The Cape Peninsula and the south-west
Cape Town sits between a 1,086-metre sandstone massif and two very different seas: the Atlantic side rarely climbs above 15 °C, while False Bay on the other side of the peninsula runs several degrees warmer. The mountain is a national park that starts inside the suburbs, so a serious hike and a city afternoon can share the same day.
The surrounding region is the only part of the country with a Mediterranean climate — dry, bright summers from November to March and wet, windy winters from May to August. That inversion matters when you plan: the Cape is at its most reliable exactly when the game-viewing regions in the north-east are at their wettest.
Beyond the city, the Cape Winelands around Stellenbosch, Franschhoek and Paarl sit within an hour's drive, and the Cape Floral Region — one of the world's six floral kingdoms, and the smallest — covers the peninsula in fynbos that flowers through the cooler months.
