The Gloucester Tree is a giant karri tree in the Gloucester National Park of Western Australia. At 58 metres in height, it is the world's second tallest fire-lookout tree (second only to the nearby Dave Evans Bicentennial Tree), and visitors can climb up to a platform in its upper branches for views of the surrounding karri forest. It is owned by the Shire of Manjimup. The wooden lookout cabin was demolished in 1973 for safety reasons, and was replaced with a steel and aluminium cabin and visitors' gallery. Currently the climb is done by stepping on 153 spikes that spiral the tree.
