Visit Sønderborg & the island that looks like a dinosaur

Visit Sønderborg

Southern Jutland, with highlights like Ribe, Blåvand and the impossibly cute Møgeltønder, is swarming with Germans in the summer. In fact, just last week I heard that 90% (!) of the Danish summer houses on the West coast are rented by Germans.

Which to me is odd, because why aren’t Danes interested? Are we missing something here?

You guys know that I love a hidden gem, and I’m honestly so tired of hearing about the same tourist destinations in Denmark, like Copenhagen and Skagen, over and over again. Granted, Denmark is a small country, but we have so much stunning landscape and beautiful villages in all of Denmark, and I’m eager to explore new areas and share my findings with you. 

So, today I’ll introduce you to a little-known town in Southern Denmark and hopefully convince you to visit Sønderborg.

Where is Sønderborg?

Sønderborg is located on Als. A small island that looks suspiciously much like a dinosaur.

See what I mean? ↓

It even has those hilariously tiny arms like T-Rex 😀 


Als is just 35 km from the Danish-German border, which makes it closer to Hamburg than Copenhagen. As I’ve mentioned before, Southern Denmark is a culturally mixed area of Danes and Germans.

This means you’ll find German schools and Kindergardens in Sønderborg, and you will inevitably hear the charming greeting: “Mojn”, which is used in all of Southern Denmark and Northern Germany. 

10 things to do in Sønderborg

Sønderborg has a lot going on, so you won’t run out of things to do here. It’s also a great base for exploring the rest of Als and Southern Denmark. Let’s take a look at some of the best things to do in Sønderborg:

1. Sønderborg Castle 

The most popular sight in town is Sønderborg Castle. The castle was built in the 13th century and became one of the strongest Danish fortresses in the Middle Ages. It’s also known as a prison for King Christian II, who was lured into an ambush and held prisoner at Sønderborg Castle for 17 years (1532-154).

2. Enjoy a concert at Alsion

Another popular activity is to spend the night enjoying a concert, lecture, theatre or stand-up comedy at local concert hall, Alsion.

3. Island hop with one of the ferries

From Fynshav on Als, you can take the ferry to Funen or Ærø (very beautiful little island). The ferry named Ellen, sails from Als to Ærø 3-7 times a day and from Als to Funen every other hour in just 50 minutes. You can bring your car, but it costs extra.

4. Walk along the promenade

Sønderborg promenade offers a plethora of sights. Especially considering how small it is. Here are just a few of the interesting sights from the King Chr. X bridge to Sønderborg Castle:

  • Buy fresh fish every afternoon from Fru Jensen’s fishing boat 
  • A statue called “The Myth” representing the legend of King Christian’s Table
  • Ringrider track and monument – Sønderborg has the largest ringrider festival in Denmark and here’s a monument to honour that
  • A 2.3m high bronze sculpture called “Flounder in control” by 1999 Nobel Prize recipient in Literature, Gunter Grass. 
  • Watch the royal yacht Dannebrog during summer when the Queen visits her royal summer residence.
  • Sønderborg Castle (at the south end of the promenade)

5. Scandinavia’s largest collection of barrows

In Blomeskobbel forest, you’ll find Scandinavia’s largest collection of burial mounds and barrows from 3500 B.C. The huge cover stone on one of the grave chambers weighs around 20 ton. Spend a day exploring Blomeskobbel, Skelde Burial Mound, the relics in Nørreskoven and Baronens Høj (also a burial site).

6. Visit “Fluepapiret” beach

The most popular beach in Sønderborg is called “Fluepapiret” (English: the fly paper) because it’s so visited. The beach is 5 minutes walk from the town centre, near Sønderborg Castle.

7. A scenic flight over Sønderborg

View Sønderborg and the rest of Als from the air in a Cessna 172. There’s room for three passengers, and prices start at 395 DKK. They only offer this flight during summer (and sometimes not at all). I recommend emailing or calling Sønderborg airport and ask about availability.

8. Enjoy the day at Augustenborg Palace

Augustenborg Palace is one of Denmark’s most beautiful and historic castles. Explore the Rococo-style palace and garden, situated above the Augustenburger Fjord. The grounds includes a Baroque-style and a sculpture garden, which is home to 100 sculptures and is the second largest of its kind in Denmark.

9. Visit Frøslev prison camp (from WWII)

During World War II, the Frøslev Camp was built to avoid the deportation of Danish political prisoners to concentration camps in Germany. Several thousand Danes were imprisoned by Gestapo in the Frøslev Camp

Unlike the concentration camps, living conditions in Frøslev were bearable and there was sufficient food. The museum is less gruesome than the other Nazi concentration camps in Europe.

10. Relive history at Dybbøl Mølle

Dybbøl Mølle is a mill museum and national symbol of Danish bravery. It was the final battle field during the war in 1864, when Denmark lost the war against Preussen (Germany) and the country border was moved up north. Today, Dybbøl Mill and the surrounding buildings are a museum, were you can learn about Dybbøl as a memorial sight for both Danes and Germans.

Sønderjysk Kaffebord

And now on to the food!

If you like cake, there’s one thing you HAVE to try in Southern Denmark: ‘Sønderjysk Kaffebord’ – literally, a ‘Southern Jutland coffee table’. Danes love meeting up for coffee and cake, but here, they take it to the extreme. For birthdays or coffee time, you’ll be served seven types of soft cake and seven kinds of biscuits. 

My family is from Northern Jutland, where we have a similar tradition, so at family birthday parties there are always 7-10 different cakes to choose from. And then my mom likes to throw in some freshly cut fruits and buns with homebaked leverpostej and 5-6 other choices of fillings. Anything less just won’t do.

You can try Sønderjysk Kaffebord at a few castles or inns around Southern Denmark. Here are two nearby options, which you can conveniently combine with a trip to a traditional Danish castle:

The best restaurants in Sønderborg

Another thing you need to know about the regional cuisine in Southern Denmark is that it’s fusion cuisine. That means you’ll get the best of German & Danish food. Think sausages, smoked foods and a combination of sweet & sour. You can relish the regional delights at one of the many restaurants in Sønderborg. Here are a few of the best ones:

  • Huset Blom (traditional Danish food)
  • Restaurant Colosseum (try Prince Frederik’s favourite dish – the house specialty)
