On a two-day trip with Svalbard Wildlife Expeditions (Nov–May) to Lars Glacier on Spitsbergen, you’ll sleep in a caves (with a mat and sleeping bag) beneath a starry ceiling of ice crystals.
Spend a winter’s night in a glass bubble in Iceland’s 5 Million Star Hotel (Sept–Mar) and watch the northern lights dance across the sky from your bed.
The first ice hotel opened in Jukkasjarvi in 1989, and was rebuilt every winter. Now, a permanent addition sees part of it open year-round, so you can sleep on ice in any season.
Traditional Lappish igloos don’t use ice but snow instead, and it’s an easy skill to learn. On an overnight igloo-building stay in Rovaniemi ( Dec–Apr), you’ll spend about six hours building a shelter in prime aurora-viewing territory.
On a trip to Union Glacier, you can spend a night at 90º South. You’ll fly to the ice runway at South Pole Station, from which it’s a 1km walk across 3,000m-thick ice to a seasonal camp (Jan only) at the bottom of the world. The cost of this six-day adventure? A cool £42,000.
