National Geographic put together a list of what they reckon is drives one should take. Quoting from them:
Sometimes it’s the journey, sometimes it’s the destination—and sometimes, it’s both. National Geographic Traveler has scoured the globe for the world’s most beautiful, interesting, and off-beat road trips. Dive in to get drive directions, quizzes, photos, and more.
They included drives in Italy, Canada, Hawai, America and much more. However I could not find any from South Africa. Here I immediately think of paces like the Sani Pass. Are there any that you think should be on this list?
