Seljalandsfoss

The Seljalandsá river reaches the edge of the Eyjafjöll cliffs and falls in one narrow ribbon to a pool below. From the front, the height and slim shape are easy to read. From the side and back, when the path is open, the water becomes a moving curtain with the South Iceland lowlands visible through the spray.

Official regional sources use slightly different measurements: Visit South Iceland gives 60 metres, while Katla UNESCO Global Geopark records about 62 metres. 'About 60 metres' is therefore the useful figure. The river begins on the western side of the Eyjafjöll range, below Eyjafjallajökull, rather than being described simply as a direct glacial outlet.

When relative sea level was higher, waves cut into the foot of the Eyjafjöll mountain range. The sea later retreated and broad lowlands developed in front of the cliff, leaving the former coastline far from today's shore. This explains the abrupt wall rising from otherwise flat farmland and why several waterfalls appear along the same edge.

The rock is layered rather than uniform. Katla Geopark identifies lava at the top of the fall, with palagonite tuff and breccia below. Water and spray continue to work on the softer cliff and hollow behind the cascade. The pool at the base is called Kerið, meaning 'the tub', and the open recess around it creates the waterfall's distinctive viewing path.

The recess changes the waterfall from a front view into an immersive walk through spray.

Begin at the main front view. From there, the path climbs toward the cliff, crosses wet and uneven ground, and passes behind the water before returning to the open side. Spray reaches clothing, glasses, and cameras quickly. Waterproof layers protect comfort, but secure footwear matters more because stone and packed ground can be slick.

This is not a step-free extension of the viewpoint. Narrow parts, slopes, rough surfaces, and visitors stopping for photographs can make the loop slow. A traveler who cannot use the back path still gets the complete outline of the waterfall from the front, so there is no reason to force the circuit when footing or mobility makes it uncomfortable.

• Keep both hands available on the wettest and narrowest sections.
• Protect electronics before entering the main spray zone.
• Give others room at pinch points instead of stopping across the path.
• Stay on the established route to protect vegetation and avoid unstable ground.

Ice can transform the cliff while making the path below it dangerous.

Fine mist freezes on the cliff, path, and roof of the recess. During a thaw, large pieces can break away. Visit South Iceland specifically warns that slippery paths and falling ice make it dangerous to approach the cliff or walk behind the waterfall in winter. The danger can continue during changing spring conditions, not just on the coldest days.

Before a winter visit, check the Icelandic Met Office forecast for South Iceland and SafeTravel for alerts. Waterproof clothing still matters in summer, but winter adds warm layers, daylight limits, and traction appropriate to the conditions. On-site signs make the final decision for the path itself.

The shorter end covers the front view and a calm look around the base. The longer end allows the walk-behind loop when open, several viewing angles, time to put away wet gear, and delays caused by a busy path. A closed back path usually shortens the stop without making the waterfall itself a disappointment.

The main viewing area is close to the spray, so even a short visit can involve wet gear.

Allow more time if you continue on foot to Gljúfrabúi. It is a separate waterfall experience, not simply another view of Seljalandsfoss. Families, photographers, and anyone changing layers or protecting equipment should keep the schedule loose instead of relying on a precise stop time.

Gljúfrabúi is the closest and most natural companion. It falls about 40 metres from the spring-fed Gljúfurá into a narrow chasm partly hidden by a large rock. Entering the wet gorge is more confined than the open path at Seljalandsfoss, and Katla Geopark warns of falling-rock risk. See it from a safe position if water, crowding, or footwear makes the inner approach unsuitable.

Farther east, Skógafoss gives a broad, powerful front-facing contrast. Nauthúsagil is a longer and more involved gorge walk, not an automatic addition. Hvolsvöllur provides nearby town context, while the South Iceland guide helps place the Eyjafjöll cliff line within the wider region.

Seljalandsfoss itself sits close to Road 1, but parking arrangements, weather, and road conditions can change. Check Umferðin before a winter or storm-affected drive and follow the site setup you find on arrival. These practical checks should support the waterfall visit, not become the main story.
