There aren’t too many national parks whose main attraction is bats. But lushly forested Kasanka is the focal point of a migration comprising up to 10 million straw-colored fruit bats. Visit between October and December, and it’s truly exhilarating to watch these enormous bats erupt from their daytime roost in the evening, or return there at sunrise. At other times, the main attraction is the opportunity to photograph the rare swamp-dwelling sitatunga antelope from a strategically located hide.
