Overview
Little Blue Lake is a small but visually arresting maar crater lake located near the township of Mount Schank, roughly 20 kilometres south of Mount Gambier in South Australia's lower South East region. Like its more famous neighbour Blue Lake in Mount Gambier, it owes its vivid blue-green colouration to the optical properties of very clear, calcium-carbonate-rich water interacting with sunlight — though the exact seasonal colour behaviour here is less dramatic than at Blue Lake.
The lake sits within a broad, shallow volcanic crater and is bordered by low pastoral land. It is a quiet, unhurried stop rather than a major tourism hub, attracting travellers who are exploring the Limestone Coast or the volcanic features of the region. Facilities on-site are minimal, which keeps the atmosphere genuinely tranquil.
Little Blue Lake is administered within a local reserve and is accessible to the public, though visitors should verify current access conditions locally or with the Limestone Coast regional tourism body, as conditions can change seasonally.
Before You Go
Visas
Australia requires a valid visa or electronic travel authority for almost all international visitors. For specific requirements relevant to your passport, check the TravelerPulse Visas section and the official Australian Department of Home Affairs website.
What to Pack
- Sun protection is essential year-round in South Australia: sunscreen, hat, and sunglasses
- Sturdy walking shoes or trail shoes if you plan to walk around the crater rim
- Water and snacks — there are no food or drink vendors at the lake itself
- A camera or phone with a wide-angle lens to capture the full crater and water colour
- Insect repellent, particularly in warmer months
Connectivity and Services
Mobile coverage in rural South Australia can be patchy outside towns. Carry a downloaded offline map. Fuel up and stock up on supplies in Mount Gambier before heading out to this area.
Getting There
By Air
The nearest commercial airport is Mount Gambier Airport (MGB), which has regular flights connecting to Adelaide and Melbourne. From there, Little Blue Lake is approximately 20–25 kilometres by road. Verify current flight operators and schedules on the official airport or booking sites, as regional services change.
By Car
Driving is by far the most practical way to reach Little Blue Lake. From Mount Gambier, head south toward Port MacDonnell and watch for signage to Little Blue Lake near the Mount Schank area. The roads are generally sealed; verify the final access road condition locally, especially after heavy rain. From Adelaide, the drive is roughly 450 kilometres via the Dukes Highway — approximately 4.5 to 5 hours.
By Bus
Long-distance coach services run between Adelaide and Mount Gambier (verify current operators and schedules locally). However, there is no regular public transport to Little Blue Lake itself. A hire car from Mount Gambier is the practical option for independent travellers.
Getting Around
Little Blue Lake and its immediate surroundings are best navigated on foot once you have arrived by car. The crater rim walk is short and relatively flat, giving views over the water and surrounding pastoral land.
For the wider lower South East region — including Mount Schank, Port MacDonnell, and the Coonawarra wine region — a hire car is essential. Hire car companies operate out of Mount Gambier; verify availability and book ahead during peak holiday periods.
Things to See & Do
Crater Rim Walk
A straightforward walk around the rim of the maar crater is the primary activity at Little Blue Lake. The walk provides elevated views of the lake's blue-green water below and the surrounding flat volcanic landscape. The path is informal in sections; wear appropriate footwear.
Photography
The lake's colour and the circular geometry of the crater make it a compelling subject, especially in morning or late-afternoon light when shadows are long and the water colour is most vivid.
Swimming
Swimming in the lake has historically been permitted and is popular in warmer months, but visitors should verify current rules and safety conditions locally before entering the water. There are no lifeguards on duty.
Combined Itinerary Suggestions
- Pair a visit here with the nearby Mount Schank volcanic crater, which offers a walk into its interior
- Continue to Port MacDonnell for a coastal contrast — rock lobster fishing community on the Southern Ocean
- Incorporate a drive through the Coonawarra wine region (north of Mount Gambier) for cellar-door visits
Food & Drink
There are no cafes, kiosks, or restaurants at Little Blue Lake. Bring your own water and food for any picnicking. The nearest reliable food and drink options are in Mount Gambier, which has a full range of cafes, restaurants, bakeries, and supermarkets. Mount Gambier is the regional hub and offers cuisines ranging from casual pub meals to more considered dining. Verify specific venues locally, as small-town hospitality businesses can change hours and ownership.
Practical Information
Emergency Services
Australia's national emergency number is 000 (police, fire, ambulance). Mobile signal can be unreliable in rural areas around Little Blue Lake; plan accordingly.
Toilets and Facilities
Basic facilities may be available at the lake reserve; verify locally before relying on them. Mount Gambier has full public facilities.
Entry Fees
At the time of writing, access to Little Blue Lake reserve has generally been free of charge, but verify current status with the Limestone Coast tourism authority or local council, as this can change.
Accessibility
The terrain around the crater rim is uneven in places. Visitors with mobility limitations should assess conditions locally before committing to the rim walk.
Weather Awareness
The lower South East of South Australia experiences hot, dry summers (temperatures can exceed 35 °C on extreme days) and cool, wet winters. Spring and autumn offer the most comfortable walking conditions. Afternoon thunderstorms are possible in summer.
Safety
Little Blue Lake is a generally safe and low-risk destination. The main hazards are environmental: steep and informal crater rim edges, potential slippery conditions after rain, and sun exposure in summer.
Keep children supervised near the crater rim and lake edge. If swimming, be aware there are no safety patrols and water depth varies. Snake awareness is sensible in rural South Australian grasslands, particularly in warmer months — watch where you step and do not attempt to handle snakes if encountered.
As mobile coverage can be limited, inform someone of your plans if visiting in a small group or alone.
