Bucket List SA: Natural wonders of the Limestone Coast

The Limestone Coast is on FIFTY+SA's Bucket List SA for it's beautiful natural wonders waiting to be explored.

The Limestone Coast is home to some of Australia’s most stunning natural wonders. Sinkholes, or cenotes, make up one of the many jaw-dropping things to see, from prehistoric caves to expansive lakes.

Umpherston Sinkhole/Balumbul

The beauty of the Umpherston Sinkhole has to be seen to be believed. Appreciate its size and depth from the viewing platforms at the top of the sinkhole, then walk down into the sinkhole, along the terraces and behind the hanging vines.

This sinkhole, also known as the sunken garden, was once a cave formed through dissolution of the limestone. The sinkhole was created when the top of the chamber collapsed downwards.

Kilsby Sinkhole

Serenely located beneath a private rural farming property, Kilsby Sinkhole is world-renowned as one of the best cenote dive sites due to its crystal clear water and breathtaking visibility.

Scuba dive or snorkel the crystal clear limestone-filtered water with a certified guide. Above the water tours are also available, which explore the history of the cenote and include a tasting of locally made Sinkhole Gin.

Hell’s Hole

According to local legend, the ominously-named Hell’s Hole tucked deep within a forest was discovered long ago by two night-time travellers.

Venture into the pine forests off Glenelg River Road and you will find Hell’s Hole. Take a look down into the cenote from the viewing platform. At first, it may look like deep black water but as you look closer you will start to notice the clarity of the water.
