Our tour guide, Josh, knew all the best spots for setting up for photos and helped us get some great pictures.
The first two canyons (Grey Owl and Rattle Snake) can only be seen through this tour outfit and we enjoyed them without having to share with anyone else. Both were quite beautiful and fun to go through. Both have some ladders to climb up/down in different spots. So, this isn't a handicapped friendly part of the tour.
The final canyon (Upper Antelope) is open to more tour operators and there were hords of people. Our guide was good about waiting and directing others to allow us to get some of the better photographic opportunities. While some of the areas are narrow, the whole canyon is on one level and easily accessible.
Overall, the canyons were beautiful and we quite enjoyed the experience.
