Northern Serengeti works best as a focused seasonal safari area, usually reached by fly-in routing or as part of a longer Serengeti itinerary with enough time to avoid rushing.
Many travellers visit Northern Serengeti specifically for the possibility of Mara River crossings. Because crossings cannot be scheduled, the route needs patience and at least three nights in the area for a stronger chance of being in the right place at the right time.
Northern Serengeti can be combined with Central Serengeti, Ngorongoro and Tarangire for a complete Northern Circuit safari. It can also connect smoothly with Zanzibar by flight after the safari, especially for travellers who want a beach finish after a more intense migration route.
