According to legend, an ogress lives in the waterfall Háifoss. One day, a teenage boy traveling with his companions threw a rock into the river. That night the ogress, angered that the boy had scared away the fish on which she lived, went to the spot where the travelers were sleeping and tried to pull the boy away by his legs. His companions held him fast by the upper part of his body. After a lot of tussle the ogress relented and went away, but the boy was bedridden for a month after this.
