Serengeti National Park, Tanzania

14,763 km² Serengeti hosts the Great Migration of 1.5 million wildebeest and 250,000 zebra annually — the largest land animal movement on Earth. This Tanzanian reserve harbors 70 large mammal species and 500 bird species, offering unmatched predator-prey dynamics. With a lion population density of 0.6 per km², it outperforms #2 Masai Mara's 0.5 per km² for big cat sightings. Cheaper than the average safari destination at $200 per day for camping, the Serengeti remains the crown jewel of African safaris, delivering a wildlife spectacle that dwarfs all rivals in scale and diversity.
