Umpherston Sinkhole

Umpherston Sinkhole is also known as The Sunken Garden. It was once a cave formed through dissolved limestone. The sinkhole was created when the roof of the chamber collapsed. Now the topsoil down on the floor of the cave forms the perfect environment for the sunken garden.

Originally nurtured by James Umpherston in the mid 1860’s, the sinkhole is open at all times and from dusk each evening the area comes alive with possums as they venture into the floodlit gardens to feed.

A large undercover shelter with group settings for around fifty people and free barbeque are provided.
