This period is generally regarded the best time to visit Tanzania (in fact, most of East Africa). These months are hot and dry – the best conditions for wildlife sightings. This is because the grasses are short and the vegetation is not as dense, which makes it much easier to spot animals. In the hottest parts of the day, the animals will travel down to rivers, and congregate around any permanent water that is still available.
Although you can see the migration herds throughout the year in the Serengeti National Park, during these months, the herds are found in the northern part of the park. They usually cross the Mara River in the months of July and August, although this depends on the seasonal rains and conditions each year.
Northern Serengeti is much quieter than the central and southern plains. This is due to the accessibility, and the fact that there is much fewer accommodation
