Mammoth Cave

This natural time capsule offers an extraordinary insight into Australia’s ancient past.

Mammoth Cave has wheelchair access to the first chamber. Pick up your MP3 self-guided audio tour to get started; available in English, German, French, Malay and Mandarin.

Entering the cave through bushland via a gently sloping boardwalk, you’ll realise just how much there is to see here. Over 10,000 fossils had at one time accumulated inside the cave; upon excavating, many of these were found to be remains of Australian Megafauna (giant animals) that became extinct around 46,000 years ago.

Even a 50,000-year-old ‘zygomaturus’ jawbone is embedded in the cave wall.

If you visit during winter, you will see a stream flowing through the cave, which is stained red from natural tannins.

After emerging above ground, the optional bushwalk back to the guide’s station offers visitors the chance to enjoy the magnificent marri and karri forest surrounding the cave. The Marri Walk Trail is one of few walk trails in the South West offering the rare opportunity to explore a regenerating forest. Flourishing new growth lines the path edges and climbs the trunks of the towering trees.

For your safety and the protection of the recovering forest, please keep to the designated walking trail at all times.
