Remlinger Farms in Carnation, WA is a good family destination. It's a bit pricey so not something you'd want to do every weekend. There are lots of hands-on things for the kids, including rides. We particularly enjoy the fall festival. There is a big pumpkin patch, a hay maze for the little ones, and usually a musical entertainer. They have a decent restaurant but expect a long wait during peak times.
