The much anticipated Treetop Walkway through the Arboretum in Cape Town's Kirstenbosch Botanical Garden is now open to the public. Located 11 metres above the ground, the galvanised steel and timber structure offers breathtaking views from the treetops. The project, a collaboration between Mark Thomas Architects and Henry Fagan & Partners consulting engineers, has been nicknamed Boomslang - a large, highly venomous African tree snake - due to its elevated, twisting form. Check out the stunning photographs by Adam Harrower, a horticulturist at the garden, after the break.
