This tour was top notch. Our guide, Cory, was great. He was very friendly and knowledgeable. The trip out to the sites from Flagstaff is very long - 2 hours plus. We made plenty of bathroom stops - something that can be lacking on other tours. Cory provided great commentary during the trip. The sites were beautiful - although it was extremely hot. Cory provided plenty of cold water, wet towels to put around our necks, and umbrellas. The tour was arranged so we visited Horseshoe Bend first, earlier in the day since the hike out was longer and unshaded. We were given plenty of time to enjoy the view and take pictures. We visited the Glen Canyon Dam after Horseshoe Bend and had lunch. Lunch was very good and plenty of food: large sandwiches, chips, fresh fruit and pasta salad and soft drinks, served on nice plates - not paper! We then headed to Antelope Valley which was the highlight of the trip. It was during the hottest part of the day but once we were down in the slot canyon, it was quite pleasant. Our Navajo guide did a great job and took great pictures for us. There is a lot of climbing up and down stairs/ladders so I wouldnāt recommend for those who cannot navigate steeps stairs. There are also some very tight places you need to navigate. This tour was one of the best Iāve ever done and I highly recommend it! Bravo!
