The ice rooms at Icehotel are legendary. Many feature the artistic hand-carved themes that win each year's design competition. You’re really only expected to spend a night (maybe two) in them, though. The Warm Accommodations are a selection of more traditional hotel rooms or chalet apartments, all housed in permanent wooden structures. And then there’s the all-season Icehotel 365, whose solar-powered building stays cool enough to house permanent ice suites, as well as the Ice Bar.

We’re happy to report that this is exactly what you would hope a hotel called Treehotel would be. Just south of the Arctic Circle, in Swedish Lapland, a young couple took over a Thirties guest house, which travelers more or less ignored in favor of the single treehouse suite. So with the help of seven different Swedish architecture firms, they built eight more.

Suspended over a frozen river in the tiny village of Harads, Arctic Bath is unlike anywhere else: an architectural circle of timber enclosing an ice-cold plunge pool, with cabins tucked among the trees and out on the ice. The journey here is part of the adventure, but it is the stillness of the landscape that stays with you.

Umeå is not quite in Lapland, but it’s not too far either, and is worth a visit on your way up. The seafaring history of this university town is preserved in Stora Hotellet, a former sailor’s lodging that first opened in 1895 and is now a fine (and fun) boutique hotel that has turned the fantastic aspects of its heritage up to ten.

In the fishing village of Ballstad, midway through the Lofoten archipelago, Hattvika Lodge has converted traditional fisherman’s cottages into guest accommodations with mountain and sea access steps away. The property works directly with local fishers, ski touring guides, and sea kayak operators to arrange year-round activities, from winter aurora chases to summer midnight sun paddles.

On the southern coast of the Lofoten Islands, Nusfjord is among Norway’s oldest fishing villages, its harbor lined with red stilted “rorbuer” that once sheltered cod fishermen. Today, many of the cabins are reimagined as guest lodgings, where original timbers sit alongside understated contemporary design. A handful remain unchanged since the 1890s.

Even by Norwegian standards, Manshausen Island is out there. This island in the Steigen Archipelago was once a traders’ outpost, and the hotel’s 1880s-vintage main house is a relic of this era. But the sea cabins, as is evident from the photos, are quite a bit newer. These pared-down larchwood-and-glass structures perch right at the water’s edge.

Safe to say there’s nothing quite like the Kakslauttanen Arctic Resort, where you’ll sleep literally beneath the stars in an igloo made of glass — all so that you won’t miss a chance to see the Northern Lights. Most of the accommodations are actually log cabins with observation domes attached, for those who want slightly less exposure.

Deep in Finnish Lapland, the Arctic TreeHouse Hotel is nothing if not a winter wonderland — attractions include the Northern Lights in winter, midnight sun in summer, and its nearest neighbors put on dogsledding expeditions and reindeer drives. The hotel itself is a high-luxury, high-design experience; each “glasshouse” cabin comes with its own private sauna and immersive picture window.

There can’t be many hotels of any description much further north than VALO Ice Cube Villas, and certainly none more stylish. Here, in Finnish Lapland, 150 miles north of the Arctic Circle, stand four modern, cube-shaped villas, each one framing an impressive view of the landscape through panoramic windows. The interior style is Nordic modern-luxe, warmed by textures of wood, stone, and fur.
