Kissing the east side of Table Mountain (and used as a starting point for its hardcore climbers), Kirstenbosch is one of the world’s most biodiverse gardens and a leader in conservation science. The sprawling site contains incredible forms of flora and near-endangered plants that have been cultivated since the early 1900s. Explore at ground level or up above along The Boomslang, a treetop walkway with views for days. Don’t leave without visiting the beautiful sculpture garden, which includes a bust of Nelson Mandela and breathtaking Mambo sculptures carved from opal stone.
