Visited this Mini Amusement Park on Easter Sunday, they have a huge egg hunt for the kiddos every year.
I'd say perfect for ages 3-8, there is a carousel, a train that you can ride around the park, food, ice cream, etc. Absolutely a fun afternoon with the family. ..I'd stay for at least a few hours to make the prices worth it.
Just don't go when it's super hot, there's barely any coverage (besides by benches/food)
