What is the best time for a private Serengeti safari from Arusha?

The Serengeti can be visited throughout the year, but the best time depends on what you want to experience. June to October is generally popular for dry-season wildlife viewing because animals are easier to spot around water sources and vegetation is less dense. The Great Migration can be experienced at different times of the year in different parts of the Serengeti, so there is no single month when the migration is everywhere. If your main goal is the migration, your itinerary should be planned around the expected location of the herds rather than simply choosing the most popular safari season.
