It is between Mount Gambier and Millicent in South Australia. It takes around 20 minutes from mount gambier while driving towards Millicent.
Hi, it is right on the main highway between Millicent and Mt Gambier.
It is on the highway halfway between Mt. Gambier and Millicent. DO NOT take the turnoff to Tantanoola township, the cave itself is on the highway, not in the town.
