Blue Lake Mount Gambier (Ockert Le Roux)

Geological wonders.

From Caves and Craters, to Sinkholes and Mountains, the limestone coast is home to some of Australia's most unique and iconic geological and natural wonders.

Umpherston Sinkhole.

Tucked conveniently in the heart of Mount Gambier the spectacular Umpherston Sinkhole has been dropping jaws for generations. Formed by millions of years’ limestone corrosion, this masterpiece of Mother Nature is a perfect spot to hang out when the heat’s on, with cool green glades offering a sweet little sanctuary in summer.

Like all our natural attractions, every season is different, so it's also worth heading back to see Spring and Autumn's stunning flower display.

You’ll find it’s also inhabited by some pretty loveable locals, with possums emerging daily at dusk.

The Blue Lake.

The mysterious and very aptly named Blue Lake is a genuine icon in every sense of the word, and no visit to ‘The Mount’ is complete without taking a little time to gaze into this cauldron of coolness.

From November to March, the steel greys of cooler months mysteriously transform to bright cobalt blues that are so vivid it’s had the science world talking for generations. Nestled in one of three extinct volcanic craters, it’s a great spot to stretch your legs around the 3.6km road and walking track.

Naracoorte Caves.

The World Heritage-Listed Naracoorte Caves National Park is loaded with awe-inspiring relics.

This prehistoric playground is not only home to loads of incredible stalactites and stalagmites, but is also littered with the remnants of 500,000 year-old megafauna!

But beyond its subterranean caverns (the one-hour guided tour of Victoria Cave is a great place to start), you'll also find some amazing short walks up on the surface, including the 2.2-kilometre (1hr return) World Heritage Hike and a 700-metre (30 min return) Roof Top Loop Walk via Bat Cave and Blanche Cave.

Tantanoola Caves.

Ancient and awesome, the Tantanoola Caves Conservation Park is one of few wheelchair accessible caves in Australia, and as those who’ve scratched beneath the surface can attest… it’s also one of the most spectacular!

This subterranean stunner was stumbled upon by a 16-year-old boy after his rabbit-finding ferret disappeared down a hole while hunting back in 1930.

Left behind by the retreating sea hundreds of thousands of years ago, the surreal stalactites and wedding cake formations are as colourful as they are prehistoric, with a kaleidoscope of peach, pink, brown and cream awaiting those who venture down under.

Mount Shank.

As Mount Gambier's eldest sibling, Mount Shank stands proudly at 100 metres above sea level.

Take the 2 kilometre walk around this dormant volcano's rim and you'll enjoy unrivalled views of the city of Mount Gambier and Limestone Coast plains.

The cone-shaped form of Mount Shank is a rare Australian example of volcanic activity in recent geological times, and a genuine South Australian geological wonder.

White Kangaroos.

For those who love things all soft and cuddly, Bordertown is home to Australia's only colony of white kangaroos, who've been hanging out at Bordertown Wildlife Park since the 1980's. Contrary to popular belief, these kangaroos are not actually albino, but are in fact a white strain of the Western Grey Kangaroo.

Cute as they are kooky, you can stroll the perimeter of the park to watch these gorgeous marsupials hanging out with their Western Grey counterparts in a natural environment.

All the Nature you need.
