Canopy walkways are bridges between and 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 scientist who conduct canopy research. After they turned out to provide a limited one-dimensional access to the trees, they were abandoned for canopy cranes. Today they serve as ecotourism attractions, such as the canopy boardwalk in Dhlinza Forest, KwaZulu-Natal, South Africa.
