The Tree Top Walkway and Booyong Boardwalk was a Bicentennial project started in 1975 by the Green Mountains Natural History Association. The project was initiated by Pete O’Reilly who had seen something similar in his overseas travels and realised, at that time Australia had nothing like it and so Green Mountains became the first location in Australia to offer a Tree Top Walk structure. Built by members of GMNHA and the many supporters of the project, with funding from grants, donations and supporters. All sections of the boardwalk that exist today, have taken the GMNHA until 2018 to be fully completed. The aim was to provide an interpretative experience, accessible to all ages and abilities by placing the viewer in a birds eye view of the canopy typical of the rainforest environment within the Lamington National Park.


The boardwalk takes you from ground level observation of the forest, to the start of the Tree Top walk, traversing nine suspension bridges for 180 metres at approximately 15 metres above the rainforest floor. Spot epiphytic orchids and ferns surrounded by the many birds and animals that inhabit the treetops. Profiles depicting the local rainforest flora have been placed along the walkway to assist with identification.
