Gunns Plains Caves
Located 30 kilometres south of Ulverstone in northwest Tasmania, Gunns Plains Caves is an impressive limestone cave system that sits within the scenic Gunns Plains State Reserve. Spanning ten hectares, the reserve has been protected since 1918, making it one of Tasmania’s earliest cave reserves.
Discovered in 1906 by local hunter Bill Woodhouse, the cave system quickly gained attention for its striking formations and hidden underground river. Today, it remains a go-to destination for locals and tourists, celebrated for its stunning calcite shawls, flowstone and delicate glow-worm displays.
Caves In Tasmania
Tasmania is home to many cave systems, each offering unique geological and ecological wonders. Among these, Gunns Plains Caves stands out for its accessibility, natural beauty, and engaging visitor experience. Unlike some remote or rugged caves, Gunns Plains is family-friendly and suited to those with a moderate level of fitness. After descending 54 concrete steps, visitors follow a mostly level path through 275 metres of underground passages, with only one short ladder section to navigate.
The cave was formed by an underground river that still flows today. Along the way, you may spot freshwater crayfish, fish and even eels moving through the water. Look closely at the sandy riverbanks—platypuses are known to sleep and nest here, adding to the cave’s natural charm.
What sets Gunns Plains apart from other Tasmanian caves is its living environment. Beyond its glistening crystals and calcite formations, the glow worms—tiny bioluminescent insects—cast a magical blue-green glow across the walls, creating a surreal atmosphere children and adults alike will find mesmerising.

Gunns Plains Caves has guided tours, offered daily at six intervals between 10:00am and 3:30pm, providing both educational insight and personal stories that bring the caves to life. Passionate local guides explain how the caves were formed, describe the minerals on display, and share tales from the early days of cave exploration in the area.
The tours typically last around 45 minutes and are suited for visitors of most ages, although they are not recommended for individuals with significant health or mobility concerns due to the stairs and damp conditions. Comfortable, flat-soled shoes are essential for a safe and enjoyable visit.
The site is particularly appealing for families. Children are often fascinated by the glowing worms and shimmering formations, while adults appreciate the serenity and natural beauty of the environment. The small size of the groups ensures that the tours are personal, interactive and enjoyable for all ages.
Just outside the cave, the surrounding countryside provides further opportunities to unwind and explore. Nearby, visitors will find camping grounds, local accommodation and cafés offering regional produce and warm hospitality. It’s a perfect base for a weekend escape or a peaceful family holiday in Tasmania’s north west.
