Landahl Park Reseve features 8 miles of hiking trails near Blue Springs, MO.
From I-70, head north on MO-7, then take Truman Road 2 miles west. Follow the signs for the "Lake City Range", which is the shooting range. The shooting range butts up against the bike trails, but don't freak out - you are not going to get shot.
