Ngorongoro in June
June is arguably the optimum month to visit Ngorongoro Crater. The long rains should be over, but the scenery will still be green and lush, and the safari circuit remains relatively uncrowded, as peak tourist season only starts to kick in towards the end of the month or into July. Looking further afield, it is also a good month for Zanzibar beach holidays and Kilimanjaro climbs, and for catching the Serengeti migration as it moves northwest towards the Grumeti River. There are no real negatives other than that the crater rim will be pretty chilly (average daily maximum 19°C and nightly minimum 8°C) and the avian variety is relatively low.
