Flúðir

Golden Circle

Flúðir is a small farming village where geothermal energy is put to practical use at an unexpected scale. The Flúðasveppir mushroom farm here — the only commercial mushroom operation in Iceland — produces around 11 tonnes of button, chestnut, and portobello mushrooms per week using geothermal-heated greenhouses, and offers farm tours that show how Iceland harnesses underground heat for year-round food production. The village's main draw is the Secret Lagoon (Gamla Laugin), built in 1891 and considered Iceland's oldest swimming pool. It sits in the geothermal area of Hverahólmi just outside the village, where small geysers puff and hot springs bubble around the pool's edge. The setting feels far more natural and low-key than the larger spa complexes elsewhere on the Golden Circle. Flúðir sits just off the Golden Circle route, roughly 90 minutes from Reykjavík, and is quieter than Geysir or Gullfoss — a reasonable overnight base or lunch stop. Hrunalaug, a small natural hot spring on private farmland, is also a short detour from here.
