Beneath the Northwest: Exploring Gunns Plains Caves
A cool, close-up karst adventure a short drive from Burnie — geology you can walk through.
You push open the heavy gate and the air that meets you is cool and close, smelling faintly of limestone and leaf mold. Light from the entryway slides across smooth rock, revealing icicle-like stalactites and the rounded columns where stalactites have met stalagmites over centuries. The tour guide’s voice drops a notch and the cave answers in a hush — a space that has been patient long before humans mapped its corridors. That stillness is part of the draw at Gunns Plains Caves, a compact but charismatic karst system tucked inland from Burnie on Tasmania’s northwest coast.
Trail Wisdom
Wear grippy, closed-toe shoes
The cave path includes stairs and slick stone; hiking shoes or sturdy sneakers reduce slip risk.
Bring a light fleece
Temperatures stay cool year-round (around 12–14°C), so a warm layer makes the visit comfortable.
Use a tripod for photography
Low-light cave photography benefits from a small, sturdy tripod and long exposures; avoid flash on glowworms.
Respect the formations
Don’t touch stalactites or stalagmites — oils from skin can stop mineral growth and damage formations.
Local Knowledge
Hidden Gems
- •Leven Canyon rim walk — dramatic river gorge a short drive away
- •Local farm stands on the Burnie–Gunns Plains route for fresh produce and coffee
Wildlife
platypus (in nearby waterways), glowworms in darker cave niches
Conservation Note
Visitors are asked to stay on paths and avoid touching formations; local groups monitor the karst to limit impact and preserve delicate cave features.
The limestone of Gunns Plains formed from ancient marine sediments; the caves have been a local visitor attraction since the early 20th century.
Seasonal Guide
spring
Best for: wildflowers on the drive, moderate crowds, cool cave temperatures
Challenges: changeable weather, muddy roads after heavy rain
Spring brings wildflowers along the drive and mild temperatures; expect occasional rain and muddy patches on nearby trails.
summer
Best for: long daylight hours, combining coast and inland trips, family outings
Challenges: holiday crowds, warmer car journeys to the site
Summer is busy but offers long days to pair the cave with beaches and nearby canyon walks; go early to avoid crowds.
fall
Best for: clear light for photography, cooler air, fewer visitors
Challenges: shortening daylight, chillier mornings
Autumn’s crisp light suits photography and quieter visits, though mornings can be cool and daylight fades earlier.
winter
Best for: tranquil visits, dramatic weather on the drive, consistent cave temperature
Challenges: short days, possible wet or icy road sections
Winter is quiet underground — the cave’s steady cool becomes welcome refuge, but plan for wet roads and less daylight.

Common Questions
How long is the guided cave walk?
The guided route covers roughly 500 meters of path and includes stairs; plan for a 1–2 hour visit including any interpretation and time for photography.
Are the caves suitable for children?
Yes—the route is family-friendly but includes steps and some uneven surfaces; supervise young children and consider strollers unsuitable due to stairs.
Do I need to book in advance?
Booking policies can vary seasonally; check the local visitor information or attraction website for current tour times and reservation requirements.
Is the cave temperature cold?
Inside temperatures remain steady around 12–14°C (54–57°F) year-round, so bring a light jacket even in summer.
Can I see glowworms in the caves?
Some sections host bioluminescent organisms; avoid using flash or bright lights near them to protect the display and the creatures.
Is the site wheelchair-accessible?
The main walking route includes steps and uneven surfaces, so it is not fully wheelchair-accessible; contact local management about possible alternative access options.
What to Pack
sturdy shoes (for traction), light insulating layer (cave cool), tripod (low-light photography), water bottle (stay hydrated)
Did You Know
