As there are no higher mountains nearby, there is a nice view over Trondheim, the fjord and mountain ranges—Trollheimen to the south and Sylane (which is partly in Sweden) to the east.
The name ('the home of the trolls') was proposed by Håkon Løken and used by Trondhjems Turistforening in the 1880s, and is considered a "tourist name" (there was no single name for the entire area before).
