Reputed to be the most decorated cave per square meter of any in Australia, it features some of Mother Nature's greatest work including spectacular stalactites, stalagmites, helictites, cave coral and rimstone pools.
The cave is 20 meters underground and approximately 150 meters long. It was formed some 800,000 years ago when river water seeped into a 500 metre long fault line dissolving the limestone and creating calcium carbonate which crystalised when it was exposed to the air. The magnificent formations within the cave have been formed by those crystals and coloured by tannins & minerals from the surface soil carried in by water seepage.

As the moisture drips to the floor below, carbonate adheres to the ceiling and a hollow stalactite is formed. Moisture continues to drip through the stalactite to create a stalagmite building up from the floor.
The cave was discovered by a local farmer, Keith McEachern, in 1936. With the help of three friends, McEachern lowered himself more than 17 metres down a vertical shaft to discover one of nature's great treasures.

Over the next 5 years, McEachern and his friends dug a stairwell through the limestone and opened the site to the public as a tourist attraction, commencing guided tours in January 1941.

Walking through the cave, you can't help but be amazed by the spectacularly coloured formations and mind-blowing timeframe of their creation, but I couldn't help wondering what it was that possessed a man having stumbled across a hole in the ground to tie a rope around his waist and be lowered all that way into a pitch black abyss.
Today the cave complex includes an information centre & kiosk, landscaped surrounds and camping facilities including on-site cabins and caravan sites. A River View Nature Walk leads down to a jetty and views of the Glenelg River Gorge.
