Seljavallalaug measures 10 meters (32 feet) wide and 25 meters (82 feet) long. Unlike many other pools, admission to Seljavallalaug is free.


How to get to Seljavallalaug

Seljavallalaug Basin is located near Route 1 (the main road) and Route 242 in the southern region of the country, approximately 23 kilometers (14 miles) from Seljalandsfoss waterfall and 11 kilometers (7 miles) from Skogafoss waterfall.

The hike to the basin takes around 15 minutes, but it is advisable to wear sturdy hiking shoes or boots. While the route is neither strenuous nor complicated, it traverses rocky terrain, and athletic shoes may not provide sufficient traction, especially in wet conditions.

Seljavallalaug pool cleanliness

In 2010, the eruption of the Eyjafjallajökull volcano covered Seljavallalaug and its locker room with mud and ash, seemingly putting an end to the pool’s operation. However, thanks to donations and the dedication of many individuals, the pool was successfully restored and reopened. Today, Seljavallalaug undergoes regular cleaning and maintenance once a year.


Seljavallalaug - changing room

Seljavallalaug offers the most basic facilities compared to most public pools. There are separate changing rooms for men and women, but they are quite primitive in nature.

While changing rooms are available at Seljavallalaug, their condition is somewhat neglected due to a lack of regular maintenance.

Depending on the source, the exact maximum depth varies slightly, but the consensus is that Seljavallalaug is about 1.8 meters (6 feet) at its deepest point, while the shallower areas are around 1.2 meters (4 feet) deep. The relatively shallow depth makes it unsuitable for serious swimming but ideal for basking and relaxing in the geothermal waters.
