Away from any city glow, the Serengeti sky on a clear night is genuinely startling, with the Milky Way visible as a dense band overhead and thousands more stars than most people have ever seen at once.
New moon nights are the best for stargazing, when the sky is at its darkest, while a full moon washes out fainter stars but bathes the plains in enough light to make out shapes moving in the distance, which has its own appeal.
Many camps, including ours, keep the fire going late for exactly this reason. Wrapped in a blanket with a hot drink, it's common for a ten-minute look at the sky to turn into an hour.
If you're interested in the detail, ask your guide, many can point out the Southern Cross, Orion and the bright band of the Milky Way, and some camps can arrange a telescope on request.
