Main image

Hekla is a high, conical stratovolcano in southern Iceland known for frequent eruptive activity in the historical record. The volcano has produced explosive and effusive eruptions and is one of Iceland’s best-known volcanic peaks.

The mountain’s steep profile and lava fields make it a prominent feature in the landscape; it is accessible by highland roads when weather and conditions permit and is visited by hikers when conditions are safe. Due to its eruptive history, approaches require caution and local guidance.

Hekla has been active in many periods since medieval times and has produced significant eruptions at intervals over the last millennium. Monitoring and hazard planning are in place because of its potential for sudden eruptions.

The volcano sits in southern Iceland within the broader volcanic zone that crosses the island.

  • Elevation: Summit elevation is 1,491 metres, making it one of Iceland's more prominent volcanic peaks and a visible landmark in southern Iceland.
  • Historic Activity: Eruptions have been frequent in the historical record, with large documented eruptions dating back to the early medieval period and a notable eruption in 2000.
