Direct answer
The Mara is best for witnessing dramatic Mara River crossings, typically late July through September when 1.5 million wildebeest concentrate in Kenya's dry-season grasslands. However, the migration is a year-round clockwise cycle — calving in southern Serengeti (January–February) and Grumeti crossings (May–July) are equally spectacular with fewer tourists. For river-crossing drama specifically, the Mara edges ahead; for the full annual cycle, Serengeti covers more ground.
