Wife and I went about a year ago. We drove from Vegas and approached from the south, and had booked a helicopter tour. We got to the town about an hour before the tour, and the airport is south of the canyon as well -- all that is to say, the first time we ever saw the canyon was actually when we flew over it in a helicopter. The ground just falls out below the copter and was one of the craziest experiences of my life seeing that for the first time from above. Bucket list moment for sure
