The Greenheart Canopy Walkway has eight tree platforms more than 15 metres above the ground with a ninth, a two-storey platform, on a free-standing tower reaching more than 22 metres in the air. The longest bridge is 50 metres long. The total length of the walkway is 308 meters. Construction is as non-invasive as possible using the patent pending ‘tree hugger’ suspension system. The tree hugger uses no nails or bolts or intrusive fasteners of any kind, using instead, a variable tension system to provide the least amount of infringement or impact on the trees.
