Located near the National Capital Region of Delhi, this upcoming district houses numerous multinational companies and as a result, has plenty of tourist-friendly malls, hotels and restaurants. The area's top attraction is the Sheetla Mata temple, a popular pilgrimage site named for the Indian goddess who could dispel small pox; a festival is held there in March and July. For a more rural setting, visit nearby Sohna, which is surrounded by ancient ruins and known for its hot springs.

Maybe your local zoo has lions, leopards, zebras or elephants. Maybe they even have wildebeest. But we bet they don't have 1.3 million wildebeest—never mind 1.3 million wildebeest in migration, with predators in hot pursuit. It's one of the most awesome sights in nature, and you can see it at Masai Mara in southwestern Kenya.

The largest game reserve in South Africa, Kruger National Park is basically a synonym for the word "safari." Home to over 500 bird species, 100 reptiles, nearly 150 mammals, multiple archaeological sites, and a stunningly diversity of trees and flowers, Kruger is the country’s flagship national park. Adventurers can explore the park in a 4x4, take a bush walk or fly above in a hot-air balloon.
