We spent a wonderful day in the company of Larson, our guide. Our morning tour visited the valley and with Larson's help we viewed all the usual sights you would see on the drive through, but also visited special spots, which are not available without a guide. It is impossible to describe the majesty of the valley up close or the wonder of being close to drawings that are thousands of years old on sites that people have inhabited for all those years. Larson was knowledgeable and happy to share that knowledge with us, without a constant running patter that some guides impose upon you. It was a magical morning. The afternoon tour varied from what was planned due to a road closure, but no matter, we visited 17 room house, on a site that allowed you to imagine life in the long ago times clearly, again aided by Larson's narratives. We capped things off with a drive through a portion of the Valley of the Gods, which was well worth visiting during which we enjoyed discussing current life in the area and simply being awed by the surroundings.
Kudos also must go to Meisha in the office, who patiently helped us plan things, and cheerfully helped me solve a problem I caused myself by originally booking the wrong date. She was always responsive (email recommended) and very helpful in all regards. A pleasure to work with.
These were real people, really interested in helping you understand and enjoy your experience. Highly recommended. Take a private tour if you can manage it, you will not regret the expense.
