Kakslauttanen Arctic Resort

There are places that exist in the collective imagination of travellers long before they are visited, and Kakslauttanen Arctic Resort is emphatically one of them. Sitting at 68 degrees north in the wilderness of Finnish Lapland, this collection of thermal glass igloos has become the definitive answer to the question that haunts every aurora hunter: where is the very best place on Earth to sleep beneath the northern lights?

The answer, it turns out, is inside a heated glass dome in a snow-dusted pine forest, 35 kilometres inside the Arctic Circle.

Yrjö Rissanen built the first glass igloo here in 1999, driven by a simple but radical idea: why should guests sleep indoors and only hope to glimpse the aurora from a cold window? Today, more than 65 glass igloos are scattered across the resort’s pine-forested grounds, each one a private observatory with a king-sized bed oriented perfectly toward the Finnish sky. The thermal glass is engineered to remain crystal clear even when temperatures plummet to -30°C: no condensation, no frosting, just an uninterrupted canopy of stars, and on the right nights, the green and violet curtains of the aurora borealis sweeping directly overhead.

What lifts Kakslauttanen beyond a simple novelty is the sheer quality of the surrounding experience. Days are structured around Finnish Lapland’s winter wilderness: snowmobile expeditions into the vast Urho Kekkonen National Park, reindeer-drawn sleigh rides through old-growth forest, husky safaris with teams of Siberian and Alaskan huskies whose collective enthusiasm is genuinely infectious, and ice fishing on frozen lakes where the silence is so complete it becomes a sound in itself.

The resort’s smoke sauna, one of the finest traditional saunas in Finland, is the ideal antidote to a day in the cold. The ritual of heating the smoke sauna for hours, then sitting in its ancient birch-scented warmth before rolling in fresh snow, is one of those experiences that defies easy description.

In the evening, the restaurant serves dishes that root you firmly in Lapland: reindeer carpaccio, smoked Arctic char, cloudberry desserts made with berries foraged from the surrounding bogs. After dinner, guests gravitate back toward their igloos, setting aurora alarms and scanning the sky with the particular focused hope that only cold, dark latitudes inspire.

Kakslauttanen is not a quiet, understated retreat: it is a genuine phenomenon, written about in every travel magazine, photographed millions of times, and deeply beloved by the hundreds of thousands of guests who have slept within its glass walls. Its popularity means advance booking is essential, sometimes more than a year ahead for December and January dates. But for those who secure their igloo, the reward is among the most visceral travel experiences on the planet: lying in a warm bed, watching the sky turn colours that have no earthly equivalent, in one of the darkest, most remote corners of Europe.
