I had read such mixed reviews I was a little unsure of this, but we decided to try it on our first morning in Tucson. It was a perfect introduction to Tucson and the surrounding area! Most of the museum is walking trails outside, although there are a few indoor exhibits. All animals are there because they were found either injured or lost, and cannot live on their own. We were there about 3 hours. We learned about the animals, cacti, rock formations, and other interesting facts about the area. There were a few animals we didn’t see in their pens, but most were out walking around. Well worth the money and time spent, and appreciate all the locals who said this is a ‘must do’!
