Chobe National Park, in the north-east of Botswana, is renowned for its enormous herds of elephant and buffalo and the prides of lion that stalk them. In the green months, game migrates to the open grasslands of Savute and the south. From April to November, as water becomes increasingly scarce, animals head back to the permanent waters of the Chobe River in the north. Literally thousands of elephant and buffalo take refuge on the river islands. The Chobe riverfront, with pods of hippo, large crocodiles and rich birdlife, is just a short overland transfer to Victoria Falls - a perfect add-on to any safari.
