Overview
About Barnafoss
The river in the narrow channel
At Barnafoss, Hvítá is concentrated into a main channel through the rock. From the footbridge, the meeting of older and younger rock layers is visible beside the rushing water. The river's appearance changes with rainfall and temperature: at times it approaches the clarity of spring water, while at others it carries the appearance of a glacial river. Downstream, Hraunfossar are spring-fed cascades emerging beneath the lava field into Hvítá.
A channel shaped by erosion
The rock passage has changed over time. The Saga Geopark application describes erosion of the lava in the canyon and the waterfall's gradual retreat upstream. It also records a local account, handed down between generations, that the fall once lay a little farther downstream beside a different stone bridge. This combination of an observed erosional process and remembered landscape change helps explain why an old description of an arch need not match the feature visible today.
The children and the stone bridge
Barnafoss means Children's Falls. In the local legend retold by Visit West Iceland, two children at Hraunsás are left at home while their parents attend Christmas Mass. On returning, the adults discover that they are missing. Footprints lead to a natural stone arch across the river, where the trail ends. Their mother believes that they have fallen into the water and orders the arch destroyed to prevent another such loss. Some tellings bring a curse into the bridge's destruction. These are variants of a place-name legend; the account does not establish the children's deaths as a documented historical event.
Names and built crossings
The regional destination authority also records Bjarnafoss as an earlier name and dates the first constructed bridge over the falls to 1891. That bridge belongs to the history of transport across Hvítá. It should be distinguished from the natural stone arch of the legend: a built crossing and a rock formation tell different parts of the site's history.
Protection and access
Barnafoss and Hraunfossar were protected together as a natural monument in 1987. The Nature Conservation Agency describes marked paths, defined viewpoints and wheelchair access on part of the site. Protection extends to vegetation, wildlife and geological formations. Visitors should use the designated routes and leave the rocks and plants undisturbed; the agency prohibits off-road driving and damage to the site's natural features.
