The vertical Fell Kellostapuli is Ylläs' noble little sister. This sharp edged little sister plays hard to conquer: from three directions its slopes are so steep and quarried that only experienced hikers manage to wander from the feet of the mountain to the top.
The Kallostapuli is like a DaVinci code puzzle, with the morning reflection revealing the easiest route to the top. The slope on the side of the rising sun, i.e. the eastern slope, allows this beauty to be conquest with a smile.
