We visited the Umpherston Sinkhole in Mount Gambier today. Once a cave formed through dissolution of the limestone, the sinkhole was created when the top of the chamber fell to the floor of the cave, creating its “sunken garden” effect.
The sinkhole was created when the top of the chamber collapsed downwards. Now the topsoil down on the floor of the cave forms the perfect environment for the sunken garden.
Originally beautified by James Umpherston, it is open at all times.
Improvements made by Umpherston included a Victorian residence and gardens. In 1884, Umpherston began to develop the sinkhole as a “pleasant resort in the heat of summer”. At this time a third of the floor of the sinkhole was covered with water. Umpherston died in 1900 at the age of 87, leaving a wife but no children.
The City of Mount Gambier obtained the site in 1994, which was listed on the Register of State Heritage Places in October 1995.
It probably looks more spectacular in spring/summer and in twilight, but even on a winter’s day it’s an impressive sight.
There are barbecue facilities and toilets available.
It’s a pleasant walk from top to bottom and something the whole family can do.
