Skafta (Skaftá): A Flood-Prone Glacial River
A glacial river flowing from near Vatnajökull through the Skaftárhreppur district, historically prone to jökulhlaups and tied to the 1783 Laki eruption.
Region
South Iceland
Volcanic history. Monitor jökulhlaup alerts.
Quick Answer
Skaftá is one of Iceland's most historically significant rivers. Its source lies near geothermal cauldrons under the Vatnajökull glacier, which makes it prone to jökulhlaups: sudden glacial outburst floods that can multiply the river's flow many times over. The river gives its name to the Skaftá Fires of 1783, when the Laki fissure eruption sent lava into its gorge; the consequences were felt across the Northern Hemisphere.

Jökulhlaup warnings are issued by the Icelandic Met Office. Take all alerts seriously: glacial floods can arrive with little notice and quickly change river conditions.

Warning
Jökulhlaup risk
Check IMO alerts before visiting; floods can occur with little warning.
What to Expect at Skaftá
- Glacial river with variable flow depending on geothermal activity
- Lava fields from the 1783 eruption visible along the river
- Remote landscape with volcanic geological features

How to Get to Skaftá
- Crosses Route 1 (Ring Road) in the Skaftárhreppur district
- Located between Kirkjubæjarklaustur and Vík
- About 3.5 hours east of Reykjavik by car
- Multiple viewpoints visible from the Ring Road
- Laki craters require F-road access (4x4 recommended)
Best Time to Visit Skaftá
- Summer (June–August): Best access to Laki craters and highland trails
- Glacial floods also occur in winter; monitor current alerts
- Ring Road accessible year-round past the river
- F-roads to Laki open only in summer (typically July–September)
- Autumn brings quieter conditions
A flood record beyond the summer season
The Met Office’s December 2025 flood report confirmed drainage from the western Skaftá cauldron. By December 15 the flow at Sveinstindur had fallen, but conductivity remained elevated and the agency still warned of possible sulphur pollution near the glacier.
This winter event is a useful correction to advice that treats glacial floods as a summer-only concern. River level, dissolved geothermal material and gas are different measurements. Check current warnings for your route; a dated report that roads were unaffected in December 2025 is not a clearance for today.

Skaftá River FAQs
Quick answers with safety notes where it matters.
What are jökulhlaups and why is Skaftá prone to them?
Jökulhlaups are glacial outburst floods caused by geothermal activity melting ice beneath glaciers. Skaftá is particularly prone because its source lies near geothermal cauldrons under Vatnajökull, which periodically release massive volumes of meltwater.
What were the Skaftá Fires of 1783?
The Skaftá Fires (Skaftáreldar) was a devastating volcanic eruption from the Laki fissure in 1783–1784. Lava flowed into the Skaftá river gorge, and toxic gases caused a famine that killed about 20% of Iceland's population and affected weather across Europe.
Is it safe to visit the Skaftá river area?
The area is generally safe to visit, but jökulhlaup warnings must be taken seriously. Monitor the Icelandic Met Office and SafeTravel for alerts, throughout the year.
How do I get to the Skaftá river?
Skaftá crosses Route 1 (Ring Road) in the Skaftárhreppur district of South Iceland, between Kirkjubæjarklaustur and Vík. The river and its surroundings are visible from several points along the road.
What wildlife can I see around Skaftá?
The Skaftá river area supports Arctic char and brown trout. The surrounding wetlands attract various bird species including Arctic terns, golden plovers, and skuas. Seal colonies can be found where the river reaches the coast.
