Camp Ripan

Kakslauttanen Arctic Resort is Finland's original and most famous glass-igloo resort, in the Saariselka fells 250 kilometres north of the Arctic Circle, where thermal glass igloos let you watch the northern lights from bed. Around 214 accommodations spread across two villages, from classic glass igloos to Kelo-Glass Igloos that combine a log cabin with a glass-domed bedroom — private sauna, fireplace, kitchenette and full bath, sleeping up to six — and a 310-square-metre Luxury igloo for twelve. The world's largest smoke sauna holds 200, with Lappish dining, an aurora-alarm service and husky and reindeer safaris. The iconic bucket-list igloo stay; for the highest comfort, the Kelo-Glass tiers are the ones to book.

Arctic TreeHouse Hotel is a Scandinavian-design treehouse hotel on the Arctic Circle, next to SantaPark and within walking distance of Santa Claus Village — around 60 stilted timber suites, each built around a floor-to-ceiling panoramic window for northern-lights and forest views from bed. Cosy Nordic interiors and private decks run throughout, with the larger ArcticScene suites and two-bedroom GlassHouse chalets adding private saunas, fireplaces and room for families of up to six. Rakas Restaurant serves Lappish cooking, and husky rides and reindeer wait on the doorstep. Northern lights from your pillow, with Santa next door.

Arctic Bath is an architectural floating spa hotel on the Lule River at Harads in Swedish Lapland — a timber circle around an open-air, ice-cold plunge pool fed by the river, ringed by saunas, that floats in summer and freezes into the ice in winter. Just 12 glass-fronted cabins surround it: six cosy water cabins on the river and six two-storey land cabins for families, all heated with wood-burning stoves. A Member of Small Luxury Hotels of the World with one Michelin Key, it pairs the sauna-and-cold-dip ritual with Scandinavian set-menu dining and dog sledding under the northern lights. Design-led Arctic wellness.
