Briony Hume heads underground to discover Fox Cave – the most challenging cave found so far in the Naracoorte Caves National Park. Squeezing thru “the Slot” and then through “the Gate” the caves begin to open out into cathedral-like spaces, a spectacle for intrepid adventure caving groups. This 3 hour tour isn’t for the faint hearted but Fox Cave offers the chance to bring out the Indiana Jones that’s been lurking inside you! The fun is in finding out what’s around the next corner, or through that next tunnel.
