the treetop walkway:

its construction at the Kirstenbosch Botanical Garden (South Africa) will be finish by March and with the formal opening to the public in April. 


The walkway meanders through the Arboretum, also known as the Enchanted Forest, in the Kirstenbosch Botanical Garden. The 130 metre long walkway is made from galvanised steel and timber, and will stretch 11 metres above the ground. Due to the snake-like twisting, the skeletal structure and its position above the trees, the walkway has been given the nickname ‘Boomslang’.





Kirstenbosch National Botanical Garden, against the eastern slopes of Cape Town’s Table Mountain, there are over 7 000 species in cultivation, including many rare and threatened species. Kirstenbosch lies in the heart of the Cape Floristic Region, also known as the Cape Floral Kingdom. In 2004 the Cape Floristic Region, including Kirstenbosch, was declared a UNESCO World Heritage Site – another first for Kirstenbosch, it is the first botanic garden in the world to be included within a natural World Heritage Site. Kirstenbosch is the largest of a country-wide network of nine National Botanical Gardens administered by the South African National Biodiversity Institute (SANBI)




The pathway will wind and curve through the branches and tree trunks in much the same way as a boomslang or tree snake would do.
  • The structure is comprised of a structural spine and ribs, inspired by the form of a snake’s skeleton.
  • When completed, the walkway will take visitors from the forest floor through the foliage of the tree tops and eventually ascend above the canopy to give spectacular views across the mountain.
  • It will be 11 meters above the ground.
  • The walkway is envisioned as a sinuous, lightweight, non-intrusive steel structure.
  • It will have a slatted timber deck.
  • The galvanised steel structure will be painted to attract moss and growth.
  • The structure will be supported  by steel columns intertwined with creepers.
