Mammoth Cave is the longest running tourist cave still in operation in the area. It is also the biggest of all tourist caves between Margaret River and Augusta. A short passage leades to a huge chamber with only little decorations. Further in the cave the numer of speleothems increases, but this is not a dripstone cave.

The tour through Mammoth Cave focuses on cave palaeontology and geomorphology in the region. Paleo work carried out in Mammoth has revealed specimens of many of the extinct mega-fauna, some are over 35,000 years old. The remains of a Tasmanian Tiger (Thyiacine) were dated at 25,000 BP. There are no guided tour but visitors get a MP3 audio self-guiding system.
