Hrunalaug Hot Spring

Hrunalaug is a small geothermal hot spring set among rolling farmland near Flúðir. Its warm, clear water and natural surroundings create a more intimate bathing experience than Iceland’s larger geothermal spas. The site has a long history of bathing and farming, with the oldest pool dating back to around 1890, while improved changing facilities now make visiting considerably more comfortable.

The History of Hrunalaug

Hrunalaug has been in the same family since the oldest part of the pool was built at Ás farm around 1890. This original pool was used both for bathing and washing laundry.

A second pool was built in 1935 for washing sheep, a practice used to protect the animals from sheep scab. Sheep bathing continued here until the 1980s.

As Hrunalaug became increasingly popular with visitors, a third pool was constructed in 2017. It was extensively renovated in 2023 and enlarged with an outer ring made from natural columnar basalt. Together, the three pools preserve different chapters of Hrunalaug’s history while continuing to serve as a geothermal bathing place today.
