Three teenage boys, my wife and I did the mule assisted trip with our guide Omar and it was beyond fabulous! Deaing with Four Seasons was a pleasure from start to finish. The guys in the office were friendly, organized and patient. Omar was the perfect balance of style and substance. Loads of fun with lots of knowledge. The boys, who are all high school athletes and my marathon running wife all loved the hike up. I am a 5 times a week, 50 year old, modestly fit gym rat, and the hike up was a challenge. I made it to the top tired and happy, but take the warnings seriously – strength and fitness are critical to enjoying this trip. The food was excellent camping food and the equipment was first rate. Previously, I stood on the rim of the Canyon, helecoptered over the Canyon and rafted the Canyon – still, hiking it still was beyond great. If you can…GO!!!
