First Time in Bornholm? 8 Things to Do

You’ve probably heard whispers about Bornholm—Denmark’s rocky gem floating in the Baltic Sea—but you’re not quite sure what all the fuss is about. Here’s the thing: this island doesn’t need expensive tours or fancy hotels to win you over. From ancient castle ruins that won’t cost you a kroner to enter, to beaches that rival the Caribbean, Bornholm’s got eight experiences that’ll make you wonder why you waited so long to visit.

Explore Hammershus Castle Ruins at Sunset

While most travelers flock to Hammershus during crowded daytime hours, you’ll get the best experience by timing your visit for sunset. You’ll have Northern Europe’s largest castle ruins practically to yourself, and the dramatic lighting transforms the massive stone walls into something truly spectacular.

The elevated cliff-side position offers panoramic Baltic Sea views that become even more breathtaking as the sun sets behind the medieval silhouette.

Since the site’s accessible 24/7, you won’t pay extra for this premium experience. The evening tranquility lets you really absorb the history of this 13th-century fortress that once controlled Baltic trade routes. This strategic stronghold served various rulers for over 500 years before being abandoned as a fortress in 1743.

Bring your camera – the natural lighting enhances every texture of these ancient stones, creating unforgettable photos without the daytime crowds blocking your shots.

Walk Among the Round Churches Starting With Østerlars

After soaking in those castle views, shift your focus to Bornholm’s most distinctive architectural treasures – the round churches that you won’t find anywhere else in such concentration. Start with Østerlars Church, the oldest and largest from around 1150.

You’ll discover these weren’t just places of worship – they’re medieval fortresses with walls up to 2 meters thick, designed to protect locals from pirate attacks.

Inside Østerlars, climb the internal stairway to explore three defensive levels and marvel at restored 14th-century frescoes depicting biblical scenes. The church stays open daily with free admission, making it budget-friendly.

Don’t miss the ancient runestones and the separate bell tower. The church features a massive hollow central column that’s six meters wide and contains a small interior room called “the oven.” Plan to visit all four round churches for a complete picture of this unique Romanesque architecture that showcases Bornholm’s strategic medieval importance.

Sink Your Toes Into Dueodde’s Impossibly Fine Sand

Once you’ve explored Bornholm’s medieval fortresses, head south to Dueodde Beach where you’ll discover sand so fine it creaks beneath your feet like fresh snow. This white powder-soft sand stretches for kilometers and was once prized for hourglass production due to its uniform quality.

You’ll find free parking on Fyrvejen with accessible wooden boardwalks leading through pine-stabilized dunes. The shallow, calm waters extend 100 meters offshore—perfect for families.

Pack a lunch since nearby restaurants can be pricey, though ice cream shops offer affordable treats. Hidden among the forest paths, you’ll stumble upon German gun batteries from World War II—unfinished Wehrmacht positions that add an unexpected historical dimension to your beach day.

Visit the western section for windsurfing or climb Dueodde Lighthouse for panoramic views. The eastern end features a naturist beach if you prefer clothing-optional sunbathing. This Lonely Planet-ranked destination offers something for all.

Hike the Dramatic Cliffs at Helligdomsklipperne

From Bornholm’s southern sandy shores, head north to discover an entirely different coastal experience at Helligdomsklipperne, where granite cliffs plunge dramatically into the Baltic Sea. These 20-meter-high cliffs between Tejn and Gudhjem offer some of Denmark’s most spectacular hiking along the Kyststien coastal trail.

You’ll navigate forest paths and rocky terrain while spotting unique formations like “The Dry Oven” and “The Black Cauldron” cave. The medium-difficulty hike takes 2-5 hours depending on your route, with parking available in nearby towns.

Watch your footing near cliff edges and pack water since amenities are limited. The site draws its name from a nearby holy spring that once served as a place of prayer and pilgrimage, adding spiritual significance to the dramatic landscape.

End your adventure in colorful Gudhjem for well-deserved refreshments. This free outdoor experience delivers dramatic Baltic views and connects you with Bornholm’s rugged northern character.

