Gunns Plains Cave

Gunns Plains Cave is a limestone show cave located at Gunns Plains in the Central Coast Council area of north-west Tasmania, Australia. Discovered in 1906, it is renowned for its extensive calcite formations including stalactites, stalagmites, flowstone and shawls along an underground river passage. Operated as a guided-tour attraction, it features a 275-step descent, glow-worm displays and well-preserved formations, making it one of Tasmania's most visited cave systems.

Visitors can expect a guided tour only experience through a single large limestone cave system accessed via 275 steps. The tour follows a well-lit underground river passage with stalactites, stalagmites, flowstone, shawls and calcite formations, including glow-worms in darker sections. The cave maintains a constant temperature of around 9°C. The site includes a visitor centre, ticket office and picnic area set in a rural valley surrounded by forested hills.

Discovered in 1906 by Bill Woodhouse while mustering cattle, who entered through the cave entrance after noticing his dog disappear. Opened to the public shortly after and developed as a show cave with lighting and pathways. Managed by the Gunns Plains Cave Board and later state authorities, it has operated as a guided tourism cave for over a century and remains one of Tasmania's earliest developed show caves.
