From Northern Europe's largest castle ruin to four unique round churches and Denmark's finest sandy beach: Bornholm packs remarkable variety into 588 square kilometres. Here are the highlights you shouldn't miss — with honest tips on what's really worth it.
Perched on a 74-metre-high rocky outcrop in the north of the island stands Northern Europe's largest medieval fortress. Over 800 years of history, mighty brick walls and sweeping views across the Baltic make Hammershus Bornholm's most-visited attraction.
Admission is free all year round. A modern visitor centre with an exhibition and café tells the castle's story. The ruin is most impressive at sunset, when the sun sinks over the sea.
Bornholm has four of Denmark's eight round churches. These whitewashed fortified churches were built in the 12th century with walls over two metres thick — to protect the island's people from pirate raids. Their bell tower stands separately in the churchyard.
Østerlars is the largest and oldest (from around 1150), Nylars is known for its medieval murals, Ols Kirke is the tallest and Ny Kirke the smallest of the four. All are still in use and free to visit.
Bornholm's landscape is as varied as the island itself — rugged granite coasts in the north, dense forests inland and dramatic rock formations by the sea.
The Helligdomsklipperne rise up to 22 metres from the sea, riddled with caves. The echo valley Ekkodalen lies in Almindingen, Denmark's second-largest forest, home even to free-roaming bison. At the northern tip, Hammeren offers stark rocky terrain with wide views.
In the south, the finest sand slopes gently into clear water; in the north, wild bathing coves await among the rocks.
Dueodde is the most famous beach: powder-fine white sand, often called the finest in Europe, with the island's tallest lighthouse. Balka, with shallow warm water, is especially family-friendly, while Sandvig and Boderne in the north are wildly romantic alternatives.
Colourful half-timbered houses, narrow lanes and small fishing harbours — Bornholm's towns invite you to stroll, stop and explore.
Svaneke wurde 2013 zur schönsten Kleinstadt Dänemarks gekürt — ein Künstlerdorf mit Galerien und der Brauerei Svaneke Bryghus. Gudhjem staffelt rote Dächer zum Hafen und ist Ausgangspunkt für Bootstouren nach Christiansø. Rønne, die Inselhauptstadt und der Fährhafen, lohnt einen Bummel zu jeder Jahreszeit. So kommst du per Fähre an →
Smoked herring is Bornholm's culinary emblem. In the smokehouses with their white chimneys — in Gudhjem, Svaneke or Allinge — you can try "Sol over Gudhjem": smoked herring with egg yolk, radishes and chives.
Add island specialities like liquorice from Lakrids by Bülow, beer from Svaneke Bryghus, sweets from the candy workshop and the soft-serve ice cream found at almost every harbour. For gourmets, the island even offers Michelin-starred dining. More on the island's food & smokehouses →
Northeast of Bornholm lie the Ertholmene, popularly called the "Pea Islands". The largest, Christiansø, is the North's oldest sea fortress — laid out in the 17th century to defend against Swedish attacks and today entirely protected as a heritage site.
Excursion boats cross from Gudhjem or Allinge. The car-free island, with its old fortress walls and peaceful atmosphere, is a special experience. In high season, get to the harbour early — spots are in demand.
Bornholm has around 235 kilometres of cycle paths — paved routes, forest tracks and MTB trails. A route of over 100 km circles the island almost without a climb, one of the most cycle-friendly in Europe.
For families there are experiences from the Medieval Centre and the butterfly park to NaturBornholm. And Bornholm is famous for its crafts — ceramics, glass and historic windmills like the one in Årsdale, still working today.
The Hammershus castle ruin, the four medieval round churches (especially Østerlars), the sandy beach of Dueodde with its lighthouse, the Helligdomsklipperne rock formations, the echo valley Ekkodalen and the coastal towns of Svaneke and Gudhjem with their smokehouses are among the main highlights.
Many of the finest attractions are free: Hammershus, the round churches, the beaches and the cycle paths cost nothing. Museums, boat trips to Christiansø and individual experiences usually cost between 50 and 120 Danish kroner per person.
There are four medieval round churches: Østerlars (the largest and oldest, from around 1150), Nylars, Olsker and Nyker. They were built in the 12th century as fortified churches to protect against pirate raids.
Bornholm ist klein und hat rund 235 Kilometer Radwege fast ohne Steigung — die Insel gilt als eine der fahrradfreundlichsten Europas. Viele Gäste erkunden sie mit dem Rad. Ein Auto bietet mehr Flexibilität, und ein Busnetz verbindet alle Orte. Mehr zur Anreise per Fähre und zu Unterkünften.
Yes. Christiansø is the North's oldest sea fortress and part of the Pea Islands northeast of Bornholm. Excursion boats run from Gudhjem or Allinge. In high season you should get to the harbour early, as places are limited.
Plan your journey, find a bed by the sea and take your time — the island rewards those who stay.
