The wow factor: One of nature’s geological marvels, the Grand Canyon is vast – stretching along 277 miles (446 kilometres) of the Colorado River in Arizona, up to 18 miles (29km) wide and over a mile deep (6,000ft, 1,829m) from rim to river. The Grand Canyon National Park covers an area of 1.2 million acres (493,077 hectares), more than 1,900 square miles (4,931 sq km). www.nps.gov/grca

Did you know? A trip to the bottom of the canyon and back, either on foot or by mule, takes two days, while hikers take three days to get from the North Rim to the South Rim, one way. A Colorado River raft trip through the Grand Canyon takes at least two weeks.

Experience: Step out onto the U-shaped glass walkway of the Grand Canyon Skywalk which juts out from the rim at the Hualapai Nation’s Grand Canyon West and look down 4,000ft (1,219m) to the canyon floor. Grand Canyon West entrance tours cost $29.95 plus fees and tax and a Skywalk add-on costs $29.95. Stay overnight in a cabin facing the canyon rim for $129.95 plus taxes. A Grand Canyon Overnight Getaway add-on from Las Vegas, flying in a Heli USA helicopter below the canyon rim and over Hoover Dam and Lake Mead, to stay in a log cabin at Grand Canyon Ranch Resort after a post-dinner campfire singalong, costs £389 plus $50 fees with Trailfinders. www.grandcanyonwest.com, www.heliusa.com, www.trailfinders.com
