With plenty of blahblah .. blah KirstenBosch Botanical Garden in Cape Town is promoting the new Canopy Walk. Their budget is unlimited and whatever financial loss they make the South African government is paying the bills. The trees at Kirstenbosch (still a beautiful garden in its own right!) are relatively young and, partly, plantation trees. The visitors of Kirstenbosch will walk over the trees and looking straight forward see the backside of Table Mountain which shape from that side is everything except a table..
How different is it in the Eastern Cape (near Plettenberg Bay along the Garden Route) where the Canopy Walk is located in an ancient forest with trees of over 800 years old and you walk partly under the canopies of indigenous/endemic old timers like Yellow Wood and Iron Wood. In nearby Nature Valley there is also a Board Walk (free of charge). Both are from a botanical and nature aesthetic point of view far more interesting than their new born cousin in Cape Town.
