Northern Roslagen: From deep forests to open sea

By Malin Norman | Photos: Destination Östhammar

Northern Roslagen attracts visitors with a rich ironworks history – this is where the Swedish economy was built – as well as a vibrant flora and fauna, and a far-reaching archipelago.

Easily accessible, just an hour from Arlanda Airport, northern Roslagen stretches from the deep mines of Dannemora in the west to the outer archipelago islands in the east. In the north, you will find the Örskär lighthouse, and in the south is the Hargs Mill, built in the 1630s.

This region is bursting with contrasts – from a rich industrial heritage, traditional ironworks and stunning mansions, to picturesque small coastal towns and the stunning archipelago. There is room to breathe, time to explore, and freedom to move as you please. Visitors have plenty of stories to discover, tracks to follow, and traditions to experience.

The iron ore that built Sweden

Dannemora mine is one of the most important iron mines of all time. Iron ore has been mined here for several hundred years. Gustav Vasa, King of Sweden 1523-1560, saw the importance of having access to iron for weaponry and export, and thanks to the excellent quality, it became one of Sweden’s most important exports.

The iron ore was processed by the mills in Österbybruk, Lövstabruk, Forsmark, Gimo and Harg, and then shipped as bar iron via Öregrund. Hence, it is known in the world as Öregrund iron. A visit to Österbybruk is a must, as this is one of Sweden’s best-preserved ironworks, founded in 1643. The ironworks bear witness to a bygone area, and at the Vallon Forge, you will get a vivid experience of the history of ironworking.

Today, Österbybruk is buzzing with life, with exhibitions in the manor house, a magnificent garden and orangery, art galleries and shops, and an active community culture. For instance, you can solve riddles with the help of an audio guide where historical characters give you clues, or watch an opera performance.

Deep forests and exceptional hiking

A highlight in northern Roslagen is the dam called Stordammen, which was built by royal order in the 17th century, when Österbysjön and Dynsjön were dammed up to form a large lake. Set off on the 14-kilometre trail which follows the historic dam embankments built to hold back the water. You will walk by the water and through forests and open marshes, whilst also experiencing history.

The Gimo Mill was also built in the early 17th century, and the charming buildings in the village are still reminiscent of its heyday. There are many hiking opportunities here too, such as the five-kilometre Vallon Trail, with signs of the mill’s history. If you want to go on a longer hike, a 12-kilometre loop of the Upplandsleden trail goes around the Gimo dam, starting at Hammaren.

On the island of Gräsö, you can hike along winding paths, paddle amongst the many islands in the beautiful archipelago, or explore art and culture. The island carries traces of ancient settlements as well as more modern farming history. Gräsö gård is an example of a well-preserved agricultural cultural environment, and today this is both a nature reserve and a visitor centre.

Coastal vibes and Roslagen’s soul

Northern Roslagen is a coastal paradise, all year round. In summer, you can plunge into the sea from sun-warmed cliffs and paddle between islets and skerries. And in winter, you can glide on long-distance skates across frozen lakes.

The coastal towns of Öregrund and Östhammar both tempt with charming boutiques, cosy cafés and restaurants with sea views. Öregrund is a vibrant summer destination, where you can also watch the sun set in the sea. From here, it is easy to venture further into the archipelago to islands such as Gräsö, Örskär (the northernmost point in Roslagen) and Rävsten. In the quieter town Östhammar, you can rent a kayak and explore the archipelago. And, of course, enjoy ice cream from the Swedish champion in gelato, Schrams Gelato.

Another recommendation is stopping by a local farm to get a taste of Roslagen, or stepping into a museum or an art gallery where the contemporary meets the timeless. Explore traditions and cultural heritage, mixed with nature and exciting adventures, and learn more about Roslagen’s wild and peaceful soul.
