Iceland's Lava Fields and Craters: Where to Walk Safely

Eldhraun and the South Coast: Easy Walks on Old Lava

Eldhraun, the moss-covered basalt field that spread from the 1783 Lakagígar eruptions, runs alongside the Ring Road between Kirkjubæjarklaustur and Vík. The short signed paths near the Skaftá river bridge let you see the cushiony moss at close range without stepping on it; a single footprint can take decades to heal. Stop at the Kirkjubæjarklaustur visitor information point for maps, and keep to marked boardwalks. The drive from Vík takes about 45 minutes, and the light is best from May to early September, when the moss is vivid and the roads are reliably open.

Further east, the Fjaðrárgljúfur canyon paths and the Eldhraun viewpoints near Hjörleifshöfði give you short walks of 20 to 40 minutes on gravel and boardwalk. The ground here is uneven but not technical, so trainers are fine in dry weather. You will see the mossy lava from the road long before you park; resist the urge to climb the uneven ridges, as the crust is fragile and hides holes. For an overnight base, Vík has the widest choice of guesthouses and small hotels, and booking ahead for June to August is wise because rooms in the village fill quickly.

Snæfellsnes: Crater Rims and Coastal Lava

On the Snæfellsnes peninsula, the Eldborg crater near the farm of Hnausar is a classic short climb: roughly 40 minutes up and back on a marked trail, with a grassy rim you can walk around without touching the fragile inner walls. The lava field around it, Berserkjahraun, is crossed by a walking path from the car park off Route 54. The drive from Reykjavík is about two hours; from Stykkishólmur, 40 minutes. Late June to August offers the driest trails, though the peninsula is often windier than the south coast, so a shell jacket earns its place in your bag.

West of Hellnar, the Saxhóll crater has a wooden staircase to the rim, installed to protect the cone from erosion, and the view over the surrounding lava and out to the sea takes about 15 minutes each way. Nearby, the Djúpalónssandur beach path crosses old lava and black pebbles; stay well back from the water line. Base yourself in Grundarfjörður or Arnarstapi for two nights if you want to combine these walks with the national park trails. Snæfellsnes hotels are smaller than Reykjavík's, so book well before the summer season rather than leaving it to the last week.

Mývatn and the North: Craters with Facilities

The Mývatn area is the most rewarding region for crater walking with straightforward access. The Skútustaðagígar pseudocraters by the lake have a short loop path of about 30 minutes, suitable for families, with the trailhead at the roadside car park. East of the lake, the Hverfjall crater rim trail climbs about 20 minutes to a marked path around the top; stay on the path, as the loose inner slopes are unstable and the crater is protected. The drive from Akureyri takes roughly 45 minutes, and the area is best from June to early September when the highland-adjacent tracks are open.

For lava rather than craters, the Dimmuborgir formations near Mývatn have signed loops of 30 to 90 minutes through lava pillars and arches; the ground is uneven, so wear proper shoes. The Leirhnjúkur lava field near Krafla, about 15 minutes further north, has a boardwalk over geothermal ground and recent lava, and it is one of the few places where you can walk close to active geothermal features safely. Base in Reykjahlíð for one or two nights; the village has a handful of hotels and guesthouses, and the Mývatn Nature Baths make a good end to a walking day.

What to Skip, and Where to Sleep

Skip the temptation to walk onto unmarked lava anywhere near an active eruption site; the 2021 Fagradalsfjall and later Reykjanes eruptions drew crowds, but access roads close and conditions change. If an eruption is under way on the Reykjanes peninsula, follow the official guidance and the marked viewing areas near Grindavík rather than finding your own route. Also skip the highland tracks such as Landmannalaugar in a standard car; the F208 needs a 4x4 and is usually open only from late June to September. Bus tours from Reykjavík to the south coast are a sensible option if you do not want to drive, and they usually include Eldhraun and the Vík area.

For a hotel base, I would book two nights in Vík for the south coast lava fields and two in Reykjahlíð for Mývatn, adding a night in Grundarfjörður if Snæfellsnes is on your list. Reykjavík works as a first and last night, with the Ring Road drive to Vík taking about 2.5 hours. Expect higher room rates in July and August than in May or September, and book early for those peak months. Prices vary by season and property, so compare a few options and confirm cancellation terms before you commit.
