Gråkallen is Trondheim's second highest mountain top (552 meters height), and it's hemisphered shape is visible from a long distance. From Gråkallen you can see mountain tops from Sweden in east to Trollheimen in south. The top is just a short walk from Skistua. Follow signs and avoid the fenced military area. The ski sport facilities at Gråkallen (Vintervasskleiva) are to be removed, and there are plans for a new winter sport area between Skistua and Kobberdammen.
At the view point on top there is a guide telling which mountain top you may see in different directions.
