About this spring
This completely natural hot spring pool is built from rough river stones and turf directly along the banks of the rushing Svartá river. The pool sits just a few meters away from the dramatic Reykjafoss waterfall, allowing bathers to hear the roaring cascade while soaking. The remote setting offers an untouched, peaceful bathing experience amidst the rolling hills of Skagafjörður.
Highlights
History
The spring was originally utilized during the early settlement era, with historical mentions in regional sagas regarding travelers resting by the thermal waters of the valley.
Local farmers constructed the simple stone walls of the current pool in the mid-twentieth century to contain the warm thermal flow. It remains completely unmonitored and wild, surviving as a cherished hidden gem of the northwest region.
Local guide
Finding Fosslaug requires a short drive through the rural farmlands of Skagafjörður followed by a peaceful walk along a grassy riverbank. As you walk, the roaring sound of the Reykjafoss waterfall grows louder and louder. Tucked right next to the rushing, icy Svartá river, you will find a small pool built from rough stones and natural turf.
The experience of bathing here feels completely wild and untouched by commercial tourism. The pool holds a comfortable temperature that contrasts beautifully with the chilly northern air. As you sit submerged in the thermal water, you can look across the grass and see the dramatic cascade of the waterfall tumbling into the canyon. The mist from the river mixes with the rising steam of the spring.
There are no changing rooms, paths, or staff at this remote location. You will need to change directly on the grass, so bringing a large towel or a waterproof ground mat is highly practical. Be sure to carry a headlamp if you plan to visit late in the evening during the autumn months.
The site is completely free and open to the public, offering total solitude during the early morning hours. It is one of the best hidden gems in Northwest Iceland for travelers seeking a deep connection with nature. There are no services nearby, so stock up on food and fuel in the town of Varmahlíð before heading out.
Mineral chemistry
Water character inferred from mineral type — verify on site.
Simple thermal springs have lower dissolved mineral content but are valued for the pure therapeutic effect of heat immersion itself — easing muscle tension and improving circulation. Considered the gentlest introduction to hot spring bathing.
Standard precautions apply: avoid bathing within 30 minutes of eating, keep soaks to 10–15 minutes for first-timers, and hydrate before and after.
