Trollskogen, Nature reserve in Borgholm Municipality, Sweden.
Trollskogen is a large nature reserve in Borgholm Municipality featuring diverse habitats ranging from ancient pine forests with contorted trunks to coastal grasslands and boulder beaches. The reserve spans approximately 800 hectares and includes sections of oak woodland scattered throughout the protected area.
The site gained official protection in 1998 when the Swedish government designated it as a nature reserve to safeguard its rare ecosystems and Iron Age archaeological deposits. This decision acknowledged the scientific importance of the ancient forests and their layered history.
Local traditions center on the ancient oak trees and mysterious ground features that have inspired folk stories for generations. Visitors can sense how these natural elements remain part of the identity of the surrounding communities today.
Well-marked trails with varying difficulty levels guide visitors through the reserve, with information boards in multiple languages describing local plants and wildlife. Sturdy footwear is recommended, and visitors should be prepared for uneven ground and potentially wet conditions.
The reserve harbors around 300 fungal species and over 150 types of lichens, including rare varieties that thrive only on very old trees. This diversity makes the forest exceptionally valuable for researchers and observant visitors exploring the forest floor.
