Coast and nature on Bornholm

Natural gems with deep roots

Bornholm’s nature begins in the bedrock. The island is the only place in Denmark where the bedrock emerges in the landscape, giving the coast and nature a particular weight. Here, granite rises vertically from the sea, cracks open like green valleys, and water finds its way down the rock walls after rain and thaw, especially in spring when snow and ice melt.

You sense it clearly in the rift valleys. In Ekkodalen, the cliffs stand dark and steep among the trees, and in Døndalen you can hear the waterfall before you see it. Especially in winter and spring, the water gains more force and movement through the landscape.

Elsewhere, history lies heavy and quiet. In Paradisbakkerne and by the island’s rocking stones, you meet the great boulders the ice once left behind. They look immovable, but some of them can be shifted if you find exactly the right point.

When the day lets go, Bornholm shows another side. Far from the lights of the towns, the night sky can feel unusually clear, especially along the coast. Here, nature grows quiet in a new way, and your gaze lifts from cliffs, forest floor and sea to the stars above the Baltic.

Where nature has taken over

Some of Bornholm’s special natural areas were shaped by people before nature slowly took them back. Old quarries, raw rock edges and landscapes marked by coal and industry tell another side of the island’s history.

At Opalsøen, the former granite quarry has become a deep, clear lake between steep cliffs. At Kultippen, the dark, almost moonlike landscape remains as a trace of coal mining by the coast. Here, traces of human work meet nature’s slow transformation.

Here, history becomes visible in the landscape. You can walk through the traces of what people have broken, dug and moved, and see how wind, water, plants and time slowly give the places a new form.

White sandy beaches and gentle waves

You find the contrast to the cliffs in the south, where the coast opens in long, bright stretches. At Dueodde, the beach becomes wide, the sky larger and the water shallow enough for the day to drift quietly by with swimming, bare feet and children at the water’s edge.

The sand here is something special. It is so fine that it almost sings beneath your feet when it is dry, and it is said that sand from Dueodde was once used in hourglasses. Here, Bornholm’s coast and nature feel lighter and softer, yet the sea is still close.

Around the island, the beaches change character. Some are wide and family-friendly, with plenty of room for towels, beach bags and long days by the water.

Others are small and more hidden, tucked between cliffs, harbours and coastal paths. Here you can sit on a sun-warmed rock and slip straight into the clear, deep water.

On Bornholm, the beach is not only a place to swim. It is a place to walk, collect stones, feel the wind and watch the light shift over the Baltic Sea. From the white sandy beaches to the south to the small rocky coves to the north and east, the sea follows you all the way around the island.

Forests, lakes and wild European bison

Move away from the coast and into the heart of the island, and you come to Almindingen. Here, the forest stands close around lakes, bogs, paths and rift valleys, and the landscape has a different calm than out by the sea.

At Rytterknægten, Bornholm reaches its highest point. Here, Kongemindet stands among the trees, and from the tower you can look out across the crowns of the forest and further over the island.

The forest also holds quiet sheets of water, damp hollows and old traces in the landscape. Here you can walk through forest floor, rock and thicket while the light shifts between the trunks.

In Bisonskoven, European bison live in a large enclosure. The heavy animals move through the forest and help create clearings and variation on the forest floor. If you meet them on your walk, stay on roads and paths, move calmly and keep a good distance.

Seeing a European bison among the trees is an intense encounter with nature. The large animals give the forest a very special presence, and the encounter is best experienced calmly and from a distance.

Birdlife, bogs and rocky islands

Bornholm’s coast and nature can also be found in the quiet wetlands, in the sounds of the reed beds and on the small rocky islands out in the Baltic Sea, where the birdlife takes on a completely different scale.

In Almindingen, Bastemose is a quiet stop between forest and wetland. From the birdwatching tower you can look out across the bog and follow the life between reeds, water surfaces and the forest edge. You may be lucky enough to see cranes, bitterns and birds of prey over the landscape.

At Ølene, nature opens into a larger bird reserve with bog, meadows and reed beds. Here you experience the landscape from the towers at the edge of the reserve, where you can stand still with binoculars and let the landscape come to you.

And then there are Ertholmene. A boat trip from Gudhjem takes you out to the small rocky islands northeast of Bornholm, where the sea, history and birds all fill the space at once. Large colonies of seabirds breed on Græsholm, and razorbills and guillemots have one of their most important Danish breeding sites here. The island itself is a closed bird reserve, but the birdlife is a clear part of the experience when you visit Christiansø and Frederiksø.

Life in the air changes with the season. Migratory birds, sounds from the reed beds, a lone bird over the bog or seabirds above the cliffs give each place its own atmosphere.

When nature calls for movement

The coastal paths, forests, cliffs and sea invite you to get out and experience Bornholm actively. Here you can hike, cycle, climb, paddle and dive while the landscape constantly changes around you.

In some places, the terrain is open and easy to navigate; elsewhere it is steep, rugged and more demanding. That is part of the experience and one of the reasons why Bornholm is so well suited to active outdoor experiences.

An active starting point in the forest

In the middle of Almindingen, close to Rytterknægten, is Trailcenter Bornholm. Here you can sit down with a picnic, take a break among the trees or use the site as a starting point for a trip further into the forest.

From the trail centre, routes spread out into the hilly terrain. Some follow forest paths, while the mountain bike trails in several places run directly over Bornholm’s bedrock. So you can come in hiking boots, hop on your bike or simply stay a little longer at the trail centre before continuing.

On the water and below the surface

When the path ends at the sea, the experience can continue on the water. Along Bornholm’s coast, you can paddle a kayak past the steep cliffs, stand on a SUP board in calm water or feel the wind take hold of sails and surfboard.

Below the surface, cliffs, seaweed, stones and small creatures await, whether you snorkel close to the beach or dive further out with a guide and equipment.

The sea around Bornholm can be gentle one day and more demanding the next. Always check wind, weather and local conditions before you go on the water, so you can choose a trip that suits the conditions.

Fishing along four coasts

Along Bornholm’s coast, the fishing changes with the landscape. To the north and west, the cliffs stand close to deep water. To the south and east, the coast becomes softer, with reefs, sandy bottom and shallower water. That makes the island exciting for anglers, whether the trip is about sea trout, garfish or simply a quiet moment by the water.

For many, fishing is as much about the place as the catch. About standing by the coast early in the morning as the light rises over the Baltic Sea. About reading the wind, the water and the stones beneath your feet. And about staying long enough for the rest of the day to fade a little into the background.

There are also options for calmer fishing trips at lakes and put and take waters, where children and beginners can join in. Wherever you fish, it is important to check fishing licences, protected areas and local rules before you cast your line.

Rock climbing on Bornholm

If you want to get close to Bornholm’s raw nature, you can take on the cliffs. Here, you feel the granite beneath your hands and experience the height above the sea in a completely different way.

Bornholm offers special opportunities for climbing in Denmark, both in old quarries and on selected rock faces. In some places, beginners can join guided tours, while more experienced climbers can find routes with greater challenges.

Climbing requires the right equipment, experience and respect for nature. Always check where climbing is allowed and follow local rules and recommendations before you begin.
