This time I will explain you another circular route. But pay atention. Its 19km takes around 6h. Then I would not start this route if you are not prepared.
The path is not difficult itself. And there are not a lot of cross. So it isn't easy to get lost. However, 19km are too much and the cumulative altituded is around 800m. Because of these reasons I would classify this route to high level.
