For intercontinental travel, Nairobi (Kenya) is the busiest travel hub in East Africa, though Dar es Salaam (Tanzania) and Addis Ababa (Ethiopia) are also popular. North Americans will likely need to stop off in Europe, as direct flights from the North America to anywhere in Africa are seasonal at best. Nonstop flights are available to the major hubs from London, Amsterdam, Istanbul, Zurich, and many other cities. South Americans will likely connect in Johannesburg, which sees daily nonstop flights from São Paulo; a longer but often cheaper option is to connect in Spain or Italy. Visitors from Asia and Oceania will generally connect somewhere on the Arabian peninsula.
Under the right circumstances, travel costs are competitive with other destinations, so it may be worth experimenting with dates, booking an open jaw flight (for example, arriving in Nairobi and departing from Addis Ababa) or booking short-hop flights separately from the intercontinental flight.
In East Africa, wildlife safaris and adventure travel include sight seeing and wildlife viewing tours to see all Big 5 wildlife animals, chimpanzee, gorilla tracking, wildebeest migration and mount kilimanjaro climbing trips.
