This national park is one of the most spectacular in Kenya thanks to its size and the sheer variety of animals it houses. We spend two and a half days here and saw just about everything (although the cheetahs and leopards evaded us). That is also taking into account that we went at the end of the wet season and there was plenty of watering holes for the animals to gather.
We saw tons of elephants, hippos, all kinds of antelope, zebras, enough different birds to fill a book, giraffes, a very rare and shy black hippopotamus, and a spectacular pride of 12 lions which was really worth the effort of finding it. Just incredible.
