Barnafoss is really more of a series of rapids as the Hvítá River (not to be confused with the river by the same name responsible for Gullfoss) is forced through a narrow rocky chute that once had a natural bridge spanning across it. Meaning "children falls", the bridge was destroyed at the request of the mother of the two children who fell off the bridge and drowned here while she (as well as the rest of her family except the kids) was attending Christmas mass in the nearby village. This waterfall is in the same area as Hraunfossar.
