Northern Circuit
Serengeti, Ngorongoro, Tarangire, and Manyara. All within 6 hours of Arusha by road, all visitable in a single 7–10 day trip. The classic Tanzanian safari — and the right introduction for most first-timers.
Roads are paved most of the way; vehicles are 4×4s; lodges range from $200 to $3,000+ per night. It's the most-visited circuit in East Africa for a reason: nothing else gives you this density and variety in a week.
