Tip: All adults and children need to wear socks. Half of the museum is designated for children 4 and younger (Artville) and socks (no shoes nor bare feet) must be worn in this part of the museum. There are lots of fun play things for small children in this area. They have story time at 11am on weekdays.
The exhibits in the other part of the museum are diverse, with the special exhibit being a train exhibit at this time. Outside of the building are several percussion musical instruments. There is a small gift shop and eating area. Everything is on a single floor.
Admission is $8 for anyone over 1 year old, but since I am a member of the ACM (Association of Children's Museums) admission was half price ($4 per person) for the 6 people in our party.
Not the best children's museum I have ever been to, but not the worst either.
If I were going to spend a few hours in a museum with children, I would probably continue on down the street a couple of blocks to the Arizona Natural History Museum. It has a larger diversity of exhibits and appeals to more age groups.
