Came here during a weekday for my birthday as a fun mom-son day date and it was super cute! Very happy they participate in the museums for all program also! A few of the exhibits were broken but my son had a wonderful time! We will definitely visit again! It was a bit crowded for a weekday, but still a lot of fun!”

Perfect idea for a rainy day! There is so much to do for my almost 3 year old. Place is clean and updated. Wonderful learning opportunities in every field for children! They also have a small area for babies. It’s wonderful to see the joy on each child’s face at the museum!”

Such a great museum for children. My kids are 3 and under and they had a blast. There is so many different rooms and things for them to do. Love how they make science interesting. Also bathrooms are child friendly with step stool and they have a healthy snack machine which I have not seen before. I highly recommend this museum and can’t wait to go back!”

This is a really great place to bring children of any age. My daughter was a little over a year and we played with a four year old. Both of them had a blast. We stayed about 4 hours, they spent the entire time excited and playing.”