Discover Bronze Age Stories at Madsebakke Rock Carvings

While the dramatic cliffs showcase Bornholm’s natural beauty, the island’s human story stretches back millennia at Madsebakke Rock Carvings near Allinge. You’ll find Northern Europe’s most important Bronze Age rock art site, where ancient people carved ships, wheel crosses, and footprints into granite slopes 2,500-3,000 years ago.

Walk carefully around the sloping granite surfaces—don’t step on the carvings to help preserve them. The ship motifs are particularly fascinating, likely representing the sun’s journey or souls traveling to the afterlife. Look closely for animal figures and mysterious symbols, though weathering has made some details faint. The carvings originally appeared as white contrasts against the grey granite, making them much more visible than they are today.

The site’s free to visit, making it perfect for budget travelers. Plan 30-45 minutes to explore this sacred landscape where Bronze Age ceremonies once took place.

Take the Zipline Over Opal Lake

After exploring ancient rock carvings, you’ll want to experience Bornholm’s most thrilling modern attraction at Opal Lake. This former granite mine turned crystal-blue lake offers Denmark’s longest zipline at 260-290 meters.

You’ll zip down from 47-48 meters high, reaching speeds of 70 km/h before splashing into the stunning waters below.

The “Tovbanen” operates summer months only, so plan accordingly. Rent neoprene pants and flip-flops for 219 DKK if you don’t have gear. Arrive an hour before closing to avoid crowds, and prepare for a 500-meter uphill walk to the starting point.

Beyond ziplining, you can cliff dive from 7-meter jumps, swim in pristine waters, or try rock climbing. The area attracts thousands of visitors annually who come for both the adrenaline rush and the breathtaking natural beauty.

The lake’s accessible by car with nearby parking.

Sample Smoked Fish in Gudhjem’s Harbor

Following your adrenaline rush at Opal Lake, head to Gudhjem’s picturesque harbor where the island’s most celebrated culinary tradition awaits. You’ll find Gudhjem Røgeri, a traditional smokehouse offering stunning Baltic Sea views alongside authentic smoked fish varieties like herring, salmon, and mackerel.

Don’t miss trying “Sol over Gudhjem”—smoked herring on rye bread topped with egg yolk, chives, and radish. It’s Bornholm’s signature dish. The fish buffet costs around 185 DKK and offers excellent value for sampling multiple varieties.

Since they don’t take reservations, arrive early during summer to snag outdoor seating overlooking the water. As the oldest smokehouse in Gudhjem harbor, this hotel represents generations of traditional smoking techniques passed down through time. You can also buy smoked fish from their retail shop as affordable souvenirs, bringing authentic Bornholm flavors home.

Climb Rytterknægten for Views Reaching Sweden

Since you’ve worked up an appetite from that delicious smoked fish, burn off those calories with a hike to Rytterknægten, Bornholm’s highest peak at 162 meters above sea level. Located in Almindingen forest near Aakirkeby, this free adventure offers spectacular panoramic views from its historic 22-meter granite tower.

Built in 1856 and enhanced with a steel extension in 1899, the tower provides stunning vistas across the island and, on clear days, views reaching Sweden across the Baltic Sea. You’ll spot the Ertholmene archipelago and surrounding forests from the 184-meter-high viewing platform. The name Rytterknægten translates to “knights squire,” reflecting the area’s historical connection to knighthood and equestrian activities.

The newly opened Trailcenter Rytterknægten (2025) features helpful amenities like bike repair areas and information points. Accessible year-round during daylight hours, it’s perfect for budget-conscious travelers seeking outdoor adventure.

The Sum Up

You don’t need deep pockets to fall in love with Bornholm. Most of these experiences won’t cost you much—hiking’s free, beaches don’t charge admission, and you can pack lunches for day trips. Book accommodations early if you’re visiting in summer, wear sturdy shoes for cliff walks, and don’t miss the local fish markets for budget-friendly meals. With just a few days, you’ll understand why locals never want to leave this Danish island gem.
