The Hoverberg Grotto (Swedish. Hoverbergsgrottan ) is located near Svenstavik in Jämtland on the southern part of Lake Storsjön in Sweden . It was discovered in 1897 by Jöns Väst in the Hoverberg .
The entrance is wedge-shaped and can be entered via a steel staircase that leads down about 12 meters into a kind of anteroom. From there, another staircase leads down a steep drop into the interior. You enter a cavity that is 20 to 30 meters high. Overall, the cave should have a length of 170 meters. Parts of the grotto were illuminated with green and red light in early 2010.
