Tantanoola Caves, South Australia - A Beautiful Underground Cave

Tantanoola Caves may be one of the smallest caves in South Australia, but what it lacks in size it more than makes up for in beauty. Located near the town of Tantanoola on the Limestone Coast, this single-chamber cave is around 30 metres wide and 8 metres high, yet it contains some of the most intricate and impressive cave formations in the state. With dazzling displays of stalactites, stalagmites and delicate helictites twisting in all directions, Tantanoola Caves offer an unforgettable underground experience in a compact and accessible setting.

Guided Cave Tour Experience

All visits to Tantanoola Caves are via a guided tour, which lasts around 30 minutes. The tour begins with your guide explaining the history and geology of the cave, including how its remarkable formations developed slowly over thousands of years.

Once inside, you’re free to wander around the chamber at a relaxed pace, take photographs and admire the sheer density of formations. Because the cave is small and well lit, it’s easy to appreciate the fine details — from slender stalactites hanging from the ceiling to intricate crystal formations growing seemingly sideways. Tantanoola is often described as one of the most visually stunning caves in South Australia, despite its modest size.

Up and Down Rock and the Cliff Top Walk

Tantanoola Cave forms part of Up and Down Rock, a prehistoric marine cliff that tells an even older story above ground. A clifftop walking track allows visitors to view this ancient limestone formation from above.

During the Pleistocene epoch (around 2.6 million to 11,700 years ago), powerful waves repeatedly battered this coastline. Over time, the force of the ocean carved out sea caves, cliffs and overhangs, shaping what would later become the Tantanoola Cave system.

When sea levels dropped and the land rose, the ocean retreated, leaving behind evidence of its presence inside the cave — including pebbles, shells and seal bones embedded in the rock. These remnants provide a fascinating link between the cave and its ancient coastal origins.

Accessibility and Facilities

One of the standout features of Tantanoola Caves is how accessible it is for visitors of all abilities. Facilities at the site include:

Wheelchair-accessible cave tour
Toilets and disabled toilets
Large car park with long bays suitable for caravans and motorhomes
