Take a walk through the treetops on our Treetop Walk. The Treetop Walk is a 1.5km walk through beautiful warm temperate rainforest with 500 metres of steel walkway nestled in the treetop canopy some 20-30 metres above the ground. The walkway culminates in Knights Tower, a spiral tower that rises to a breathtaking 45 metres above the forest floor. Then there are the thrills and challenges of two confronting swaying springboard cantilevers suspended 25 metres above the forest floor which take guests to the edge of the escarpment. Our Zipline Tour is a unique eco-wilderness adventure that takes place in the magnificent Southern Highlands rainforest. Officially the highest zipline tour in Australia, the Illawarra Fly Zipline Tour involves flying on a series of elevated cable spans and navigating suspension bridges from one tree platform to another 35 metres above the forest floor.
