Natural places

Serengeti National Park, Tanzania

Tanzania’s portion of the Serengeti is the ideal location for an African adventure. Visit between January and March to witness the wonder that is the Great Migration, an iconic phenomenon that sees 1.5 million wildebeest sweep through East Africa on an annual, 1,200-mile cycle.

Salar de Uyuni, Bolivia

Southwest Bolivia’s Salar de Uyuni is the largest salt flat in the world, and is about as surreal as landscapes come. When dry, the flat is a sheet of blindingly white salt tiles. During the wet season, the shallow lake mirrors the sky, creating a dreamy illusion of infinity.

Sequoia National Park, California

This central-Californian park is home to some 8,000 colossal sequoia trees—the gentle giants of the tree world. “General Sherman,” a tree named for the Civil War general, is the hero of these treasured acres: It stands 275 feet tall and 25 feet wide, making it the largest known single-stem tree on the planet.
