount Gambier from Southern Thailand 17 years ago. Now an Australian Citizen living here with her husband, David and their children, Jaime and Emily, Jieb’s Southern Thai Cafe is also about family.

    Address: 53 Gray Street, Mount Gambier
