Just outside of Saariselkä is a world-famous wilderness resort, who's central feature is two clusters of glass igloos. These surprisingly comfortable 'pods' have the single purpose of letting you spend the night under the northern lights. All you have to do is lie back and think of Lapland as the aurora borealis work their magic across the sky. But only is the solar winds are blowing and it's a cloudless night. If not....well, it was an experience and at least you tried!
The igloos have comfortable twin beds (can accommodate maximum of three, with camp bed added), a small en suite toilet and are plenty warm due to the thermal glass, which also maintains the clarity and does not allow the snow to settle on top. The reason you are out here is because a) this Eastern region of Lapland has an outstanding success rate - if you are going to see the Northern Lights anywhere, then it is here - and b) the resort is well away from all light pollution.
The excursion out to Kakslauttannen (for that's where they are) includes transfers, a three-course dinner & breakfast, use of the sauna and, of course, the night in the igloo. If you simply want to head out to visit the resort, but without the overnight, then this can also be arranged.
You must pre-book this excursion, as Kakslauttannen is a very popular resort in it's own right - many fly all the way from Asia just for a couple of nights here. It is unlikely to be available to book locally.
