What is Seljavallalaug?

Seljavallalaug is one of Iceland’s most unique and historic swimming pools. Nestled deep in a scenic valley and surrounded by steep mountains, this geothermal pool offers a raw and rugged experience unlike anything else in the country. Built in 1923, it is one of Iceland’s oldest manmade pools and was originally created as a place for locals to learn how to swim.

With natural hot water flowing into one side, the pool provides a warm soak in a completely open and remote setting. It is not part of any formal spa or complex, which makes it feel like a true Icelandic secret spot. There are no fences, ticket booths, or lifeguards — just nature and a pool built into the landscape.

Getting There

To reach Seljavallalaug, you’ll need to park near the small Seljavellir parking area and walk about 15 to 20 minutes into the valley. The hike is scenic and relatively easy, following a gravel path alongside a stream. It is not signposted, so make sure to check your route ahead of time.

The walk itself is part of the experience, and arriving at the pool surrounded by towering cliffs feels like stumbling upon something lost in time.

Pool Details

• Size: 25 meters long and 10 meters wide

• Water Source: Fed by a natural hot spring

• Water Temperature: Varies by season, not consistently hot — always test it before entering

• Admission: Free and open to the public

• Changing Facilities: Basic concrete huts on-site, often in poor condition

This is not a polished spa environment. The pool is cleaned only once a year, and algae tends to build up during the warmer months. In summer, it may even turn the water a bright green. The floor can get slippery, so caution is advised when walking or entering.

Things to Know Before You Go

• The changing rooms are very basic and frequently dirty. Many visitors choose to change outside or in their vehicles

• There is no staff or maintenance on-site, so you swim at your own risk

• Always respect the area by packing out all garbage and leaving no trace

• The pool is shared, so be courteous to others even if you arrive first

• The temperature varies and is not as warm as other hot springs

• The flow of water is limited, and with high foot traffic, it may not be the cleanest option for sensitive swimmers

Despite these warnings, many travelers still choose to visit for the experience and the unforgettable setting. It is one of those Icelandic places that feels untouched and full of history.

History and Local Significance

Seljavallalaug has been around for over a century and holds an important place in Iceland’s swimming culture. At the time of its construction, swimming was not a common skill in Iceland, despite the country’s maritime history. This pool helped educate generations of children and remains a symbol of that effort.

In 2010, when Eyjafjallajökull volcano erupted, the pool was filled with ash and unusable. It wasn’t until the next summer that a team of volunteers cleaned it out, restoring it for visitors once again.

Today, it stands as a reminder of both nature’s power and the resilience of the local community.

Is Seljavallalaug Worth Visiting?

If you are looking for a peaceful, remote, and Instagram-worthy stop, Seljavallalaug absolutely delivers. However, it is not for everyone. Those looking for a clean, well-maintained hot spring with full amenities might want to skip it. But if you are up for a bit of adventure and love the idea of soaking in a pool built into a quiet Icelandic valley, it is an unforgettable place.

Come prepared, leave no trace, and respect the natural surroundings — and you will be rewarded with one of the most atmospheric hot spring experiences in the country.
