The Hotel 6400, Sure Hotel Collection by Best Western is located near the edge of Sonderborg and thus close to forest and beach. Still, there are only approximately two kilometers to the vibrant urban life in Sonderborg with the old royal castle Sonderborg Castle, where Christian II was a prisoner in the 16th century, and which today houses an exciting museum about Southern Jutland’s changeable history. Hotel 6400 in Sonderborg is all in all an excellent base for guests who want to experience Southern Jutland’s many experiences and get acquainted with the area's special culture and history. You can visit Dybbol Mill and the history center, which tells about the war in 1864, and you can take a walk on the 74 kilometers long Gendarmsti along the current Danish-German border from Padborg to Horuphav on Als. You can also visit the royal family's summer residence Grasten Castle and enjoy the floral splendor in the beautiful castle garden. A special South Jutland tradition that dates to the Middle Ages is ring riding, which takes place every summer in Sonderborg, Grasten and Aabenraa. If you want to shop south of the border, it is less than 50 kilometers from Flensburg.
