Even at this scale – the huge expanse of the Kalahari's Salt Pans are visible as a blue-white splodge, just below the relevant bubble. Zoom in by one level on the scale to see the Okavango delta more clearly, entering Botswana in the north-east (where the 'Okavango Panhandle' marker is), and then fanning out. It's in this area that most of the main safari camps are.
Click onto any of the markers, and follow the links in the bubbles, for maps of these areas with precise locations for the various safari camps and lodges.
