Emus and koalas... oh my! These are just a couple of the animals you'll likely spot as you drive through Tower Hill Wildlife Reserve, housed in a dormant volcanic crater. Remarkably, this pocket of paradise was once wasteland, transformed by volunteers. More volcanic history awaits across the South Australian border in Mt. Gambier, home to the crater-filling Blue Lake. Bring your sunglasses, because the lake’s name doesn’t do it justice – the intensity of the hue is blinding. By now you’ll be pretty thirsty, so it’s a good thing the Coonawarra wine region is around the corner. Fancy a world-class cab sav, shiraz or merlot? You’ve come to the right place. Sit down to a wine tasting to fully appreciate the region’s flavours. Your final adventure is deep, in every sense of the word. Naracoorte’s Alexandra Cave is a maze of delicate needle-like stalactites and massive twisting columns.
