Fosslaug near Varmahlíð in the Skagafjörður region of northern Iceland is a remote natural hot pot set at the base of the Reykjafoss waterfall, where silica-rich geothermal water fills a small rock pool with the sound and mist of the falls as the only accompaniment — accessible via a short hike across classic Icelandic highland terrain of grass and lava. The combination of geothermal pool and active waterfall in a remote pastoral landscape without any facilities or infrastructure represents the purest form of Icelandic hot pot experience, where the spring's qualities are encountered in their natural state without mediation. Skagafjörður's surrounding landscape, famous for Iceland's finest horse breeding traditions and the dramatic medieval feudal history chronicled in the Sturlunga saga, adds historical depth to one of Iceland's most naturally rewarding hot spring hikes.
