January is Iceland with the filters off. The festive crowds leave after New Year’s, prices drop to their yearly floor, and the country settles into its deepest winter: ice caves at their most stable, aurora nights at their longest, and landscapes under proper snow. It demands flexibility and rewards it. This is the month for travelers who want winter Iceland without sharing it.
Why January Works
Daylight grows from about 4.5 hours on January 1 to nearly 7 by month’s end, and the low sun never really climbs, which means the entire short day is golden hour. Temperatures in Reykjavík hover around 27 to 36°F (minus 3 to plus 2°C); the north runs colder. Storms are a genuine factor, so the January rule is simple: one anchor activity per day, buffer days in any itinerary, and road.is checked every morning like a ritual.
The Best Things to Do in Iceland in January
1. The Crystal Ice Caves
January is arguably the single best ice cave month: deep cold keeps the blue chambers under Vatnajökull stable, and the post holiday lull means smaller groups. Tours run by super jeep from Jökulsárlón. Book before you fly; the season’s best caves are known by now and demand is real.
2. Northern Lights at Full Strength
With 17+ hours of darkness, January maximizes raw aurora opportunity. The method never changes: vedur.is for cloud cover and activity, escape the town lights, allow several nights. January’s gamble is weather; its payoff is displays over snow covered country, which doubles the spectacle.
3. The South Coast in Ice
Seljalandsfoss behind a chandelier of icicles, Skógafoss framed in white, Reynisfjara’s black sand dusted with snow: the famous corridor is at its most dramatic and least crowded. Drive a 4WD, pack boot spikes for the frozen paths, and keep daily distances short.
4. Þorrablót: Eat Like a Viking
From late January (the old month of Þorri begins), Icelanders hold feasts of the traditional survival foods: fermented shark, smoked lamb, blood pudding, sour ram delicacies, all chased with brennivín. Restaurants serve Þorri platters and visitors are welcome to test their courage. It is the most culturally Icelandic thing you can do all year.
5. Snowmobiles, Glaciers, and Super Jeeps
Langjökull snowmobiling from the Golden Circle, glacier hikes on Sólheimajökull (they run all winter with crampons), and super jeep tours into highlands no rental car may enter. January conditions make guided power the smart way into the wild.
6. Bathe While It Snows
The Blue Lagoon, Sky Lagoon, the Secret Lagoon, and every municipal hot tub in the land hit peak value in January. Snow falling into 38 degree water is the image people keep.
7. Reykjavik Between Adventures
The capital in January: Þorrablót menus, the cozy season in cafés and bookshops, museum afternoons, and from late January the buildup to February’s Winter Lights. Hotel rates are the year’s best.
8. Ski the North
Hlíðarfjall above Akureyri opens its season properly in January, with floodlit evening skiing through the dark months and fjord views from the lifts.
January Practicalities
Fly into the storm aware: itineraries need slack, and travel insurance that covers weather disruption earns its fee this month. Rent 4WD with studded winter tires (standard on rentals now), drive slower than feels necessary, and treat road closures as final. Pack thermals, a real parka, waterproof boots, ice grips, and swimwear. Base yourself in Reykjavík and the South Coast unless you are an experienced winter driver.
