Chobe National Park is Botswana's first national park, and also the most biologically diverse. Located in the north of the country, it is Botswana's third largest park, after Central Kalahari Game Reserve and Gemsbok National Park, and has one of the greatest concentrations of game in all of Africa. The park is noted for having a population of lions which prey on elephants, mostly juveniles or subadults.The park is widely known for its spectacular elephant population: It contains an estimated 50,000 elephants, perhaps the highest elephant concentration of Africa, and part of the largest continuous surviving elephant population. The elephant population seems to have solidly built up since 1990, from a few thousand. Elephants living here are Kalahari elephants, the largest in size of all known elephant populations
