I spent the summer in Colorado with my husband and daughter. She was 1 and a half around the time we were out there. One of the first places we went to was Cheyenne Mountain Zoo. It was a big hit with her. She already knew some animals from one of her board books such as crocodile, elephant, snake, lion and monkey. The zoo had them all and she loved making her sounds for all of them.
One of the first things to do when you walk in is see the giraffes. AND FEED THEM! The guest viewing area is raised and you walk around one side of their enclosure and get up close and personal. Spend the $2 for a giraffe granola bar. They have the freakiest tounges. My little one sat on her dada's shoulders but wasn't too sure about giving up the treat, but enjoyed watching the other kids do it.
Cheyenne Mountain Zoo boasts to be the only mountain zoo in the world. I would think that having a zoo on the side of a mountain would not be an easy thing to design. It can certainly wear out the guests. There is a tram (we never took it) that makes stops. Our group had 4 adults, 2 toddlers and one baby. You really had to hang onto those strollers when going downhill. Some of the areas get pretty steep, but it was all do-able.
All in all I would give the zoo 4 our of 5 stars. It is well designed despite being on a mountain.
The kids absolutely loved it and we had access to all the animals that we wanted to see. And it is in such a beautiful location, what's not to love?
