America's great national parks are a genuine highlight for many visitors to the US. The big hitters dominate in epic Grand Canyon – one of the wonders of the natural world – and the otherworldly volcanoes of Yellowstone, regarded as the oldest national park on Earth.
Yellowstone National Park, Wyoming
Just north, in Yosemite, a wilderness of imposing mountains, dense forests and roaring falls pave the way for unforgettable hikes and lodge stays, while the mesas of Monument Valley that rise up from the Arizona Desert have come to symbolise the American West thanks to numerous appearances in film and TV. Less-visited national parks are well worth a visit, too, from Colorado's Black Canyon to Alaska's snow-topped Denali and Alberta's hoodoo-dotted badlands.

Some 34 million hectares has been preserved as National Park in 49 of the 50 USA states, most offering a full range of facilities and lodges alongside and a variety of brilliant outdoor activities to make the most of the spectacular surrounds.
