Getting There

  • Walking

    From central Læsø, the route to Rønnerne guides you across open farmland and into the nature preserve’s distinctive meadow landscape. After leaving the bustle of Byrum, you’ll soon spot sweeping vistas of grassland and pools on the horizon. It’s about a 45–60-minute walk, offering a gradual immersion in the island’s rural tranquility. Expect a well-trodden path with just gentle undulations, and note that certain sections can become muddy after a rainfall.

  • Bicycle

    Cycling from Læsø’s central village takes most visitors through quiet country lanes, past grazing livestock and the iconic salt huts dotting the edge of the preserve. The journey usually takes 20–30 minutes. Bicycles can be rented in Byrum for around 80–100 DKK per day, and there are sturdy bike racks near the main access points.

  • Car

    Driving from the island’s center, you’ll pass through diminutive villages and reach the small parking areas bordering Rønnerne’s protected zone in around 15 minutes. Parking is free, but availability is limited especially during summer weekends. The last approach offers great views over the meadows and salt huts. Note that vehicles are not allowed beyond the marked lots; the rest of the reserve must be explored on foot.

  • Taxi

    A taxi from Byrum or Læsø’s ferry terminal can deliver you to the main entrance to Rønnerne in 10–15 minutes. Fares typically range between 120 and 170 DKK depending on the pick-up point. This is a convenient choice for those with limited mobility or traveling outside regular bus hours.

Discover more about Rønnerne

Stretching across the southern expanse of Læsø, Rønnerne is one of Denmark’s most remarkable nature preserves. Known collectively as 'The Rønner,' these salt meadows form a unique ecosystem shaped by centuries of tidal movement, salt production, and human history. The area covers more than 2,500 hectares and includes wetlands, peat bogs, and salt marshes—an endless mosaic of open sky, glistening pools, and wild grass. Birds flock to the area in astonishing numbers, with spring and autumn bringing thousands of migrating waders and geese. Rare species such as the avocet, curlew, and marsh harrier regularly nest or pass through, making Rønnerne a paradise for birdwatchers and nature enthusiasts alike. Historically, the area is also closely linked to Læsø’s renowned salt production, a tradition rooted in the Middle Ages. Evidence of old salt huts and recreated saltworks reveal how locals harnessed the briny ground water to produce Læsø salt—a process revived today as an immersive cultural experience. Cattle and sheep roam freely, their presence reminiscent of Læsø’s traditional low-impact agriculture which continues to help shape the landscape. Wandering Rønnerne offers a sensory feast: the sweet-salty tang of the air, the crunch of seashells beneath your boots, and the calls of snipe and plover echoing across the open meadows. Several information posts dot the region, providing insight into the fragile ecology and the enduring relationship between island life and the elements. In the height of summer, wildflowers burst into bloom, painting the grasslands with vibrant splashes of color. While Rønnerne can feel wild and remote, its gentle terrain suits both family outings and seasoned hikers looking for solitude amid Læsø’s salty wilderness.
