The Centenary Tree Canopy Walkway is a new curved steel and timber bridge that winds and dips its way through and over the trees of the Arboretum. Inspired by a snake skeleton, and informally called 'The Boomslang' (meaning tree snake), it is a low-maintenance, low-impact sculptural raised walkway.The Walkway takes the visitor from the forest floor into and through the trees and bursts out above the canopy, giving spectacular panoramic vistas of the surrounding mountains, Garden and Cape Flats.The planning of the walkway started in 2012. The foundations were laid down in June 2013. Construction of the steel structure started in August 2013 and on-site construction of the framework began in November 2013. It was completed on 16 May and opened to the public on 17 May 2014.
