Nestled within the stunning karri and marri forest, Mammoth Cave is a site of incredible natural and historical significance. Once home to ancient fossils of Australia’s megafauna—giant animals that roamed the Earth before their extinction around 46,000 years ago—the cave offers a fascinating glimpse into the past. Don’t miss the 50,000-year-old zygomaturus jawbone, a relic of a large wombat-like herbivore, still embedded in the cave wall. Your visit concludes with a scenic walk through the serene marri and karri forest.
Self-guided audio tours, allow you to explore at your own pace while learning about the cave’s fascinating history and natural features. A gently sloping boardwalk and stairs guide you through the cave, where you’ll encounter crystal stalactites, stalagmites, and a seasonal stream that flows through the cave during late winter and early spring. As you exit the cave, stairs lead you into a tranquil forest setting. The tour concludes with a peaceful walk through the marri and karri forest.
