O'Reilly's Tree Top Walk allows you to walk through the canopy to see flowering and fruiting trees and vines, the epiphytic orchids and ferns, and the birds and animals that inhabit the tree tops.

The Tree Top Walk is only 300 metres from the Guesthouse via the Booyong Walk, a rainforest boardwalk that was built by the Green Mountains Natural History Association.

The Tree Top Walk, was the first of its kind in Australia, is 180 metres in length and is made up of 9 suspension bridges, with much of the walkway being 15 metres above the ground.
