Hraunfossar

Hraunfossar is a series of waterfalls in Borgarbyggð where countless water streams emerge from the porous Hallmundarhraun lava field and flow approximately 900 meters across dark volcanic rocks. These flows eventually merge into the Hvítá River, creating a striking water landscape.

The Hallmundarhraun lava field formed roughly 1200 years ago from a volcanic eruption beneath Langjökull glacier, creating the foundation for this waterfall system. This eruption created the porous rock structure that allows water to emerge today.

The name comes from two Icelandic words: 'hraun' meaning lava and 'fossar' meaning waterfalls, a direct description of what you see here today.

The site is accessible via wooden walkways that let visitors view the different water streams up close from multiple angles. The paths are well-maintained, and the water flow remains steady regardless of season, making it a reliable destination any time of year.

Rather than falling from a single high cliff like typical waterfalls, the water here emerges through countless small springs scattered across the porous lava rock. This diffuse water system creates a rare natural display you won't find in most other places.
