Cape Point is only about 30 miles from Cape Town, but the drive can take anywhere from one to two hours, depending on how many times you stop. A full day driving tour of the peninsula allows time to see seal island of Hout Bay, the penguins at Boulders Beach, the Cape of Good Hope, and Kirstenbosch Gardens.
One important piece of trivia -- although many people think that the Cape of Good Hope is the southern tip of Africa and the dividing line between the Indian and Atlantic Oceans, that distinction actually goes to Cape Aghulas, which is about 100 miles east. Cape of Good Hope is the southwestern tip of Africa.
As these photos show, a day at Cape Point is a definite "must see" when you visit Cape Town. It's a beautiful area, with diverse wildlife like baboons and African antelope.
