Gunns Plains Cave

Gunns Plains Cave is a limestone cave system in Tasmania with underground passages extending over 500 meters that contain formation chambers, flowing streams, and natural light filtering through openings. Visitors descend 54 concrete steps to enter and explore chambers filled with geological features.

Bill Woodhouse discovered the cave system in 1906 while tracking a possum that disappeared into a hole in the ground. This chance finding led to the initial exploration and later development of the site for visitors.

The area takes its name from Ronald Campbell Gunn, a Tasmanian botanist who documented local plant life. This connection to scientific exploration reflects the region's history of natural discovery.

Guided tours run daily at scheduled times throughout the year, providing a structured look at the cave system. The pathways are lit and fairly straightforward to walk, though the staircase descent at the entrance requires some effort.

The cave holds one of the largest known shawl formations, defined by thin, curved sheets of calcite hanging from the ceiling. This delicate feature demonstrates the slow geological processes that have shaped the site over thousands of years.
