Hidden away in an ancient marri forest and dripping with dramatic stacalites and stagmalites, Mammoth Cave is mesmerizing sight, but it’s not just the striking surroundings that draw the crowds. The cave hit headlines in the early 20th-century when archeologists uncovered the fossilized remains of ancient Australian Megafauna – gigantic mammals including Tasmanian Tigers and Giant Kangaroos that have been extinct for thousands of years.
Visitors can uncover the cave’s fascinating history on a self-guided audio tour, following the boardwalk circuit through the 500-meter long cavern. Highlights of the cave include unique rock formations like the ‘Karri Forest Flowstone’ and the ‘Mammoth Shawl’, dramatically illuminated by slats of natural light.
Mammoth Cave is located in Forest Grove, 15 minutes drive south of the Margaret River, and is open daily from 9am to 5pm. Admission is AU$22.50 for adults and AU$12 for children.
