This network of trails is very well thought out. Something for everyone. Hard to get lost because you are between the road and the lake on most of the trails. Nice hardpack trails that dry fast. Campground at park plus nearby Lodging in Cambellsvile. Email if you need more info!
From I-65take hodgenville exit just south of Elizabethtown. Head for Highway 210. Take 210 all the way to Cambellsville and watch for signs to Green River Lake state park
