Hofsa is one of the “big” northeast rivers and one of the two major Vopnafjordur rivers, the other being Sela. Hofsa has different characteristics to Sela. It has a long canyon on the top beats, a dramatic impassable falls and a string of challenging pools as the river thunders down the canyon. But once the canyon ends, the river turns into an almost endless string of long slow flowing pools, each one seeming more enticing and inviting than the last one!
