Most people visit the western circuit to track chimpanzees in Gombe or Mahale Mountains National Park. These two chimp reserves on the shore of Lake Tanganyika offer the best chimp tracking in Africa. Getting here is expensive and time-consuming and is mostly done by chartered plane from Arusha. Instead of visiting one of the chimp reserves as an add-on to a safari in the north, you can combine it with a safari in Katavi, which is the savannah reserve in the western circuit and probably Tanzania's least visited park. Not for lack of wildlife, though. This park offers excellent game viewing in the dry season with superb wilderness appeal, which will make you'll feel like you own the place.
