A fifth of Bornholm is wooded, making it the most forested county in Denmark. Beech, fir, spruce, hemlock and oak are dominant. There are three main areas, each laid out with walking trails (pick up free maps at tourist offices). Bicycle trails connect them all; the beautiful route 22 takes you through Almindingen and Paradisbakkerne.
Almindingen, the largest forest (6000 hectares), is in the centre of the island and can be reached by heading north from Åkirkeby. It’s the site of Bornholm’s highest point, the 162m hill Rytterknægten, which has a lookout tower called Kongemindet from where you can view the surrounding countryside.
A small herd of European bison have successfully been introduced to a fenced enclosure within Almindingen, by Svinemose bog. You can visit the area and try some bison-spotting off Chr X Vej, north of Åkirkeby.
Paradisbakkerne (Paradise Hills) contains wild deer and a trail that passes an ancient monolithic gravestone. It’s 2km northwest of Nexø.
Rø Plantage, about 5km southwest of Gudhjem, has a terrain of heather-covered hills and woodlands.
