Entrance to Camp Sparrow as seen in the animated series
Camp Sparrow is the camping ground in the Huldrawood. Along with Scout Hall, it is one of the two private properties owned by the Sparrow Scouts.
The camp is visited once a year during the annual end-of-year-camp. The clearing in the woods has room for multiple tents. The section of the Huldrawood where the camp is, is still within the walls of Trolberg, and according to Raven Leader in "Hilda and the Black Hound", the camp is fenced off on all sides.
