The Great Migration is one of the most extraordinary wildlife events on Earth, with over two million wildebeests, zebras, and gazelles journeying across the Serengeti in search of greener pastures. A Great Migration safari in Tanzania provides the chance to witness this awe-inspiring event up close. Depending on the time of year, visitors can experience calving season in the southern Serengeti, thrilling river crossings at the Grumeti or Mara rivers, or the animals’ return to the northern plains.
