help Barker Cave (Undara) FAQ
Where is Barker Cave located?
Barker Cave, also written Barker's Cave or Barkers Cave, is part of the Undara lava tube system in Queensland's Undara Volcanic National Park. It is reached through the remote North Queensland park rather than through an urban cave attraction.
How did the Undara lava tubes form?
The Undara volcanic flow formed about 190,000 years ago when the surface of a lava stream cooled into a crust while molten lava continued draining beneath it. The empty channel later became a system of caves, including Barker Cave. [Queensland Parks](https://parks.qld.gov.au/parks/undara-volcanic/about)
Can visitors explore Barker Cave without a guide?
Access to the Undara lava tubes is by guided tour only, both for visitor safety and for protection of the cave environment. Tours are arranged through operators such as Discovery Resorts Undara and other approved providers. [Queensland Parks visitor information](https://parks.qld.gov.au/parks/undara-volcanic/things-to-do)
What wildlife can be seen around Barker Cave?
The Undara caves support insectivorous bats, while collapsed entrances create sheltered habitat for rainforest plants and animals. Visitors may also see signs of predators such as spotted pythons waiting near cave entrances when bats emerge.
