The usual phrase is blaze a trail , and it meant to mark a route through the woods by cutting notches in the bark of trees to show the way. Create a path is similar in meaning, but blaze a trail would not necessarily involve making any significant improvements to the route, such as making it possible for wagons to use, merely marking where it was. Now blaze a trail is often used figuratively to mean to lead the way in doing something that hasn't been done before.
