Rolling hills shaped by the ice age rise to 137 meters in this Danish landscape, where sand lizards bask on slopes and wild horses maintain open grasslands near ancient castle ruins.
Mols Bjerge National Park covers 180 square kilometers of Denmark's Djursland peninsula. The ice age left behind rolling hills that rise to 137 meters, where you can now spot rare sand lizards sunbathing on the slopes. Walk through the ruins of Kalø Castle on its island, climb the 49-meter Jernhatten cliff for views of the Kattegat sea, or explore the glacial valleys where wild horses maintain the open grasslands.
Getting to Mols Bjerge
Drive 35-45 minutes east from Aarhus to reach Rønde, the main entrance point to the park. Bus 123 connects Aarhus to Rønde with a 45-minute journey. Look for the brown national park signs directing you to multiple parking areas near trails and viewpoints.
Walking the Ice Age Landscape
The 21-kilometer Mountain Route crosses the park's glacial hills on narrow dirt paths. This internationally certified trail passes grazing animals and small forest sections. For easier walks, take the 5-kilometer Toggerbostien or the 3.5-kilometer Italian Trail, both with gentle slopes and clear markings.
Wildlife and Natural Areas
The park contains more than 50% of Denmark's documented wild plant species. Look for sand lizards basking on south-facing slopes and rare butterflies in the grasslands. The bird tower at Stubbe Sø lake overlooks a common nesting area for waterfowl. Wild horses, cattle, and sheep graze throughout the park, maintaining the open grasslands and preventing forest growth.
Historical Sites and Viewpoints
Walk the 500-meter medieval cobblestone causeway to reach Kalø Castle ruins on its small island. Climb Jernhatten cliff, locally known as the Iron Hat, for clear views across the Kattegat sea and surrounding hills. You'll find Bronze Age burial mounds at Tustrup and Denmark's largest preserved stone dolmen at Poskær Stenhus.
Visitor Center and Activities
Find maps, information, and guided tour bookings at the visitor center in Nedre Strandkær, a restored 1730s building. The center organizes kayaking courses and provides maps for amber hunting along the coast. Scientists use the facility for research, and it doubles as a training center for nature guides.
When to Visit
The park stays open year-round. Summer temperatures range from 20-25°C with more visitors on trails. Spring and fall bring temperatures between 10-15°C with fewer people. Winter activities are limited, with some trails becoming muddy. Check the visitor center website for seasonal opening hours.
