This article is posted under South Africa but of course the Transfrontier Park, as its name suggests, is in three countries, Namibia, Botswana and South Africa. 

The Kgalagadi (or Kalahari) Transfrontier Park is an excellent place to see desert animals, particularly lions and if you like sleeping out in the open then the camping on the Bostwana side of the park takes some beating. 

When you enter the park you effectively leave one country and are then in no mans land until you leave through a gate into another country (Although note that if you want to go into Botswana you first have to get your passport stamped at the Three Rivers checkpoint in South Africa.)  The South / Southwestern side of the park is managed by the South African Parks Department and their excellent website can be used to book accommodation.  The North of the park is managed by the Botswana Parks department so booking is a nightmare but the camps are so nice it is worth the effort getting a place if you can.

There are two good tracks which run through the park from Twee Riven (Two Rivers) camp, one goes to the Mata Mata border crossing with Namibia and the other to Nossob camp and beyond.   These two roads follow valley floors and are easy to drive in any vehicle.  The other roads go up into the hills for which you need a 4x4 or at least a car with a high ground clearance.

For this reason the two good tracks can be quite busy, as soon as you break off on the more difficult routes then you can expect to be on your own, particularly the tracks which link the Botswana side with the rest of the park.  One thing to watch.: When you book  you are advised to bring your own firewood.  If you drive in from the Namibian side your car will be searched and any firewood confiscated!

Because it is a desert and the food not as plentiful as in Kruger or Etosha the game viewing takes a bit more effort but it is well worth the time and trouble and it will be an experience you won't forget in a hurry. 

The camp sites on the Botswana side are very isolated, each pitch is about 1km from any other, which makes it a wonderful 'away from it all' experience but not for people who are worried about being eaten by lions.
