Mammoth Cave is a natural time capsule, nestled deep in the Margaret River Region, where ancient fossil remains of long-extinct Australian Megafauna were unearthed.

Once home to giant animals that roamed the continent before their extinction around 46,000 years ago, the cave offers a rare glimpse into the distant past. Self-guided audio tours, available in English, French, German, Malay, and Mandarin, enable you to explore at your own pace, as you learn about the cave’s geological formations and fossil heritage.

Look out for the 50,000-year-old zygomaturus jawbone, a relic of a large wombat-like herbivore, still embedded in the cave wall. Wander along the gently sloping boardwalk and stairs through chambers adorned with stalactites, stalagmites, and a stream that flows during late winter and early spring.

On existing the cave, you'll step into a tranquil forest setting where a peaceful walk past towering marri and karri trees completes the experience. Step back in time, uncover stories preserved in stone, and enjoy a visit that blends education, exploration, and natural wonder.

Lovely experience. Must-see place. Natural wonder. Rich history and plenty to learn for both kids n adults. Ample parking. Helpful staff, especially Ocean. Headsets provided for self-operated history lessons. The cave is naturally cooler and the outside world is warmer, especially after climbing a lot of stairs outwards. There is a separate exit for people who don't want to climb those steep stairs. It was a short cardio exercise for an unfit person like me :) There is a short bush walk from the exit of cave back to the reception which crosses the main road, so need to be careful. Plenty of souvenirs available. We will try the other caves next time.
