It’s not termed the "Small Serengeti" for nothing – Liuwa Plains does in fact host the second-largest Great Migration on the continent, when the wilderness throngs with between 40,000 and 50,000 harrumphing blue wildebeest. Combined with the vast, china-blue skies and waving grasslands, you could be excused for thinking you really were in the Serengeti, although perhaps a rather more wild and remote version, without the hordes of people.
