Mjels can be explored through nature watching, trails and local history. At Mjels Sø, the restored landscape and birdlife are among the defining features. There are also hiking and cycling routes, historical traces at Mjels Vig and the architectural history of Mjelsgård. When planning, it is worth distinguishing between the different types of routes and activities.

Mjels Sø: Nature and Birdlife

Mjels Sø was restored in 2005 and is considered an example of restored nature. It covers 45 hectares and is up to four metres deep. A canal and sluice gates connect it to Mjels Vig. These measurements and the water connection offer different points of reference for understanding the lake in its landscape.

Among other birds, ducks, moorhens and geese can be seen at the lake. There is also a good chance of seeing a white-tailed eagle hunting for food. In addition to the named bird species, those interested in nature watching therefore also have the opportunity to spot a white-tailed eagle here.

Distinguishing Hiking Trails by Route Type

The hiking route at Mjels Sø is 4.5 kilometres long for the round trip and runs through easy, flat terrain. This distance covers both legs of the route combined. Trail conditions may change; check the current situation before setting out.

The Alsstien is 12.6 kilometres long and runs between the ferry terminal in Hardeshøj and Nordborg Castle. It passes through Mjels Mark and by Mjels Vig and Mjels Sø. The route is unmarked. The 12.6 kilometres describe a route between two endpoints, whereas the 4.5 kilometres at the lake cover the round trip. These different distances help you choose the hiking option that best suits your plans.

There is a car park for the Alsstien at Mjels Sø, by the old yellow pump house. The pump house has been preserved. This gives you a clear landmark for the route as well as a visible architectural feature by the lake.

Cycling and the E' Govl Coastal Path

A cycling route runs from Oldenor via Mjelsvig and Æ Gavl to Mjels, where it meets the route again at the marina. It is considered challenging and especially scenic. As trail conditions may change, it is advisable to check the current situation before your ride.

E' Govl is a stretch of coastline that connects Oldenor with Mjels Sø and runs along the coast by Mjels Vig. The path there is very narrow and follows a hillside; cycling on this section is not recommended. Keep this specific restriction in mind when planning your routes in the area.

Mjelsgård and Traces of the Viking Age

Mjelsgård is one of Denmark’s oldest known manor houses; its origins date back to 1245. The building was bombed in 1942 and later rebuilt. Its origins, bombing and reconstruction mark distinct stages in its history and make the building’s passage through time tangible.

Mjels Vig also has an archaeological connection: place names, burial finds and loose finds show that the bay was visited during the Viking Age. Along with the architectural history of Mjelsgård, this offers a second perspective on the area’s past, extending beyond a single building.

Fishing and Accommodation

Mjels Sø is home to pike and a population of perch, making the lake of interest to anglers. Fish stocks and fishing conditions may change. Membership of Sportsfiskerforeningen Nordborg is required to fish. The exception is school pupils with a specially issued school fishing permit. Check the current regulations before fishing.

For an outdoor overnight stay, there is the private Mjelsvig Hø-teltplads campsite, with two shelters. It can be booked in connection with hikes on the Alsstien or kayaking trips. Booking conditions may change; check the latest information if you include this option in your plans.
