About Hallormsstaðaskógur
Hallormsstaðaskógur is Iceland’s largest forest and one of the country’s most unusual outdoor landscapes. Native birch woodland at Hallormsstaður was protected in 1905, making it Iceland’s first national forest. Today the forest contains an extensive network of walking trails, cycling routes, picnic areas, playgrounds, an arboretum and camping areas beside Lagarfljót.
Our practical tips
