Frozen accommodation sounds like a novelty until you realise how much craft goes into it. Every autumn and early winter, teams across northern Europe harvest ice from rivers and lakes and pack tonnes of snow into moulds to build hotels that quite literally melt away each spring. Here are five worth booking.

In northern Norway, Snowhotel 365 at Snow Resort Kirkenes is the only one that never closes. Open all year, it needs around 30 tonnes of ice and fresh snow annually to keep its structure intact — and as the snow gradually hardens into ice, the walls and sculptures change texture over time. Each of its rooms is hand-carved by international ice sculptors, so no two are alike. Indoor temperatures sit around -4°C, but guests get thermal sleeping bags plus a heated lounge, sauna, showers, breakfast and a three-course dinner.

Sweden's ICEHOTEL in Jukkasjärvi is the original. It rebuilds from scratch each December as the Torne River freezes over, with artists creating temporary rooms and individually designed art suites that last about five months before returning to the river. Rooms run around -5°C, warmed by reindeer hides and expedition sleeping bags. The dining is part of the show too — an "ice menu" served on plates cut from river ice.

Over in Finnish Lapland, the Arctic SnowHotel in Rovaniemi has constructed a fresh hotel of snow and ice every year since 2008. Open from 15 December to the end of March, it has 20 rooms sleeping up to 70 guests, from double suites to family rooms for six. Meals arrive on ice plates at the Ice Restaurant, there's an Ice Chapel, and — the detail that sells it — a resident "Northern Lights Watcher" who alerts guests when the aurora appears.

Sorrisniva Igloo Hotel in Alta, Norway, claims the title of world's northernmost igloo hotel. It takes 250 tonnes of ice from the Sierravannet mountain lake and 7,000 cubic metres of snow to build it under a new theme each winter, welcoming guests from 20 December to late March. Alta is a strong aurora base, and the activity list covers snowmobiling on the Finnmark plateau, snowshoeing and husky sledging.

For skiers, Iglu-Dorf Zermatt sits at 2,700 metres on the slopes above Switzerland's car-free resort, open from 19 December to 4 April. Hand-carved igloos connect via snow corridors and hover around 0°C — noticeably milder than the Nordic options. The daytime terrace serves Swiss cheese fondue with hot and cold drinks. The same company also runs igloo villages in Davos, Gstaad, on Germany's Zugspitze and in Kühtai near Innsbruck.

Who is this actually for? Anyone who has done the usual winter-sun or city-break routine and wants a night or two of genuine novelty — ideally paired with a Northern Lights hunt or a ski trip. Most of these hotels work best as a one- or two-night experience within a longer Lapland or Alpine itinerary; the cold-sleeping rooms are the highlight, not somewhere you'd want to spend a week. Book early: with opening windows of just three to five months and limited rooms, the good dates go fast.
