I went on October 16 to take a family's photos and it "closed for the season." There is a small parking lot just outside of the park, so we left our cars there and walked in.
The fall colors here are GORGEOUS. So many yellow leaves on the trees and the ground. We saw plenty of places to camp with picnic tables and a grill at each site. There's also bathrooms and a playground. And plenty of people were out running, biking, longboarding, etc on the trail that goes through the park (Jordan River Parkway).
