• Many of Indiana's twenty-five state parks feature hiking trails, as well as biking and horseback riding trails. But in most cases, hikers are not permitted on biking and horseback riding trails, and horseback riders and mountain bikers cannot use most of the hiking trails. Hiking trails range in difficulty from easy to very rugged.
