Safari first usually creates a natural rhythm
Early starts and active wildlife days pair naturally with a slower beach finish. Your international flight pattern may still make another sequence more practical, so routing should come before assumptions.
Avoid making Zanzibar a token stop
A very short beach stay can disappear into airport transfers and check-in time. Decide whether Zanzibar is mainly recovery time, a resort stay or a place you also want to explore, then allocate nights accordingly.
Treat the flight connection as part of the itinerary
The best connection depends on where your safari ends and the available flight pattern for your dates. A well-designed route minimizes unnecessary backtracking and protects useful safari and beach time.
Seasonal conditions, park rules, fees, flight schedules and availability change. A dated itinerary should confirm the details that matter for your trip.
