Opposite these islands, a large tongue of land invites you to take a walk. From here you have the best and quietest view of both islands. The headland is even mapped.☝️

June 4, 2024,Rund um Jütland 19: Sønderborg - Flensburg (Østersøruten)

Last stage, the air was out - and in more ways than one. After not even 10 km, a tire was flat again, the sixth breakdown in total (three each). Must be due to the terrible Danish gravel paths, each time a nasty sharp little stone was the culprit.

Our final stage takes us out of Sonderborg to the Dybbøl Mill and then along the Flensburg Fjord to Flensburg. We first have to get used to the many people again. It was beautiful, we had the North Sea and the Baltic Sea, sun, rain, storms but above all a lot of fun and lots of memories and impressions. Collection …

August 14, 2022,Flensburger Förde Tour von Flensburg nach Sønderburg - Nord

This tour is incredibly fun when done on an e-bike. It is quite demanding in some places, but always offers great views of the Baltic Sea.
Gravenstein Castle / Gråsten Castle is a worthwhile destination that is worth a detour. The new Kitchen Garden in particular is a highlight and also offers a small but fine café.

After worrying yesterday that our tour wasn't being recorded by Komoot, it suddenly appeared this morning. Strange 🤷
The photos aren't quite in the order they should be, but that's not a big deal.

It was beautiful; Sonderborg is always worth a visit. Lovely cafés, bistros, and restaurants by the harbor and in the city center, a great promenade along …

From Flensburg to Sønderborg – a bike trip through the fjord, the border and fairytale landscapes. Along the way, you will be delighted not only by the views of the water, but also by the picturesque Danish houses – low, colourful, with red roofs and gardens like from a postcard. The route is full of space and northern climate. However, …

June 1, 2024,Flensburg - Sonderborg - Flensburg

Inspired by @Silke W., today we went to our neighbors in Denmark, specifically to Sonderborg. First we took the train to Flensburg. From the station we went via Wasserleben, the Schusterkate border crossing and Kollund on the Baltic Sea coast cycle path more or less close to the fjord to Sonderborg. The small town on the fjord really surprised us. …
