Þrastaskogur forest

Thrastaskogur is a beautiful and historic forest area located in Grímsnes- og Grafningshreppur in South Iceland, close to Úlfljótsvatn and Thingvallavatn. It is one of the oldest and most notable forestry and land reclamation sites in the country and has long been a popular destination for outdoor activities and environmental education.

Forestry in Thrastaskogur began around 1905, making it one of Iceland’s earliest reforestation projects. The land is owned by the Icelandic Forestry Association and has served as a research and educational area for more than a century. Visitors can see a wide variety of trees, including native species such as birch and willow, as well as imported species like spruce, pine, and larch.

The forest offers marked walking trails, small ponds, and diverse birdlife, making it a favourite spot for families, school groups, and nature enthusiasts. There are picnic tables, benches, and educational signs throughout the area, providing information about tree species and local ecosystems.

Thrastaskogur has also played an important role in environmental education and outdoor learning. Schools and organisations often use the forest for nature studies, and the Icelandic Forestry Association regularly arranges guided tours and educational events there.

Located about 60 to 70 kilometres from Reykjavík along Road 360 (Þingvallavegur), the forest lies near Úlfljótsvatn and the Ljósafoss power station, both of which are interesting places to visit in connection with a trip to Thrastaskogur.
