Gluggafoss, also known as Merkjárfoss, is a two-tiered waterfall located on the Merkjá River in the Southern Region. The Merkjá River has many beautiful waterfalls, but Gluggafoss is the most significant. Gluggafoss is increasing in popularity, but it is still a relatively overlooked 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.

Granni, “neighbor,” is the direct sibling of the more popular Háifoss. Granni is ranked the 7th tallest waterfall in Iceland, measuring at a total of 417 ft.
