Kirstenbosch is part of the South Africa's national botanical garden system and unique in that it preserves and displays almost exclusively indigenous plants. The coastal edges of South Africa form the Cape Floristic Region, one of the world's six distinguished floral kingdoms, and the majority of the 9,000 plant species can be found here. The garden's 89 acres exhibit more than 7,000 species from five of the country's six biomes, with a cycad collection.

Beyond the gardens, the estate's other 1,300 acres serve as protected wildlife area, and connect to Table Mountain National Park, making it a no-brainer to extend the day with a hike through natural forest and fynbos (a natural shrubland).
