I'm sure it's used more now that the area has more development, but when I was younger the little lake with a walking path around it behind Burrell on S. National was pretty quiet. It's off of Bradford Parkway, Schaible Lake. Tiny little area between the medical buildings near Cox South. And I'm sure the boy scouts use it plenty, but there's a wooded area with a trail and a pond behind the Boy Scouts building on Eastgate.

If you don't mind the drive/bike ride, there's a little park off of the Frisco Trail as you get close to Bolivar called La Petite Gemme Prairie that I don't think a lot of people know about. It's literally just a few acres of prairie. Probably pretty beautiful with spring flowers soon.
