ELDGJÁ IN SHORT

Eldgjá (“Fire Canyon”) is a huge volcanic fissure in the southern Highlands of Iceland, with a main canyon of about 8.5 km. It is reached by the F208 mountain road, which is open only in summer and only for 4x4 vehicles with river crossings. It is free to visit, and most people spend a few hours here, including the walk to Ófærufoss waterfall.

About Eldgjá

Eldgjá is the biggest volcanic canyon in the world. It is part of a fissure system that runs for around 70 km from the Katla volcano under Mýrdalsjökull towards Vatnajökull. The most striking part is a canyon about 8.5 km long, up to about 600 metres wide and around 150 metres deep, with steep walls of black and red rock.

The main attraction is Ófærufoss, a two-tiered waterfall where the river Nyrðri-Ófæra pours into the canyon. Until 1993 a natural stone arch spanned the top of the lower fall. It collapsed into the river, and today only the falls remain. You walk along the canyon floor from the car park to reach it, and it is well worth the effort.

Eldgjá is remote. The road in is rough, and there are no services. But if you have the right vehicle or a guide, it is one of the most impressive places in the Highlands, and it is far quieter than Landmannalaugar next door.

The biggest lava eruption in a thousand years

Eldgjá erupted around 939 AD, in one of the largest volcanic events in Iceland’s history. Two lava fields covered about 780 km², and the lava, some 18.6 cubic kilometres, was the biggest flow of the last 1,100 years. The eruption is thought to have had effects far beyond Iceland.

The lava flows from Eldgjá and from the 1783–1784 Laki eruption are among the largest since the ice age. The area is part of Katla UNESCO Global Geopark, and Laki lies to the north-east.

How to get to Eldgjá

By car (4x4 only)From Reykjavík, follow the Ring Road (Route 1) along the south coast, past Vík. About 25 km before Kirkjubæjarklaustur, turn left onto Route 208 (Skaftártunguvegur). Keep on it as it turns into the mountain road F208 (Fjallabak Nyrðri), until a sign points right to Eldgjá and Ófærufoss. You need a 4x4 vehicle. Expect gravel and river crossings. Allow about 4 hours from Reykjavík.
On a guided tourThe safest way to reach Eldgjá. Some super-jeep and highland tours include Eldgjá and Ófærufoss, often with Landmannalaugar or Laki.
By public transportIn summer, a highland bus route serves the Landmannalaugar area, but there is no service to Eldgjá that we can confirm. A tour or 4x4 is the sensible choice.
Walking to ÓfærufossFrom the parking area, a marked path leads to a viewpoint over Ófærufoss. The walk is short, but the ground is uneven.

F-roads are closed in winter and typically open around June, depending on snow and river levels. Always check road.is and umferdin.is for the current status before you drive. Rental car insurance usually does not cover river crossings or F-roads unless stated.

Best time to visit Eldgjá

Summer (late June–September)The only time you can normally get in. Roads are open and daylight is long. Expect some traffic in July and August.
Winter (October–May)F208 is closed and the highlands are covered in snow. Not accessible for ordinary visitors.

Safety and practical tips

  • Only drive F208 in a proper 4x4. Cross rivers only if you know how, and check depth and current first.
  • Check road.is and umferdin.is for road status before you set off.
  • Fill your tank before you leave the Ring Road. There is no fuel in the highlands.
  • Bring warm, waterproof clothing. Weather can change quickly in the highlands.
  • Stay on paths and keep behind barriers. Canyon edges are steep and unstable.
  • Tell someone your plan and register on safetravel.is. Phone signal is patchy.

Facilities and accessibility

There are basic facilities near the parking area (information and picnic areas run by the Katla Geopark and national park). Do not rely on a café, shop or fuel. Bring food, water and spare clothes.
