The Rockies are the spine of North America and are home to cougars, wolverines, wolves, and grizzly bears. Native American tribes compete in breakneck horse races, and daredevil wingsuit fliers leap from mile-high cliffs.

The highest mountain range on earth, the Himalayas form a unique landscape. Its frozen forests and villages hold snow leopards and monkeys, as well as Ancient Buddhist monasteries and athletes compete in the gruelling Everest Marathon.

The longest mountain range in the world, the Andes are home to astonishing hidden worlds, where puma, spectacled bears, and bizarre shape-shifting frogs live throughout its mountains and valleys.
