Augustenborg is a small palace town at the head of Als Fjord on the island of Als, suiting quiet stays with a fireplace. Billund Airport is a long drive away, so arrival is the main trade-off.
Augustenborg grew around its palace, begun in the years after 1651 by Ernest Günther and named after his wife Auguste. Around 3,100 people live here, at the head of Als Fjord with the Little Belt to the east. The palace buildings are closed to visitors apart from the palace church, which has special opening hours, and a small museum by the bell tower covers the ducal family. In the park, the remains of a linden tree once shaded H. C. Andersen. Als is a fertile island, once known for its fruit orchards. Nearly all homes have a fireplace, and none has a pool.
The capital of Als, with a good harbour and two bridges over Als Strait to the mainland side.
The former municipality is home to Danfoss, and Lake Nordborg and the Northern Forest lie on the east coast of the island.
Ferries run from here to Bøjden on Funen and to Søby on Ærø.
Billund Airport to Sønderborg is about 1 hour 29 minutes by car, and Augustenborg is on the same island. Ferries from nearby Fynshav run to Funen. Bus and train from Billund take far longer, so hire a car.
Only in part. The palace buildings are not open to the public, but the palace church opens at special times when no services are held, and a small museum by the bell tower covers the ducal family.
It sits at the head of Als Fjord, with the Little Belt to the east. Check each home's distance to the water, as Augustenborg itself is a town of about 3,100 people.
Yes, from nearby Fynshav. Boats run to Bøjden on Funen and to Søby on the island of Ærø, which gives a way onto the Funen side without driving round.
Augustenborg is the smaller, palace-centred town. Sønderborg is the island's capital, with a good harbour and two bridges across Als Strait, and is the better choice if you want a bigger town.
