Eruption History and Timeline
No volcanic eruption had occurred for 815 years on the Reykjanes Peninsula until 19 March 2021. Fagradalsfjall had lain dormant for 6,000 years before the eruption fissure appeared in Geldingadalir to the south of Fagradalsfjall mountain.
The 2021 eruption started at approximately 20:45 local time on 19 March 2021. Fresh lava continued to emerge sporadically until 18 September 2021. The rim of the volcano had risen to a height of 334 metres above sea level by September 2021.
A second eruption began on 3 August 2022 after over 10,000 recorded earthquakes from 30 July to 3 August. An estimated 12 million cubic metres of lava erupted before it ceased on 21 August 2022. Over 1,830 people visited on the first day of the 2022 eruption.
A third eruption appeared near Litli-Hrútur on 10 July 2023. The initial lava flow was estimated to be 10 times more than the first eruption. Multiple eruptive fissures stretched for over 1 kilometre between Fagradalsfjall and Keilir. Volcanic activity at the site ceased on 5 August 2023.

Hiking to the Lava Fields
The hike to the site is around 6-8 kilometres each way. Hiking time takes around 3-6 hours depending on fitness and conditions. Many parts of the route are extremely steep with uneven rocky ground.
The route is poorly signed due to the recency of the eruption. Terrain changes constantly as lava cools and new paths form. Dress in layers and bring more water than you think you need for the exposed trail.
The trailhead is accessible from paved Road 427, but the path itself is challenging. If you prefer less demanding terrain, consider a day trip from Reykjavík with easier walking. You can also take a helicopter tour for aerial views.
