Fjaðrárgljúfur
📍 Near Kirkjubæjarklaustur, South Iceland
A serpentine canyon on Iceland's south coast, roughly two kilometres long and up to about 100 metres deep, its dark palagonite walls draped in green moss with the Fjaðrá river winding along the bottom — one of the country's most photographed gorges.
What makes it marvelous
Fjaðrárgljúfur was cut by the Fjaðrá river into soft palagonite bedrock, a rock born of glacial meltwater flooding over volcanic ash. As the meltwater surged at the end of the last Ice Age and the river kept working afterward, it carved a tight, twisting slot up to about 100 metres deep and some two kilometres long. The walls curve back and forth in sculpted buttresses, and in summer they turn deep green with a thick coat of moss — the soft, slow-growing kind that gives so much of Iceland's young volcanic ground its velvet look.
Why visit
A marked path runs along the canyon rim past a series of viewing platforms, each opening a new bend of the gorge with the river far below. The scale and the sinuous shape make it feel carved for effect, and the mossy walls glow in low sun. It sits just off the Ring Road, an easy pause between the waterfalls of the south coast and the glaciers further east.

What to know before you go
🗓️ Best time
Late spring through autumn, when the rim path is open and dry and the moss is at its greenest; the canyon is often closed in early spring and after heavy rain to protect the fragile vegetation from erosion.
🧭 Getting there & access
About 250 km southeast of Reykjavík, a few kilometres up a side road off the Ring Road near Kirkjubæjarklaustur. A car park sits at the canyon mouth; a rim trail with platforms follows the top. Access is free but subject to seasonal and weather closures.
Good to know
- Stay on the marked rim path and behind the ropes — the moss and edges are fragile and unstable.
- Check whether the canyon is open before you go; it closes at times to let the vegetation recover.
- Low morning or evening light rakes across the mossy walls and brings out the curves.

Fjaðrárgljúfur is a canyon that seems to have been drawn rather than eroded. The Fjaðrá river cut it into palagonite — a soft, dark rock formed when glacial meltwater floods over volcanic ash — and over the long thaw at the end of the last Ice Age, and the slower work of the river since, it deepened into a tight, twisting slot up to about 100 metres deep and roughly two kilometres long. The walls fold back and forth in smooth buttresses, and through the summer they wear a thick coat of the slow-growing moss that softens so much of Iceland’s raw volcanic ground.
A rim path with viewing platforms follows the top of the gorge, each turn revealing another curve with the river threading the shadows below. That beauty has come at a cost: a burst of fame a few years ago brought crowds the fragile moss and narrow edges could not bear, and the site now closes at times — often in the thawing spring and after heavy rain — to let the ground recover. Visited with that care, on the marked trail and behind the ropes, it remains one of the most striking short walks on the south coast, an easy stop between the great waterfalls to the west and the glacier lagoons to the east.
