Walking & Hiking
Crater rims, cave reserves & coastal tracks
The best walking & hiking in Limestone Coast
Walk the rim of an extinct volcano, follow boardwalks through fossil-rich wetlands or trace wild coastline through conservation parks. The Limestone Coast's volcanic and karst landscapes make for unforgettable walking.
The Limestone Coast packs an extraordinary variety of walks into one corner of South Australia, from volcanic crater rims to coastal heathland and ancient cave country. In Mount Gambier, the sealed 3.6km circuit around the Blue Lake and the climb to Centenary Tower on Valley Lake reward walkers with sweeping volcanic views.
Further afield, Naracoorte Caves National Park threads surface trails between World Heritage fossil caves, while Little Dip Conservation Park near Robe winds through dunes, lakes and clifftops. Birdwatchers head for the boardwalks of Bool Lagoon, one of the state's most important wetlands.
Many trails are short, flat and family-friendly, making them easy to combine with cellar doors or beach time in a single day. Cooler months bring the most comfortable walking, though shaded crater and cave tracks stay pleasant through the warmer season too.

Walking & Hiking in Limestone Coast - frequently asked questions
What are the best walks on the Limestone Coast?
The signature walk is the sealed 3.6km circuit around Mount Gambier's Blue Lake, often combined with the steep climb to Centenary Tower for views across the volcanic crater. Other standouts include the Cape Buffon Walk along the limestone cliffs and sea stacks of Canunda National Park, the boardwalks through fossil country at Naracoorte Caves, and the terraced descent into the Umpherston Sinkhole.
Is Naracoorte Caves National Park worth visiting for walkers?
Yes - Naracoorte is South Australia's only World Heritage site, listed in 1994 as part of the Australian Fossil Mammal Sites for its half-million-year fossil record. Above ground you can follow several self-guided trails, including the roughly 2.2km World Heritage Hike linking the Wonambi Fossil Centre to Victoria Fossil Cave. Park entry is free, though the underground guided cave tours are ticketed and worth booking ahead.
When is the best time to walk the Blue Lake?
You can walk the Blue Lake circuit year-round, but the lake is at its most striking from around November to March, when it shifts from winter steel-grey to a vivid cobalt blue. The colour is usually most vibrant in January and February. Spring and autumn bring milder temperatures for the exposed climb up to Centenary Tower, which can be hot in midsummer.
Are the Limestone Coast walking trails dog friendly?
Most of the headline walks sit within national and conservation parks - including Canunda, Naracoorte Caves and Piccaninnie Ponds - where only accredited assistance dogs are permitted. If you are travelling with a dog, stick to town reserves and dog-friendly beaches rather than the park trails. Always check the current rules for each park before you set out.
Can you still swim or snorkel at Piccaninnie Ponds while walking there?
The conservation park and its coastal walking trail and wetland boardwalks remain open, but immersive water activities like diving and snorkelling have been suspended to allow the aquatic vegetation to recover, with permits not currently being issued. You can still follow the trail through coastal heath and tea-tree to the lookout over the spring-fed ponds. Check the parks website for the latest status before relying on a swim or snorkel.
