The Tree-In-The-Rock, after which the site has been named, is just 100 metres along a shaded walk. Extending its roots down through a crevice, this mature karri clings to existence on a granite boulder. Karri and marri are the most dominant trees in this area, while karri hazel, karri wattle and tassel bush form part of the understorey. Australian Bluebell can be recognised by its small bell-like mauve flowers from October to February.
