Introduction

Fagradalsfjall sits in the middle of the Reykjanes peninsula, east of Grindavík, with its highest peak Langhóll at 385 m and about 40 km from Reykjavík. It is a tuya — a name meaning "beautiful valley" — and the most easily approachable active volcano on the North Atlantic rift. After roughly 815 years of quiescence a fissure opened in Geldingadalir on 19 March 2021 and lava flowed until 18 September; a second eruption ran from 3 August 2022 to 21 August, and a third on the north flank near Litli-Hrútur from 10 July 2023 to 5 August. All three were effusive — no explosive activity, just lava spreading slowly along the valleys into fields several metres thick, with spatter cones built up around each vent. In September 2022 the Catalogue of Icelandic Volcanoes split Fagradalsfjall off from the neighbouring Krýsuvík system as a volcano in its own right. All three eruptions are now over: what remains is cooled black lava, stacked spatter cones and steam from the fissures, and the volcano is currently dormant. The nearby Sundhnúkur eruption site remains closed to the public.

✨ Highlights

1
Spatter cones
Successive eruptions left stacked cones, the tallest row close to 30 m; walk close enough to read the layering and vesicles.
2
A lava desert
Roughly 3 sq km of lava field between Geldingadalir and Meradalir, with ropy and blocky surfaces that look like the far side of the Moon.
3
Steam up close
The fissures still hold heat, and on calm clear mornings steam columns rise visibly — the most direct sign of residual geothermal activity.
4
On a plate boundary
This is the North Atlantic rift itself, where the crust is still pulling apart by a few centimetres a year.
5
A hike-to-the-vent volcano
Twenty to forty minutes from the car park puts you at the eruption site — one of the very few active volcanoes in the world you can walk to on your own.
6
Up Langhóll
Continuing to the Langhóll ridge looks down over the whole lava field and the peninsula; budget an extra hour round trip.

🛈 Practical Info

→Duration：2–4 hours including the walk back and photos; add about an hour for Langhóll. The short loop with children takes 1.5–2 hours.
→Transport：Drive road 427 (Suðurstrandarvegur), about 45 minutes from Reykjavík. No bus serves it; guided tours and private cars depart from the city.
→Safety：Iceland's Environment Agency forbids walking on the lava — the crust breaks easily over lava tubes still hundreds of degrees hot. The lava is protected under Article 61 of the Nature Conservation Act: no throwing stones, no inscriptions.
→What to wear：Grippy hiking boots, a waterproof windproof shell and warm layers. Wind here regularly exceeds force 5, and in winter the daylight is short.
→Check first：Read the latest notices on visitreykjanes.is and SafeTravel.is before leaving, plus the Met Office volcano data. The neighbouring Sundhnúkur site is still closed — do not climb the barriers.
→Worth it?：Yes. With no flowing lava you are looking at the landscape itself, and a clear morning is better for photos than a night visit. A new eruption would be one of the closest opportunities of its kind anywhere.
→Watch out：The lots are camera-monitored; failing to pay adds a surcharge and a claim, usually issued the next day but payable later from your hotel. Some tours bundle this with the Blue Lagoon, but the two are about 25 km apart — allow over 40 minutes by road.
→Opening Hours：Open around the clock with no closure days. The trail is unlit at night and should be avoided in rain, snow or poor visibility.
→Ticket Information：No entrance fee. Parking ISK 1,000 per car, valid 24 hours, paid online via Parka — no cash on site. Lots P1 and P2 charge the same and are camera-monitored.
→Transportation：Drive road 427 (Suðurstrandarvegur), about 45 minutes from Reykjavík. No bus serves it; guided tours and private cars leave from the city.

💡 Tips

• Walking on the lava is prohibited by the Environment Agency and the easiest way to get hurt here — stay on the marked paths.
• Install Parka and add your plate before you arrive; there is no cash window and a failed on-site scan is camera-recorded.
• Wind is usually lightest at dawn and dusk; the midday crosswind affects both footing and photography.
• With children, stick to the short line from lot P1 to the first lava field — about 1.5 hours — and do not stray from it on the way back.
• There is summer twilight but the trail is unlit; night walks need a headlamp and are not advised.
• No shelter or supplies in the lava field. Wind chill runs well below the air temperature, so protect cameras and phones from grit.
