"The Iddefjord (a classic fjord with a narrow watercourse and steep natural formations on both sides) runs along the Norwegian \u2013 Swedish border from the Singlefjord. The Iddefjord separates the Swedish province of Bohusl\u00E4n in the county of V\u00E4stra G\u00F6taland from the Norwegian municipality of Halden in the county of \u00D8stfold. It opens to the Skagerrak via the Svinesund and Hvaler archipelago (a cluster of classic skerries)."@en .
