Can you hike to the Fagradalsfjall eruption site?

When eruptions are not active, hiking trails lead to the lava fields from Fagradalsfjall. The hike is moderate (about 3–4 hours round trip). Check SafeTravel.is for current trail status as paths change with new lava flows and gas emissions.

Is Fagradalsfjall still erupting?

The Reykjanes Peninsula has experienced multiple eruption episodes since 2021. Check the Icelandic Meteorological Office (IMO) for current volcanic activity status, as eruptions in this area may continue intermittently.

Is volcanic gas a concern at Fagradalsfjall?

Yes, volcanic gas (primarily SO2) can be dangerous, especially in low-lying areas and valleys near the eruption site. Always check gas forecasts on IMO's website and carry a gas mask if recommended. Avoid depressions where gas can accumulate.

How far is Fagradalsfjall from Reykjavik?

Fagradalsfjall is about 40 km from Reykjavik and roughly 20 km from Keflavík International Airport. It is one of the most accessible volcanic sites in Iceland, located on the Reykjanes Peninsula.

Why was the 2021 eruption significant?

The March 2021 eruption at Fagradalsfjall was the first volcanic eruption on the Reykjanes Peninsula in approximately 800 years. It marked the beginning of a new eruptive period in the area that scientists expect could last decades or centuries.

Region

Reykjanes Peninsula

Near Keflavík. Check gas and trail status first.

In March 2021, lava began flowing from a fissure near Fagradalsfjall, ending 800 years of volcanic dormancy on the Reykjanes Peninsula. Multiple eruptions have followed, creating new lava fields that visitors can hike to when conditions allow. Its proximity to both Reykjavik and Keflavík airport makes it one of the most accessible active volcanic areas in the world.

How to Get There

Drive Route 43 or Route 427 from Grindavik/Keflavik area to signed parking lots (~40 km from Reykjavik)
Trailhead parking locations change with each eruption—check safetravel.is for current access points
No F-road required: paved or well-maintained gravel roads to parking areas
Moderate hiking trail: 3-4 hours round trip over uneven lava terrain; sturdy hiking boots essential
No guided tour required for lava field hikes, but guided tours available from Reykjavik with transport
Carry a gas mask or respirator (available at outdoor shops in Reykjavik) if SO2 levels are elevated

Best Time to Visit

Year-round access to lava fields when trails are open and gas levels are safe
During active eruptions: check safetravel.is daily—access may open/close based on lava flow direction
June to August: longest days, best weather for hiking; midnight sun allows late evening visits
Winter: lava fields accessible if gas-safe, but shorter days and potential ice on trails
Between eruptions: cooled lava fields offer safer, gas-free exploration of volcanic features
Wind direction matters: westerly winds push gas away from main hiking approaches
