Knudeklint and Hanklit are now UNESCO World Heritage Sites

Knudeklint on the island of Fur and Hanklit on the island of Mors – both in Limfjord region, Northern Jutland, have been inscribed on the UNESCO World Heritage List.

What makes Knudeklint and Hanklit truly exceptional is that they expose one of the world’s best-preserved sequences of moler—a rare marine diatomite deposited around 54 million years ago during the Early Eocene. Interbedded with more than 180 layers of volcanic ash from massive eruptions in what is now the North Atlantic, the cliffs provide an extraordinary geological archive of a time when Earth’s climate underwent dramatic change.

The area is also internationally renowned for its exceptionally well-preserved fossils. Fish, birds, insects, turtles, plants, and other organisms have been preserved in remarkable detail, offering scientists unique insights into ancient ecosystems and the evolution of life following the extinction of the dinosaurs. These discoveries have made Knudeklint and Hanklit key reference sites for geological and paleontological research worldwide.

Before the assembled delegates, it was affirmed that the two moler cliffs in the western Limfjord are of Outstanding Universal Value. Together, they preserve a unique record of Earth’s history and provide invaluable evidence of geological processes, climate change, and biodiversity from over 50 million years ago—heritage of global importance that must be protected for future generations.

With this inscription, Knudeklint and Hanklit join an exclusive group. This marks the tenth time UNESCO has inscribed Danish sites on the World Heritage List. Other Danish World Heritage Sites include:

  • The Jelling Monuments
  • Roskilde Cathedral
  • Kronborg Castle
  • Stevns Klint
  • The Wadden Sea

The two sites are easy to visit in a single day, though giving yourself two days allows time to enjoy the scenery, museums, and walking trails.

Knudeklint (Fur)

If you’re interested in geology, Fur is exceptional. The white moler cliffs contain volcanic ash layers and fossils dating back about 54 million years, making almost every hike as interesting scientifically as it is scenic. There are several hiking routes. The circular hiking route around the island is approximately 23 km long. Photo: Niels Lisborg.

Knudeklint is located on the northern coast of the island of Fur.

Getting there.

  • Drive to Fur via the ferry between Branden and Fur (the crossing takes about 4 minutes).
  • Free parking is available near the cliff.
  • From the parking area, it’s a short walk to the cliff edge and viewpoints.

What to expect.

  • Gentle walking trails with spectacular views across the Limfjord.
  • Exposed layers of moler and volcanic ash that are clearly visible.
  • Excellent opportunities for photography, especially in the morning and late afternoon.
  • Fossil collecting is only permitted in designated areas—please follow local regulations and avoid damaging the protected cliffs.

Hanklit (Mors).

Hanklit on the northern part of the island of Mors is Denmark’s largest moler cliff. Rising about 61 metres (200 ft) above the Limfjord, it should be explored with great care due to its steep drops and the risk of landslides.

Hanklit is located on the northern coast of the island of Mors.

Getting there.

  • Accessible by car from the mainland via the bridges to Mors.
  • Parking is available close to the site.
  • A well-maintained staircase and paths lead down toward the beach, where the impressive cliff face can be viewed up close.

What to expect.

  • A dramatic 60-meter-high cliff showing the distinctive alternating light moler and dark volcanic ash layers.
  • One of Denmark’s most iconic geological landscapes.
  • Great hiking opportunities along the coastline and cliff tops.

Suggested itinerary.

If you’re visiting both sites:

  1. Start at Hanklit in the morning.
  2. Visit the nearby Fur Museum, which houses one of the world’s finest collections of moler fossils and explains the geological history behind the UNESCO inscription.
  3. Take the short ferry to Fur.
  4. Spend the afternoon exploring Knudeklint and enjoy the panoramic views before sunset.

Visitor tips.

  • Wear sturdy shoes—the paths can be uneven and slippery after rain.
  • Bring a windproof jacket, as the cliffs are often exposed to strong coastal winds.
  • Allow 1–2 hours for each site, or longer if you enjoy hiking.
  • Stay on marked paths and respect barriers to help protect this newly designated UNESCO World Heritage Site.
  • The best light for photography is early morning at Hanklit and late afternoon or sunset at Knudeklint, though both are beautiful throughout the day.

Together, Knudeklint and Hanklit offer one of Northern Europe’s most remarkable geological experiences, where visitors can literally walk through a 54-million-year-old chapter of Earth’s history.
