Overview
Mount Gambier Caves, Sinkholes, Volcanoes Adventure
Guided adventure tour
Join us on a geo-nature immersive adventure through South Australia’s incredible Limestone Coast in Boandik Country.
Think caves, sinkholes, craters, limestone cliffs and volcanoes. This Mount Gambier adventure includes opportunities to get up close (and inside!) some of these awe inspiring earth creations with everything taken care of by our guides. We take you snorkeling at spectacular Ewen’s Ponds and kayaking on beautiful Glenelg River, plus you head underground at the world heritage Naracoorte Caves, climb a dormant volcano, explore sinkholes, and float in a salt lake. If that sounds action packed, well it is, but don’t worry we still provide time for a gentle bush walk, time to relax amongst the vines and sample some Coonawarra wines, a beach swim, and some nature therapy.
This is an active and immersive adventure for those wanting to get outside of the comfort zone and experience the wonder through all the senses.
Itinerary
Day 1 | HISTORY ON EARTH (caves and megafauna)
We leave Adelaide in our comfy bus around 7:00am on the South East Freeway. Heading, well South East of course through towns such as Tailem Bend where morning tea awaits.
We continue on to the World Heritage Naracoorte Caves for your Victoria Fossil Cave Megafauna Experience. Recently developed in 2022, this audio visual experience re-creates the movements and scale of some of the megafauna species who inhabited this land. If you would prefer to stay above ground, there is a choice of short walks for you to enjoy. We lunch here at the caves.
Next we call in on a gorgeous winery ‘Brand’s Laira’ for tastings of cab sav and shiraz. Soaking in the beautiful aspect of vines and landscapes of the Coonawarra from the raised deck.
Leaving the cellar door its less than an hour further south to our destination, Mount Gambier. Our base for the next 3 nights. Here, we visit the Umpherston sinkhole, check in to our accommodation at ‘The Commodore’ and get ready for dinner. From our dinner location, we will visit the Cave Gardens in the main street lit up at night.
Meals Included: Lunch, Trail Snacks, 2 Course Dinner
Walking Distance: 1km
Day 2 | FRESH (freshest water and oxygen)
You can join us for an optional sunrise adventure this morning on the highest point in town or have a leisurely start before breakfast. From the high point you will see not just the Valley Lake but also the Blue Lake known for its vivid colour and reflection.
After breakfast we hit the road, firstly to get suited up in our full wetsuits, then on to Port McDonnell. This coastal town is where you are Welcomed to Boandik Country. The Boandik people were the first inhabitants of this area and have much to share with us.
Nearby is spectacular Ewens Ponds. Snorkel and drift through all three sinkholes and witness an underworld of life with the freshest water on earth. You will enjoy Ewens Ponds immediately after it’s annual 3 month park closure. So the water is clean and the plant and aquatic life thriving.
It’s time to warm up once out of the water. We travel to Mt Schank and get up onto the rim of this dormant volcano to take in the views and size of this little cone volcano. Last erupting 5000 years ago this is Australia’s youngest volcano.
We return to Mt Gambier for a BBQ dinner by the lake as the sun sets.
Meals Included: Breakfast, Lunch, Trail Snacks, 2 Course Dinner
Walking Distance: 4km
Day 3 | FLOW (circle of life and nature connection)
After a good night’s rest, we drive over the border to Nelson where the gorgeous Glenelg River flows through to the ocean. This little town is a popular spot for fishing and boating either by motor or by paddle. It is a gateway to the Lower Glenelg National Park. We head deep into the Park and launch the kayaks.
We paddle for a relaxing 8km passing manna gums, stringy barks and blackwood. Bird spotting here may bring sighting of gang gang cockatoos, ravens, wrens, fantails, kookaburras, owls, black duck and shelduck (plus more).
Reaching our destination, we enjoy a fresh lunch on the banks of the Glenelg River. Re-energised, we prepare for our hike along the Great South West Walk trail. The section of trail you walk is shaded, quiet and not commonly used by day walkers. Allowing good opportunities to spot wildlife such as frog, echidna, wallaby, koala and emu. Making this a mindful and nature immersive experience, with gorgeous views of the river below.
After a full day of action, we return to our accommodation and dinner.
Meals Included: Breakfast, Lunch, Trail Snacks, 2 Course Dinner
Walking Distance: 8km
Day 4 | NATURE THERAPY (forest and ocean immersion)
Our morning is a relaxing one if you choose. If you need your sleep or space you can take it easy and stay under the covers.
If you want to insert one last immersive nature experience, head out at sunrise for a therapeutic nature therapy experience near the lakes or get the heart rate up with a trail run.
Your drive home is coastal today and all about recovery and relaxation. Our first stop is Beachport, where we climb down the dunes for a relaxing swim in the ocean. The bay is protected by a reef bringing protective waters for a swim. Then, a short walk takes you to the Pool of Siloam. Known for its incredibly high salt content (7 times higher than the ocean) and it’s healing potential. We float here and enjoy morning tea. There is a shower at the Pool of Siloam for one last wash off before we head to Robe for lunch. This coastal town has many little eateries to choose from, catering to every taste. (If Pool of Siloam is not accessible, an alternative swim/body surf at Long Beach Robe will be offered).
Following the Coorong, with pink lakes and tall sand dunes to admire, we journey home. Rewarded by the opportunity to experience connection to this beautiful part of SA (and Victoria), on your Mount Gambier Adventure.
