Undara Volcanic National Park

Undara Volcanic National Park is a nature reserve in Queensland featuring an extensive network of underground lava tubes that wind through the landscape. These caves were created by ancient volcanic activity and remain the park's most distinctive geological feature.

The volcanic formations in the park originated roughly 190,000 years ago when molten lava flowed from the Undara crater and carved out the underground tunnel system. This geological event shaped the landscape structures that define the area today.

Indigenous Australian communities maintain connections to this land through ceremonies and traditional practices, passing knowledge about the geological formations across generations.

The park offers guided tours through the lava tubes with varying difficulty levels for different visitors. Plan your visit between March and December when regular tour operations are available, and on-site accommodation is provided for those wanting to extend their stay.

The tunnel system here is the longest of its kind on Earth, surprising visitors with the massive underground dimensions they encounter. The caves offer an unexpected sense of spaciousness and openness beneath the surface.
