Eruption site north-east of Grindavík
September, 2025: There is currently no active volcanic eruption in the Grindavík area.
– Even though the eruption has stopped it is still strictly forbidden to hike on the lava as the lava underneath might still be fresh.
– There is still a possibility of gas pollution in the eruption area, monitor gas pollution here: https://loftgaedi.is/?zoomLevel=11&lat=63.966904309995066&lng=-22.342057096747272
– Grindavik is open. Crevasses can be expected so stay on paths. The area is still considered hazardous due to volcanic unrest. In case of elevated threat level, evacuation sirens will be activated. Take notice where exits are to get out of town.
Eruption site (Fagradalsfjall – The old eruption site): From P1 is possible to hike to Fagradalsfjall, the old eruption site. The paths have challenging terrain with gravel, lava fields, uneven ground, and steep hills.

Do not walk on the lava under any circumstances. The lava might seem sturdy but the crust might be thin and hot lava underneath. Stay on marked pathways.
Pathways (information from https://www.visitreykjanes.is/en):
Path A – Mt. Fagradalsfjall (pink) to the eruption from 2021 and 2022 is about 6-8 km (one way), or about 2-2,5 hours of hiking. The distance depends on where you can park your car and how much hiking you do when reaching the eruption site.
Path C – Mt. Langihryggur (green) is about 4 km long (one way) to a viewing point of all the eruptions, from 2021, 2022 and 2023. From this path, you can see the lava from the new eruption by Mt. Litli Hrútur, but not the crater itself. Walking on the lava is dangerous and not allowed.
Path E – Meradalir (blue) to the new eruption site (July 2023) by Mt. Litli-Hrútur. The path is about 18–20 km (both ways). The first part of the hike is on a gravel path. The last 2 km over mossy lava rocks. It can take 5-6 hours in total to hike (not including a stop for viewing). It can be challenging. There are nice viewing spots on the way and remember that walking on the lava is dangerous and not allowed.
