Foss á Síðu is a commonly seen waterfall that is frequently passed. This waterfall is located in the Southern Region and is viewable from the Ring Road (Route 1). Foss á Síðu is not a mighty waterfall, but its slender cascade against the dark cliffside and vivid greenery makes it truly beautiful. Many would be surprised to learn that Foss á Síðu is Iceland’s 14th tallest waterfall.

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.
