Mývatn in October: Walks, Geothermal Sights and Where to Base

October at Mývatn means quiet trails, steaming ground and the first serious frosts — here is how to plan the walks, the sights and the drive times before the snow settles.

What October Actually Feels Like Around the Lake

Mývatn sits at roughly 280 metres in northeast Iceland, and October is the month the character of the place shifts. Daytime temperatures hover a few degrees above freezing and frost is common overnight, but the lake rarely freezes before November. Daylight falls from about eleven hours at the start of the month to eight by the end, which is still enough for two separate outings a day if you start before ten. Midges, the summer curse of the lake, are gone. So are most tour buses, which changes the atmosphere at the main sights considerably.

Rain and sleet arrive in short squalls rather than all-day drizzle, and wind off the lake makes it feel colder than the thermometer suggests. Pack a waterproof shell over a warm mid-layer and footwear with grip; the boardwalks at the geothermal sites frost over in the early morning and stay slick in shaded sections. Roads are usually clear, but the stretch of Route 1 over the Mývatnssveit plateau can ice up after dark. Check road conditions daily and avoid driving the highland tracks, which close for the season.

Walks Worth Doing and Sights Worth Skipping

The classic short walk is the loop at Dimmuborgir, the lava labyrinth south of the lake: around two kilometres on marked paths, an hour at an easy pace, with the Kirkjan arch as the natural turning point. Nearby, the climb up Hverfjall crater takes roughly forty-five minutes return; the rim path is loose and steep but the view over the lake and the pseudocraters at Skútustaðir is the best in the area. Skútustaðir itself has a flat thirty-minute circuit among the craters, suitable for anyone who wants distance without elevation.

At Hverir, the bare geothermal field below Námafjall, stay on the marked paths and keep upwind — the sulphur smell is strong and the ground crust is thinner than it looks. The Mývatn Nature Baths, a few kilometres east of Reykjahlíð, are quieter and cheaper than the Blue Lagoon and open into the evening; book a slot rather than arriving hopefully. Skip the full circuit of the lake by car if you only have half a day — the eastern shore is mostly flat farmland and better saved for a drive to Dettifoss, about forty-five minutes north on Route 862, where the gorge is genuinely impressive in autumn light.

Where to Base: Reykjahlíð, Skútustaðir or Akureyri

Reykjahlíð, on the northern shore, is the practical choice for a two-night stay. It puts Hverir, the nature baths, Dimmuborgir and Hverfjall all within ten to fifteen minutes by car, and the village has a fuel station and a small shop that keeps useful hours. Skútustaðir, on the south shore, is quieter and closer to the crater walks, but the drive around the lake to the northern sights adds about twenty minutes each way, which matters when daylight is shrinking.

Akureyri, roughly an hour and a quarter west on Route 1, works if you want a larger town with restaurants and a wider hotel choice, but it turns every Mývatn outing into a day trip. My recommendation for an October visit is two nights in or near Reykjahlíð and a third in Akureyri on the way back to the airport, which gives you the lake without rushing and a comfortable final evening. Book early for the last week of October, when the winter season starts to close some smaller guesthouses.

Getting There and Making the Days Work

From Keflavík the drive is about five and a half hours via Route 1, or you can fly to Akureyri in under an hour and pick up a car there, cutting the drive to around eighty minutes. Most travellers do the drive in one push with a stop at Goðafoss, about forty minutes west of the lake, which is worth twenty minutes of anyone's time. Fuel up in Akureyri or Reykjahlíð; the stretches between are long and the stations thin out.

Structure your days around light rather than the clock. Start with a geothermal site in the morning while the ground is still crisp, take a longer walk after lunch, and keep the nature baths for late afternoon when the steam is most visible against a low sun. Keep one day flexible for weather — a clear October morning can turn a planned drive into the highlight of the trip, and the reverse is just as true. If aurora is on your mind, the dark shores near Skútustaðir give a wide northern horizon with little light pollution.

Questions, answered

Can you see the northern lights at Mývatn in October?

Yes, nights are dark enough from early October, and the low light pollution around the lake helps. Clear, cold nights after a front passes are best. Check the forecast each evening and drive to the south shore near Skútustaðir for open northern horizon.

Do you need a four-wheel drive for Mývatn in October?

Not for Route 1 or the paved roads around the lake. A normal car is fine unless snow arrives early. Highland tracks are closed or unsuitable, so do not plan on them. Winter tyres are standard on Icelandic rentals by October.

How many nights should you spend at Mývatn?

Two nights based near Reykjahlíð covers Dimmuborgir, Hverfjall, Hverir and the nature baths without rushing. Add a third night in Akureyri on the way back for a comfortable return drive and a wider choice of restaurants.
