Trollskogen
Kalmar län
Trollskogen is a protected nature reserve located at the northeastern tip of Öland, Sweden, forming part of the Ekopark Böda. The reserve is renowned for its ancient, wind-sculpted pine trees near the Baltic Sea shore and a rich mixed coniferous forest featuring trees up to 200 years old, as well as rare oaks and junipers. This diverse habitat supports a wide range of rare and threatened species, including unique lichens like the Öland spotted lichen and rare vascular plants such as Baltic wormwood. The area retains traces of traditional grazing, which helps maintain its open and species-rich forest character. Archaeological remains such as burial mounds and stone settings testify to human presence dating back centuries. Notably, the reserve features historical military fortifications from the 15th century and a 230-meter-long stone wall likely used for hunting during the reign of Johan III. Visitors can explore several marked trails with educational signage and visit Naturum Trollskogen, an interpretive center housed in historic forestry huts offering exhibitions on local flora, fauna, and cultural history. The reserve also preserves the Trolleken, possibly Öland's oldest oak, estimated to be 800-900 years old and protected as a natural monument. With its combination of natural beauty, biodiversity, and cultural significance, Trollskogen offers a captivating experience for nature lovers and history enthusiasts alike.
