Seljalandsfoss is one of Iceland’s most iconic and photographed waterfalls, located on the country’s scenic South Coast. Its elegant, narrow cascade plunges 60 meters from a former sea cliff, creating a shimmering curtain of water that is visible from afar. What makes Seljalandsfoss truly unique is the rare opportunity to walk behind the waterfall, offering a breathtaking view from inside a natural alcove carved by centuries of erosion. It is an experience that feels both immersive and unforgettable.
LOCATION AND DISTANCE FROM SELFOSS
Seljalandsfoss lies directly off the Ring Road (Route 1), making it one of the most accessible natural attractions in southern Iceland. From Selfoss, the drive is approximately 60 km, taking 45–50 minutes under normal road conditions. The journey follows one of the most picturesque stretches of the South Coast, with open farmlands, lava fields, and wide ocean views.
Along the way from Selfoss, travelers can stop at:
- Urriðafoss – Iceland’s most voluminous waterfall
- Eyjafjallajökull viewpoints
- River plains and mossy lava fields
- Farmsteads and ocean lookouts
This makes Seljalandsfoss not just a destination, but part of a naturally beautiful route ideal for day trips.
GEOLOGY AND FORMATION
The geological story of Seljalandsfoss is as fascinating as its appearance. Thousands of years ago, the waterfall’s cliff face marked the actual coastline of Iceland. As glacial periods shifted and sea levels fell, the ocean retreated, leaving behind a tall wall of basalt that once met the waves.
The water feeding Seljalandsfoss originates primarily from the Eyjafjallajökull glacier, a volcano famous worldwide for its 2010 eruption. Meltwater travels down its slopes through the Seljalandsá river before dropping dramatically over the ancient sea cliff.
A defining feature of the waterfall is the erosional cavity behind the cascade. Over millennia, the force of falling water carved out a natural hollow, making it possible for visitors to follow a circular footpath behind the waterfall, looking outward through a shimmering veil of spray. It is this rare geological structure that has made Seljalandsfoss one of Iceland’s most celebrated sights.
WHAT TO SEE AND DO ON SITE
Seljalandsfoss is exceptionally visitor-friendly, with a short, well-maintained path leading from the parking area directly to the main viewpoint.
The highlight is undoubtedly the walk behind the waterfall. Standing inside the rocky alcove, framed by mist and the roar of the falling water, is an unforgettable experience. Waterproof clothing is strongly recommended.
Nearby, just a few minutes’ walk north, is the hidden waterfall Gljúfrabúi, concealed within a narrow canyon. Entering it requires stepping through a small gorge with shallow water underfoot, but the reward is a magical, enclosed chamber with a vertical stream plunging from above.
On site, visitors will find:
- Public toilets
- A seasonal café or food truck
- A small souvenir stand
- Well-marked walking trails
Parking is available directly next to the waterfall, with a fee of 900-1000 ISK for the day.
