The USA packs spectacular biodiversity within its borders, boasting some of the most beautiful places in America.

Within the 50 states, you'll encounter incredible natural landmarks, including hot desert playas and plateaus, skyscraping mountain ranges topped by glaciers, rolling grasslands where millions of bison once roamed, tropical rainforests, active volcanic zones and polar tundra.

Many of the USA's most magnificent natural wonders are protected today by the National Park Service (NPS). These specially protected places also provide a safe haven for an astonishing array of wildlife, ranging from tiny eyeless fish living in the dark haunts of Mammoth Cave to the giant grizzly bears of wild Denali National Park. Scattered from coast to coast and beyond, here's our pick of the most mind-blowing of the USA's natural wonders.

The world's tallest trees grow on the fog-kissed Northern California coast. Redwoods can reach a height of 379ft, taller than the Statue of Liberty in NYC, and live for up to two millennia. Almost half of the remaining old-growth redwood trees that have never been logged are protected by the chain of Redwood National and State parks.

Planning tip: To hike the 4.5-mile Tall Trees Trail, you will need to apply for a reservation in advance online.

Peering over the edge of the Grand Canyon is enough of a thrill for some, but to really appreciate the canyon's grandeur, hike all the way down inside it to the rushing Colorado River.

Planning tip: To escape the crowds, visit the canyon's North Rim, which gets a fraction of the visitors at the South Rim. However, beware that the North Rim is seasonal – there are no visitor services and roads close to all vehicles from December 1 to May 14.

Famous conservationist and wilderness writer John Muir called Yosemite nature's temple. Gazing up at towering granite monoliths such as El Capitan and at Yosemite Falls, North America's highest waterfall, you'll know exactly what he meant. Declared a UNESCO World Heritage Site for its unique geological features carved by glaciers, Yosemite also sustains a variety of rare wildlife inhabiting California's craggy Sierra Nevada mountain range.

Planning tip: Yosemite Valley's waterfalls peak in late spring, which is a less hectic time to visit the park than during summer.

Niagara Falls is not just one, but three waterfalls that gush along the US-Canada boundary between New York and Ontario: Horseshoe Falls, American Falls and Bridal Veil Falls. They aren't the USA's tallest waterfalls, but these powerful cascades have a bigger
