Girrungun National Park is a National Park in Queensland (Australia), approximately 50 km southwest of Ingham, 110 km north of Townsville and 1,290 km northwest of Brisbane. The park is one of the Wet Tropics World Heritage Area series of national parks, and is a gazetted World Heritage site. The park was originally named the Lumholtz National Park, after scientist Carl Sofus Lumholtz, when it was created in 1994. The Blencoe Falls Section was gazetted as part of Lumholtz National Park in 2000. The name was subsequently changed to Girringun in 2003. On National Parks Day 2010 (Sunday, March 28, 2010) the Queensland State Government announced the addition of 2,810 ha to the park.
This large National Park consists mainly of wet sclerophyll forests, but small pockets of rainforest also exist along the eastern slopes and hilltops. The Seaview, George and Cardwell ranges dominate the landscape, which is strewn with granite debris from a volcanic eruption 100,000 years ago. Perhaps the most well known geological feature in this park is the Wallaman Falls. At 268 m it is the largest single-drop falls in Australia. The park forms part of the Wooroonooran Important Bird Area, identified as such by BirdLife International because it supports populations of a range of bird species endemic to Queensland’s Wet Tropics.
Vehicle access into the forest include the Dalrymple Gap Track, or the Wallaman Falls track. However for most of the park there is only very rudimentary or absent vehicle access. Most of the park is accessible for hikers, but due to its remoteness and rugged terrain only experienced bushwalkers should undertake extensive hikes.
