Canopy walkways - also called canopy walks, treetop walks or treetop walkways - provide pedestrian access to the forest canopy. Early walkways consisted of bridges between trees in the canopy of a forest; mostly linked up with platforms inside or around the trees. They were originally intended as access to the upper regions of ancient forests for scientists conducting canopy research. Eventually, because they provided only limited, one-dimensional access to the trees, they were abandoned for canopy cranes. Today they serve as ecotourism attractions in places such as Dhlinza Forest, KwaZulu-Natal, South Africa, Taman Negara National Park, Malaysia, Sedim River, Kulim and Kakum National Park, Ghana.
The Kendeda Canopy Walk in Atlanta, Georgia, USA is a more recent variation that provides visitors with the ability to move through a 180-metre-long (600 ft) section of urban forest at an elevation of 12 metres (40 ft). The walkway construction is a somewhat unusual reverse suspension design.
Canopy or treetop walkways are especially popular attractions in Australia. They can be found in most states and a variety of environments.
