Where Is Seljavallalaug Located?
Seljavallalaug Swimming Pool sits on Iceland’s South Coast in a narrow mountain valley called Seljavellir, beneath the Eyjafjallajokull Volcano. It’s located about halfway between the famous Seljalandsfoss and Skogafoss waterfalls and roughly 6 miles (10 kilometers) east of Asolfsskali Farm in South Iceland. The exact location is H98V+FC9, 861 Evindarhólar, Iceland.
The pool lies about 93 miles (150 kilometers) from Reykjavik, roughly a 2-hour drive, and is only a short detour from Route 1, the Ring Road. Its location makes it easy to include on South Coast trips, whether you’re driving from the capital or joining a guided tour.
History of Seljavallalaug Swimming Pool
Seljavallalaug Swimming Pool was built in 1923 by local volunteers led by Björn Andrésson Berjaneskoti. At the time, few Icelanders knew how to swim, even though many worked at sea. The pool was created to teach swimming and improve water safety in the community. For years after it opened, swimming lessons were held here as part of compulsory education.
Measuring 82 feet (25 meters) long and 30 feet (10 meters) wide, it was among the largest swimming pools in Iceland when it was built. It served as both a training site and a gathering place for locals before newer facilities were built nearby.
In 2010, the Eyjafjallajokull Volcano erupted, covering the pool and the surrounding valley with ash. A year later, volunteers returned to clean it by hand and restore it for use. Seljavallalaug remains protected today as one of Iceland’s oldest swimming pools and a reminder of the country’s connection to nature, community, and self-reliance.
Swimming in Seljavallalaug
The water in Seljavallalaug Swimming Pool is naturally heated by a nearby spring, but it’s not a hot tub. It feels lukewarm, with temperatures ranging from about 68 F to 86 F (20 C to 30 C), though it can reach up to around 95 F (35 C) in summer.
The warmest area is near the point where the spring flows in, while the opposite end can feel cooler, especially during winter. Because the spring continuously feeds fresh water into the pool, it stays safe for swimming despite its remote location.
The pool is cleaned once a year by local volunteers, so the water can appear cloudy or slightly green from algae buildup. This is normal and part of the pool’s natural condition. The surface and edges may be slippery, so you should move carefully when getting in and out. There are no lifeguards or attendants on-site, and swimming is entirely at your own risk.
Visitors are expected to respect the pool and the landscape. Alcohol is not allowed, and loud noise or large groups are discouraged to maintain the peaceful setting. The small changing shed nearby has no showers or running water, so it’s best to arrive prepared and leave no trace behind.
How To Get to the Seljavallalaug Swimming Pool
The drive to Seljavallalaug Swimming Pool from Reykjavik takes around 1.5 to 2 hours along the Ring Road. Head east from the capital toward the town of Hvolsvollur and continue past Seljalandsfoss Waterfall, one of the main landmarks along the route.
After passing Seljalandsfoss, look for the turnoff onto Route 242 marked Raufarfell. Follow this road toward the Seljavellir Valley until you reach a small parking lot at the end of the road. There are no official signs for Seljavallalaug, but the area is easy to find with GPS coordinates 63.5656° N, 19.6076° W.
From the parking area, the pool is about a 15- to 20-minute walk each way. The trail is mostly flat but follows a rocky riverbed with a few shallow stream crossings. Good shoes or hiking boots are recommended, as the ground can be uneven and slippery after rain. The pool is tucked behind a bend in the valley and only becomes visible near the end of the hike.
What To Bring When Visiting Seljavallalaug
There are no facilities at Seljavallalaug Swimming Pool apart from a small changing shed, so you should come prepared. Bring a swimsuit, a towel, and enough drinking water for the walk and swim.
Hiking shoes or boots with good grip are recommended, as the trail can be rocky and uneven. It’s also best to bring warm clothes to change into after swimming, since the valley can be windy and cool even in summer.
A waterproof bag is useful for keeping valuables dry, especially when crossing small streams on the trail. Those planning to take photos should carry a camera or phone with protection against water and ash dust. Because there are no restrooms, showers, or trash bins in the area, pack responsibly and take all waste with you when you leave.
Best Time To Visit Seljavallalaug Swimming Pool
Seljavallalaug Swimming Pool is open year-round, but the best time to visit is from late spring to early autumn, roughly between May and September. During these months, the trail is clear of ice, the weather is milder, and the valley is green and accessible. The walk to the pool is easier, and the water feels warmer in calm summer air.
In winter, the site remains open, but conditions are unpredictable. The trail can become icy or covered in snow, and daylight hours are limited. The pool stays at the same lukewarm temperature, but changing and walking in the cold can be challenging. If you plan a winter visit, bring proper gear and check weather updates before driving to the South Coast.
For the best experience, go early in the morning or later in the evening when the site is quieter. Even in peak season, Seljavallalaug is rarely crowded, and visiting outside midday hours gives you a better chance to enjoy the calm surroundings.
