Den Hvide Mær (The White Boulder) – Guldborgsund

A pale glacial boulder in the shallow waters of Guldborgsund, Den Hvide Mær quietly links ice-age geology, seamark history and tranquil coastal scenery.

4.5

Den Hvide Mær is a striking glacial boulder resting in shallow water on the Lolland side of Guldborgsund, south of Nykøbing Falster. About 2 m high and over 4 m long, this pale rock once served as a natural seamark for sailors and today draws paddlers, nature lovers and geology enthusiasts. Reached via a rural walk and shoreline access, it offers quiet views across the sound, framed by low fields, big skies and birdlife skimming the water’s surface.

Local tips

  • Wear sturdy, weather-appropriate footwear; the approach runs over rural ground and the coastal edge can be uneven or soft after rain.
  • Bring binoculars or a zoom lens to better appreciate the boulder’s details and the birdlife that often rests around it.
  • Plan your visit for calm or lightly windy weather; low waves and softer light make the stone’s pale colour and reflections stand out.
  • Combine the stop with a longer walk along the local coastline or a paddling trip on Guldborgsund for a fuller sense of the landscape.
  • There are no facilities directly by the shoreline, so bring water or snacks if you intend to spend more time in the area.

Getting There

  • Train and walking

    From Nykøbing Falster Station, travel is on foot from the town’s southern edge toward Priorskov and the coast. The total walking time is typically 45–60 minutes each way over mostly flat roads and farm tracks, with no dedicated footpath for part of the route. There is no separate transport fare beyond your train ticket to Nykøbing, and the walk is straightforward but not ideal for wheelchairs or prams due to uneven rural surfaces.

  • Bicycle from Nykøbing Falster

    Cycling from central Nykøbing Falster to the Priorskov area and onward to the coastal approach usually takes 20–30 minutes each way, depending on pace. The route combines local roads and minor lanes with generally light traffic, but there are no marked cycle paths throughout. Renting a bike in town typically costs around 80–150 DKK per day. This option suits visitors comfortable riding in mixed traffic and on occasional gravel or dirt sections.

  • Car and short walk

    Reaching the Priorskov area by car from central Nykøbing Falster takes about 10–15 minutes via local roads. There is no formal car park for the boulder itself, so you need to leave the vehicle in a suitable legal spot nearby and continue on foot across rural terrain for approximately 15–20 minutes. Expect standard Danish fuel and running costs only; there are no dedicated parking fees specifically for Den Hvide Mær.

  • Kayak or canoe on Guldborgsund

    Experienced paddlers exploring Guldborgsund by kayak or canoe can include Den Hvide Mær as a waypoint. Depending on the chosen put-in along the nearby coast, reaching the boulder generally takes 30–90 minutes of paddling each way in calm conditions. Local kayak rental in the region is commonly in the range of 300–500 DKK per day. Trips are weather-dependent, and suitable clothing, buoyancy aids and basic coastal paddling skills are important.

A pale giant in the shallow waters of Guldborgsund

Den Hvide Mær is an ice-age boulder lying in the shallow waters between Lolland and Falster, just off the gently sloping shoreline south of Nykøbing Falster. Pushed here by glaciers thousands of years ago, the stone ended its journey in Guldborgsund and now sits partly submerged, about 83 metres from the coast. Its pale, almost chalky appearance stands out clearly against the dark water, especially in low, slanting light. The boulder measures roughly 2 metres in height and around 4.5 metres in length, making it one of the more prominent stones in this stretch of the sound. On calm days its rounded back mirrors in the water, while at higher water levels it appears lower and more secretive, as if hiding in the waves. From the nearby fields and shoreline you enjoy wide, open views across the sund and can sense how exposed this stone has been to wind, ice and saltwater for millennia.

From navigation mark to named landmark

Long before charts, buoys and electronic navigation, Den Hvide Mær served a very practical purpose. Its bright colour and fixed position made it a useful point of reference for seafarers moving through the narrow waters of Guldborgsund. Coastal sailors learned to recognise its pale shape and used it as a natural seamark when passing between the two islands. The name “Den Hvide Mær” literally means “the white mark”, a reminder of this maritime role. Standing on the shore and looking out, it is easy to imagine low, traditional boats slipping past in the half-light, their skippers gauging distance and depth from this solitary stone. Today, modern markers have taken over, yet the boulder still feels like part of an older navigation system, quietly tying together land, sea and local memory.

Geological story written in stone

Geologically, Den Hvide Mær is a classic glacial erratic: a large block transported by moving ice from its original bedrock and deposited far from home as the ice sheet melted. Its size and rounded forms tell of grinding travel within the glacier, while its pale tone hints at a different origin than the surrounding sediments and clays. Along this coast, the low landscape, fertile fields and shallow banks all bear traces of the last ice age. Visiting the boulder makes these slow processes tangible. The stone invites close observation of its crystals, surface cracks and lichen patches, each a clue to its long exposure. For those interested in geology, it offers a compact, easily understood example of how ice has shaped Lolland-Falster’s coasts.

Quiet waterside atmosphere and wildlife

The setting is remarkably peaceful. You approach through open farmland where the wind moves over crops and reeds, and the sound of traffic quickly fades. Closer to the shore, the landscape shifts to grassy edges, low banks and shallow water dotted with stones and seaweed. The boulder itself is often accompanied by gulls, waders and occasional ducks resting nearby. Across Guldborgsund you can trace the opposite shoreline and, on clear days, follow the curve of the coast far into the distance. The mood changes with the weather: in sunshine, the stone gleams softly and the water sparkles; under grey skies, both sea and rock take on cooler tones and a more introspective feel. It is an easy place to linger, simply watching light move over water and listening to wind and bird calls.

Simple pleasures for walkers and paddlers

For visitors on foot, the main experience is the view from land. The boulder lies far enough offshore that you stay on the shoreline, observing its profile without needing to wade. The rural walk in and out is part of the charm, adding a sense of discovery as fields give way to the low coastal edge. Paddlers in kayaks or canoes on this part of Guldborgsund often use Den Hvide Mær as a visual waypoint on their route. From the water, the stone appears larger and more sculptural, and you can appreciate how neatly it sits on the shallow seabed. Whether viewed from land or sea, it offers a small but distinctive highlight on any slow exploration of Lolland-Falster’s quiet inner waters.

A modest but memorable coastal stop

Den Hvide Mær is not a developed attraction with facilities and signage; its appeal lies in its simplicity. A single pale stone, an open horizon, and a shoreline shaped by ice and time together create a modest but memorable stop. It works well as a short detour on a day of exploring Nykøbing Falster and the surrounding countryside, or as a contemplative pause during a longer coastal walk. For anyone interested in geology, coastal landscapes or the old relationship between seamarks and seafaring, this unobtrusive boulder offers a surprisingly rich story. The experience is unhurried and low-key, and that is precisely what makes it special.
