The Western Cape in South Africa is one of the best places in the world for a week's long road trip (which should cover MOST of the sites). You can do a plethora of activities around Stellenbosch and Cape Town like surfing at Strand and Muizenburg, see penguins at Boulder's Beach, drive the scenic Chapman's Peak, hike Lion's Head during the full moon, and dine at the V&A Waterfront.
