You drive up to the Raptor Facility first. It's free, simple, and has some beautiful specimens. We did not attend one of their weekend shows, but they do educational presentations on the birds. A volunteer helped us to find some of the birds that were hiding as well as tell us some of the personality quirks of the birds. They are birds that cannot be released to the wild.
After that, my husband and I were not very impressed with the Nature Center. It was basically a park area with a trail and a restaurant. The memorial garden is still being set up for the spring. We didn't learn of any of the activities for the weekend until I saw a flyer in the bathroom as we were leaving. The information center/gift shop workers didn't greet us or inform us.
