This oasis city in the middle of the Nevada desert is the capital of hedonism and excess, and the setting of around 115,000 weddings each year (each proof that, contrary to popular belief, not everything that happens in Vegas stays in Vegas). However, there's more than just casinos and impromptu weddings that make this corner of the world worth visiting. Sites such as the Hoover Dam, Bryce and Zion National Parks and the awe-inspiring Grand Canyon are easily accessible from Las Vegas, so, for a break from the neon lights of city, find some tranquillity in the beauty of the surrounding National Parks. And of course, unmissable if you're anyway in the vicinity, or worthy of a trip all of its own, is the awe-inspiring Grand Canyon: more than one mile deep and up to 18 miles wide in places, with almost five million visitors each year. We recommend escaping above the crowds and taking a helicopter tour of the Canyon, for unparalleled views of this Natural Wonder of the World.
