The Serengeti is an incredible experience. There is no better place in the world for spotting lions. You don't even have to do anything to see them! You're driving around the park, and there they are - usually lying lazily under a tree flicking their tails from side to side, unbothered by the humans and the cars that may be passing them. Of course, there's also tons of other wildlife -we saw leopards, lots of elephant herds, zebras, giraffes, antelope etc. We stayed for 2 nights, but I would have loved to stay longer.
