Oksbøl Forest has many routes of varying lengths. The red route takes you around the many bogs in the forest.

Alsstien: Hardeshøj - Nordborg Castle

Cycling and hiking route, 13 km.

The trip goes from the ferry port in Hardeshøj through Mjels Mark to the narrow, beautiful entrance to Dyvig at Steg Gab. The trip then continues along Mjels Vig at Røde Næb and along E Gaul to Nordborg.

The landscape varies between beautiful views of the coves and passages through dense hedges and the tunnel valley Gammeldam. Along Oldenor there are good opportunities for bird watching. The terrain is hilly, so be prepared for a walk that may make you sweat.

The stag jump boat in Holm

The Hjortspringbåden is a copy of the original Hjortspringbåden, which dates from around 350 BC. The Hjortspringbåden is 19 m. long and built to match the original construction.
The boat was found in Hjortspring Mose in 1921, and was part of a large weapon offering in the bog. The original is on display at the National Museum. The boat is the oldest plank-built boat in the Nordic countries. 140 volunteers are behind the boat building.

Mjels Pumpehus - the center of the nature park

Enjoy the beautiful view and birdlife from the old pump house at Mjels Sø. Several hiking trails depart from the Pump House. The house serves as an information and packed lunch place with a viewing platform. There is a toilet nearby.
Mjels Pumpehus and the drainage canals at Mjels sø and Bundsø are today witnesses to the 1800th century drying up and draining of the lakes. The lakes were recreated in 1993-2016. Today, the lakes appear as they did at the end of the 1500th century, when they were cut off from the sea.

Nordborg Castle

Around the year 1150, the first castle was built on Als. Surrounded by a moat, Alsborg was well protected on the south side of Nordborg Lake. The castle has burned down twice and the current buildings were built during German rule in 1910. Today, Nordborg Castle forms the setting for the Scienceefterskolen Nordborg Slot.
The castle park is open to the public.

Jollmand's farm

In the village of Holm lies the Alsian hook farm from the 1700th century, Jollmands Gaard. The farm is very well preserved and contains a fine exhibition of everyday life in the countryside at that time. The buildings are shaped like a hook and are a beautiful example of Alsian half-timbering.

Havnbjerg Mill

The beautiful thatched windmill from 1835 is located high on a hilltop above Havnbjerg and with Havnbjerg Church as a neighbor. The mill was in operation until 1961.
