In the beautiful karri forest of the Leeuwin Naturaliste Ridge, hidden in the depths of Jewel Cave, the largest calcite straw stalactite of any show cave on Earth stands at a staggering 580 centimetres. Jewel also lays claim to being one of the biggest show caves in Australia, sinking to a reachable depth of 42 metres and stretching for 1.9 kilometres and, remarkably, it’s also one of the world’s youngest caves.
You’ll find this gem just 37 kilometres south of Margaret River or, if you’re driving up from Augusta, it’s just nine kilometres to the north, along Caves Road. In the soft golden glow of spotlights, the sheer magnitude and beauty of Jewel Cave’s formations leave all visitors awe-struck. The first descent, down a long and narrow tunnel, brings you to the top of the first giant cavern and makes for a breathtaking introduction to the rest of the tour.
During early exploration of the cave, another extraordinary treasure was discovered, in the form of an ancient Tasmanian tiger fossil. One is on display in the spectacular interpretation centre that features iPad technology and a cafe with stunning forest views.
