A fjord is a long, narrow inlet of the sea flanked by steep cliffs or mountains, carved by glacial erosion during successive ice ages. As glaciers retreated, they left U-shaped valleys that flooded with seawater, creating these dramatic coastal landscapes.
While Norway is synonymous with fjords, several European countries boast these geological wonders:
The undisputed fjord capital. The Geirangerfjord and Sognefjord (the longest and deepest at 205 km and 1,308 m) are UNESCO World Heritage sites. Others like Nærøyfjord, Hardangerfjord, and Lysefjord (home to Preikestolen) offer iconic scenery.
Iceland's fjords are younger and often still shaped by volcanic activity. The Westfjords region contains spectacular examples like Dynjandi waterfall cascading into Arnarfjörður. Note: Eyjafjallajökull is a volcano, not a fjord; Skaftafell is a nature reserve.
Scottish "fjords" are technically sea lochs—glacially carved inlets like Loch Fyne (the longest) and Loch Duich (with Eilean Donan Castle). They share the same glacial origin as Norwegian fjords.
Ireland has fjord-like inlets such as Killary Harbour. Greenland (geographically North America, politically European) features vast fjord systems like Scoresby Sound. The Faroe Islands offer dramatic, cliff-lined fjords like Sørvágsfjørður.
