Tips from the Community

August 18, 2025, Álafoss

Álafoss is a waterfall on the Varmá River in Mosfellsbær in the capital region of Iceland. In 1896, a hydroelectric wool factory was named after this waterfall. Today, only a wool and knitwear shop remains here. Since April 2013,[1] the waterfall and its small 14,000 m² surrounding area have been protected. Downstream of the waterfall, a former swimming pool has been converted into the Sundlaugin (Icelandic: The Swimming Pool) recording studio, where the band Sigur Rós recorded, among other things, their album "( )", the fifth track of which is titled "Álafoss".
