Urriðafoss is Iceland’s largest waterfall in volume, with a high river drop rate of 12,700 cfs (360 cms). The waterfall is located on the Þjórsá, the longest river in Iceland. In Icelandic, Urriðafoss translates to “Trout Waterfall.” The Þjórsá is a famous river for salmon and trout fishing. Even seals are reported to travel up the river to Urriðafoss to catch salmon.

Brúarárfoss, also known as Brúarfoss, is titled “Iceland’s Bluest Waterfall.” It’s a small waterfall at only around 10 ft (3 m) in height, but it’s known for its horseshoe-like shape and vivid blue water. The glacial river Brúará creates the waterfall and is sourced from the Langjökull glacier. The bright blue waters are only exacerbated as Brúarárfoss plunges into the crevice that it creates within the dark volcanic rock.
