On the way from Arusha to Serengeti, I had the chance to camp on the rim of the Ngorongoro Crater – and how cool was that! At night you hear the animals that are somewhere around you, and, just after arriving, two elephants visited the Simba Campsite looking for water (from the water tanks). The facilities, both restrooms and dining area, are very basic. The camping grounds are not fenced in, and therefore there are armed guards (in case of animals). A campfire was built after dinner. Even though there are a lot of people, it never felt cramped. Just remember to bring warm clothes, as it gets cold at night, and ear plugs, as the animals in the neighboring tents might keep you awake…snoring…
