Glass House Mountains National Park

Glass House Mountains National Park is a heritage-listed national park at Glass House Mountains, Sunshine Coast Region, Queensland, Australia. It is also known as Beerburrum Forest Reserve 1. It is 70 km north of Brisbane and consists of a flat plain punctuated by rhyolite and trachyte volcanic plugs, the cores of extinct volcanoes that formed 26 million to 27 million years ago. The mountains would once have had pyroclastic exteriors, but these have eroded away.

The national park was established in 1994. On 23 June 2010 the Queensland Government announced the expansion of the park to include an additional 2,117 hectares. It was added to the Queensland Heritage Register on 3 May 2007.
