Grand Canyon National Park, Arizona
We were in the US for nearly a month and this was definitely the highlight of the trip. The Maverick helicopter company did a fantastic job and the flight over the Grand Canyon was something that we could all recommend to everyone.
We also bought the DVD images and were very pleased with the fact it was our tour with our comments and the pilot had made sure to capture the images.
I can't recommend this experience highly enough. A must if you are going to the South rim.
