Hogsback is one of the top birding destinations in South Africa and can easily be reached with a domestic flight to Port Elizabeth, then a 3 hour drive.
The most sought after bird here is the Cape Parrot (Poicephalus robustus) one of two subspecies of Cape Parrot. The other subspecies, (Poicephalus fuscicollis) can be found in the Magoebaskloof area. Cape Parrots are highly endangered and there are several people working hard in this area to try to save them. Cape Parrot Project, World Parrot Trust.
Hogsback has accommodation to suit every budget. Since I have not yet been here (it’s on my 2015 Africa trip) I can’t recommend any particular eco-lodge but there is a good selection on this website.
There are several birding tour operators in the area and links can be found on Fat Birder. You could try Aves or Graham Russell.
