Built to commemorate the Kirstenbosch National Botanical Garden's 100th anniversary in 2013, the 'Boomslang' is a 130m canopy walkway discreetly located in the tree tops of this famous garden's arboretum. It offers striking views of the garden, the mountain and beyond, and should not be missed.

Did you know?

In 2004 the Cape Floristic Region, including Kirstenbosch, was declared a UNESCO World Heritage Site.

Tucked away between some 430 trees, visitors to the Kirstenbosch National Botanical Garden should not forego the opportunity to traverse the Boomslang, an arboreal ‘bridge’ that offers stunning views over the garden and the mountain.

The Kirstenbosch National Botanical Garden is often described as 'the most beautiful garden in Africa' for its magnificent views, showcasing the exceptional biodiversity of the Cape's flora. It is also home to many birds and animals, and the walkway offers the opportunity to enjoy birdlife at tree level.

The walkway was built to commemorate Kirstenbosch’s 100 th year in 2013 but, due to construction delays, only opened to the public in May 2014.

It is a steel-and-timber structure of 130m, starting at ground level and rising to some 12m above the ground. Because it’s crescent-shaped, the walkway ends a short distance from the start. It is also suitable for wheelchair users.

Its ingenious design makes it a sinuous structure that winds its way through the trees – like the indigenous tree snake it is named after that is rarely seen on the ground.

In an act of ‘bio-mimicry’, the outer steel frame resembles the rib cage of a snake enclosing the wooden bridge and looks a bit like a roller-coaster ride for pedestrians.

Construction had to take account of the sensitivity of the site; every tree in the arboretum was surveyed and drawn on a 3D map so that the path of the walkway could be plotted without causing any harm to the trees.

In fact, one tree was accommodated by cutting a hole through the bridge's timber – and it is now known as the ‘hugging tree’, which is sure to be a hit with children.

During assembly, the contractors brought in 6m lengths of the prefabricated steel structure to be bolted in situ, while the foundations were hand dug and filled in with reinforced concrete pads.

Throughout, the contractors were under strict instructions to keep the site squeaky clean so as to prevent harm to this mature part of the garden.

The walkway is located in the arboretum area of the garden, close to the cycad garden on the one end, and the concert lawn at the other.

Visitors to the garden do not have to pay an additional fee to use the Boomslang, but those who do not have a head for heights, or who might be put off by the slight sway of the curved steel bridge, might decide to sit this one out.
