We visited Marakoopa Cave on our drive from Sheffield to Cradle Mountain. It was a bit of a lucky dip time-wise but we were extremely happy to have a personal tour for two of Marakoopa with Aaron, a passionate Mole Creek Caves tour guide. There are two tour guided options at Marakoopa - Underground Rivers and Glow-worms or the Great Cathedral and Glow-worms Tour. We parked in the visitor centre carpark and took the 10min Fern Glade Walk up to the assembly point. We thoroughly enjoyed the tour and the walk through our geological history. The crystalline formations were magnificent and the glow worms (aka lava) were evident. A thoroughly fascinating and informative tour!
Notes:
You can park and walk to the cave via the Fern Glade Walk or drive to the tour assembly point
Amenities are located at the visitor centre
Admission charges help fund maintenance, ground improvement and general upkeep

This is the bigger of the two caves. With heaps of steps. Should be fine for everyone.

The guide didn't explain much about formation in this cave. The guide at the other smaller cave was much better at explaining it.

At the entrance there's a section with glow worms, but photography not allowed as they're sensitive to lights (other parts of the caves are ok to photograph)

We had planned on hiking to some falls this day but it was raining so the car was a good alternative. You buy your ticket at a visitor center then either walk or drive to the cave. It is pretty chilling in the cave so wear a coat. Our guide was just average and could have been better. It was something to see once.
