April is wet in the Serengeti, but you'll love it!
The wildebeest herds move slowly in April through the Serengeti. They leave the Ndutu region and head north-west past Simba Kopjes and toward Moru. These areas are known for their healthy lion and big cat populations. Expect a good dose of interaction between predator and prey.
Safari guide saw a small group remaining in the southern Serengeti while a large group is in the Maswa Game Reserve.
