Umpherston Cave or Umpherston Sinkhole was formed by the collapse of a chamber of the big cave system below Mount Gambier. It was named after James Umpherston who started to cultivate it and lived on a property nearby. He arrived in 1860, and was a foundation member of the Show Society.
The depression is fertile, with more topsoil and more moisture than outside, which makes it an ideal place for a garden. The area is well developed, with floodlight in the night, terraced gardens, barbecue, toilets and picnic grounds. A display on the steps down into the sinkhole explains the history of the place. Another display in the gardens outside the sinkhole explains the logging history of the area, with a Mack logging truck and an old bull-dozer on display.
Umpherston Sinkhole is very popular at dusk, when possums come out to be hand fed.
