Cumberland Mountain State Park
This state park is in Crossville, Tn. It has many great walking paths that are perfect to do with children. I have found that you have to be careful when choosing which hikes to go on with kids. This one is not too steep, or strenuous. The path goes around the lake and never gets boring. Wildlife is everywhere you look. I suggest you do not try and eat your lunch near the geese. This park has three playgrounds and alot of places to sit and picnic. It is definitely a must see if you are visiting.
