Mount Gambier is full of unique geological wonders, and Engelbrecht Cave is definitely one of them. This limestone cave system sits right in the middle of town and offers a guided 30-minute experience that takes you down into its eastern and western sections.

The tours are run by knowledgeable guides, and booking ahead is essential. There’s also a café on site where you can grab something light – if it’s available, the blue lemonade is a quirky local favourite that’s worth trying. It turns your tongue blue! Beyond being a tourist attraction, Engelbrecht is also known in the cave-diving community, making it one of the more distinctive spots on the Limestone Coast.
