Undara Volcanic National Park

Mount Surprise, Etheridge Area

In the vast open spaces of the savanna, a sea of seasonal grasses conceals the Undara lava tube, one of the Earth's longest flows of lava originating from a single volcano. Ribbons of green remnant rainforest contrast with the surrounding dry savanna landscape, marking the course of sections of the lava tube. Caves within the tube sections are fertile pockets where rainforest plants and animals thrive.

Take a guided tour to the lava tube caves. Spend a pleasant afternoon walking around the rim of Kalkani Crater, an extinct volcano. Explore the self-guided walking trails throughout the park, ranging from short walks to a 12 kilometre return hike, following a section of historic telegraph line. Ride your mountain bike on the longer trails. Watch the sunset, while clouds of bats exit the lava tube caves. Accommodation and camping are available at the nearby resort. Access to the lava tubes is by commercial tour only.
