The Iddefjord

The Iddefjord runs along the Swedish border from the Singlefjord and the idyllic Hvaler islands to the village of Berby in the Enningdal valley. The outermost stretch is called the Ringdalsfjord, but it becomes Iddefjord from the point where it makes a sharp bend.
The fjord is home to an abundant variety of fish species, and bathing is a popular activity in the summer. The part of the fjord that runs along the border to Halden has been called eastern Norway's only west coast fjord. It is narrow and idyllic with unexpected and steep natural formations on both sides.
If you sail up the middle of the fjord, you have the national boundary right under your keel. To star-board is Sweden and to port is Norway!
The Iddefjord has also witnessed the clamour of historical events. In times of war, strong fortifications were built at the steep sides of the fjord.
Remains of these fortifications can still be seen today. The border fjord has also been the scene of substantial naval battles between Norwegians and Swedes.
