The aerial pathways are created using over 2km of three-tiered vine-like ropes that link up to nine 20 -25m high support structures – massive trunk-like cylindrical poles. Three of these poles have inside areas with ropes and ladders for the orangutans and siamangs to climb through and up to the top and out onto the ropes - that extend from the high canopy habitat right out over the zoo’s lake - Auckland Zoo’s website
