Paintsville Lake State Park Campground is a 1.6 mile lightly trafficked loop trail located near Staffordsville, Kentucky that features a lake. The trail is good for all skill levels and primarily used for hiking, walking, and camping.
I walk this trail several times a week. You can basically pick the difficulty level you want. The trail is well maintained and has several routes you can take. Some with hills and some that are mostly flat with very few inclines.
This is a good clean walking trail, walk it several times a month.
