Umpherston Sinkhole

The Umpherston Sinkhole (or the Sunken Garden) is one of the renowned gardens and caves located in the neighbourhoods of the Mount Gambier region.

The sinkhole was once a typical limestone cave formed due to the corrosion of limestone rocks by the waves of sea water. The sinkhole was naturally created when the chamber’s roof collapsed by some natural calamity.

Presently, the Umpherston Sinkhole is a beautiful sunken garden that offers a perfect setting for guests to enjoy and spend some time with their loved ones.

The Umpherston Sinkhole was originally prettified by James Umpherston in the year of 1886.

The sinkhole is open from dawn to dusk; as the sun sets, the Umpherston Sinkhole comes alive with the fascinating possums as they come into this tranquil garden to feed.
