Denmark’s largest artificial lake offers a peaceful escape into the countryside, with forest-lined shores, fishing opportunities and scenic walking trails. Created almost a century ago to generate hydroelectric power, Tange Lake has become a destination for outdoor enthusiasts exploring Denmark’s Jutland region.

Known locally as Tange Sø, the lake was formed in 1920 when the Gudenå River was dammed. Today, its tranquil waters and surrounding green landscapes offer visitors a chance to experience a quieter side of Denmark, away from its bustling cities.
Located between the towns of Ans and Bjerringbro, Tange Lake is within reach of Viborg and Silkeborg, where visitors can find accommodation while exploring the surrounding countryside.
According to Islands, the lake is particularly popular with anglers and hikers, offering a variety of ways to enjoy the outdoors throughout the year.
Fishing on Denmark’s largest artificial lake
Fishing is one of the main attractions at Tange Lake, where species include pike, perch, zander, roach, brown trout and eel.
Visitors can fish with the appropriate Danish fishing licence and must follow local regulations, including restrictions on fish sizes and designated closed areas during breeding seasons. Certain additional permits may also be required, depending on the circumstances.
For anglers hoping to catch pike, areas around headlands and reed-lined shores are worth exploring. Travellers planning to prepare their catch can consider staying at a campsite or self-catering accommodation nearby.

Hiking trails and lakeside adventures
Beyond fishing, Tange Lake provides opportunities to explore the Jutland countryside on foot. Trails wind through woodlands, green pastures and small settlements, with quiet spots along the way for picnics and scenic breaks.
During warmer weather, visitors can also enjoy swimming at designated areas around the lake. Tange Sø Marina in Ans is one option for those looking to spend time by the water.
Another way to experience the landscape is by taking a solar-powered boat trip, which operates seasonally from May to September. The journey offers views of the lake and surrounding countryside, as well as a chance to see the historic Tange hydroelectric power station.
Nearby, the Energimuseet offers an interactive introduction to electricity and energy production, adding an educational stop to an outdoor-focused itinerary.
A quieter side of Denmark
Tange Lake combines outdoor recreation with a glimpse into Denmark’s energy history. Whether spending the day fishing, following woodland trails or cruising across the water, visitors can enjoy a slower-paced escape in the heart of Jutland.
For travellers looking beyond Denmark’s best-known attractions, this man-made lake offers a different perspective on the country’s natural landscapes.
