Umpherston Sinkhole, Mount Gambier

Must see · Geologic Formation · Nature / Park
Once a limestone cave, Umpherston Sinkhole was created when the cave ceiling collapsed. The sunken earth proved a perfect place for growing lush greenery. Thick vines cascade over the sinkhole's edge while the center is landscaped with grasses and palms. Take a walk through the garden for an otherworldly look beneath the green curtains and between the limestone rocks.
