It may be 300 miles away from the strip, but if you’ve come this far, it pays to take a side trip out to this amazing natural wonder. You can DIY it, or try one of the many tour companies — you can head out in luxury SUVs, basic buses or vans or even helicopters and planes. Among the top-rated options are the 15-hour van tour by Grand Adventures, though this includes a 3-mile hike, so it’s best for families with older kids (or parents who are willing to carry a toddler around in a backpack, and Sundance Helicopters, which offers a number of helicopter and plane tours of the Grand Canyon and includes anything from a sweeping tour of the canyon’s rim to a champagne picnic on the canyon floor. And since most of the aerial tours get you there and back in just a few hours, they make a better (though much pricier) option for younger kids.
