Umpherston Sinkhole
Description
Umpherston Sinkhole is a large natural depression in Mount Gambier formed by the collapse of a limestone cave roof. Inside, terraced pathways descend past hanging vines and lush plant growth to reveal a sunken garden with ferns and flowering shrubs.
History
The limestone cave that formed this sinkhole was created over thousands of years as water dissolved the rock until the roof collapsed. In 1886, James Umpherston transformed the exposed depression into a publicly accessible garden.
Culture
The sinkhole is also known as Balumbul, reflecting its significance to the local Kaurna people. Since 1886, when James Umpherston developed it as a garden, it has served as a place where visitors come to relax and connect with nature.
Practical
The sinkhole has stepped walkways and ramps for descent, though it is not wheelchair accessible due to steep paths and uneven ground. Visitors unable to climb stairs can still enjoy views from the top, and note that dogs are not permitted inside the garden itself.
Did you know?
Possums come into the sinkhole at dusk to feed, allowing visitors to watch these small animals in their natural behavior. The best time to visit is around sunset when the animals are most active and their habits become visible.
