Most of the Tulbagh area's beauty comes from its terrain. While there's a great deal of wide open space (which is good for clearing one's mind), the area is completely surrounded by mountains - which are in some way very comforting. I, like all Capetonians, get a bit weirded-out if all I'm able to see is barren flatness with no mountains in sight. It's difficult to explain really. :)
Take a few moments to browse this satellite image - you'll see what I mean by surrounded!
