Canyons of Iceland: Fjaðrárgljúfur, Stuðlagil & More
Deep gorges carved by glacial rivers through volcanic rock, from moss-covered walls to columnar basalt.
Tip
Stay on marked paths
Canyon edges can be slippery and unstable, so respect barriers and closures.
Iceland's canyons were carved over thousands of years by glacial meltwater rivers cutting through soft volcanic rock: basalt, palagonite, and hyaloclastite. The country's largest, Jökulsárgljúfur, stretches 25 km through Vatnajökull National Park and houses three major waterfalls. The most photographed, Fjaðrárgljúfur, is 100 m deep and 2 km long. For basalt column formations, Stuðlagil in East Iceland became widely known after the Kárahnjúkar dam (2009) reduced water levels and revealed its columnar walls. Highland canyons like Sigöldugljúfur require F-road access (typically mid-June to September) and a 4WD vehicle, and see far fewer visitors.

North IcelandLargest canyon
Jökulsárgljúfur
Iceland's largest canyon at 25 km long and up to 100m deep. Part of Vatnajökull National Park. Home to Dettifoss, Selfoss, and Hafragilsfoss waterfalls.
HighlandsValley of Tears
Sigöldugljúfur
The 'Valley of Tears': dozens of small waterfalls cascade down the canyon walls at once. Highland F-road access keeps visitor numbers low.
East IcelandBasalt column canyon
Stuðlagil
Canyon lined with tall hexagonal basalt columns. A turquoise glacial river runs through it. Two access points: east side (easier) and west side (river crossing required).
South IcelandNarrow gorge
Stakkholtsgjá
Narrow gorge in Þórsmörk accessible by wading through a shallow stream. Towering moss-covered walls. Featured in film and TV. Requires river crossing to reach Þórsmörk.
North IcelandWaterfall canyon
Kolugljúfur
Canyon with multiple waterfalls along the Víðidalsá river. Viewing platforms on the bridge above. Named after the giantess Kola from Icelandic folklore.
South IcelandHidden canyon
Múlagljúfur
Relatively unknown moss-covered canyon with waterfalls. Short but steep hike to reach. Growing in popularity but still uncrowded compared to famous canyons.
North IcelandEcho rocks
Hljóðaklettar
Rock formations in Jökulsárgljúfur with twisted basalt columns and echo chambers. Hiking trails wind through the formations. Part of Vatnajökull National Park.
