We'd come to South Africa's Western Cape to see the Kirstenbosch Botanical Gardens and dive with sharks ( ... my wife's idea of relaxing) before beginning a month traveling in Africa in earnest. We worked in a couple of days relaxation (my idea of it) in between the two. We'd heard from a number of folks that your first trip to Africa should be to South Africa. I suspect they meant your whole first trip, but three or four days should suffice, shouldn't it? Having spent a few weeks exploring, we understand what they mean, ... and would likely offer the same advice, especially if you're not a terribly experienced traveler. South Africa has much of the infrastructure and a rhythm familiar to westerners, but with glimpses of something a little rawer, deeper. It's a great place to get your African toes wet.
We'd decided to spend a couple of relaxing days out in the Fynbos, a mountainous coastal region covered in low heath. By itself this small area, one-sixth the size of our home state of Colorado, represents one of the Earth's six major floral kingdoms. More than 9,000 species of plants occur in this tiny area, two-thirds of them occurring nowhere else. (By contrast, the Holarctic Floral Kingdom covers pretty much the entire northern hemisphere.)
The hiking was spectacular right out of our back door, with trails running up the valleys, looping over ridge lines, and soaring out across high natural benches. We saw relatively few birds in the higher open heath, but drainage bottoms, with their larger shrubs and the occasional copse of trees, teemed with them. Below a young Neddicky (best guess) alights on a Red Pagoda plant (best guess).
The Cape Sugarbird (below) is one of six species of bird endemic to the Fynbos. They occur nowhere else in the world, but were a common sight amongst the shrubs here.
If you do have the good fortune to make it to the Fynbos for a few days, we can highly recommend the cabins at Kolkol Mountain Lodge. Only an hour outside of Cape Town, they felt wonderfully isolated and remote, and in many ways were: fifteen minutes down a dirt road, and another kilometer up an even narrower double track. It's worth trying to arrive before dark if you can.
Just down the hill there's a wildlife sanctuary, Cornell Skop Farm, which does indeed have a number of lions in its care. Lions which have been known to carry on a bit after the sun goes down.
