I've always been interested in Scandinavia and hope to visit when the kids are a bit older. If you like boreal forest they have quite a lot of it!
I also talk to radio hams over there quite often, usually on the radio, but also via Internet/ham radio links.
Anyway, I thought it would be interesting to try learning a bit of Swedish (which is apparently intelligible in Denmark and Norway, but not Finland or Iceland). There is a very good online course available free at:

In Iceland they speak a derivative of Old Norse, which is the language that was spoken in Norway when people arrived there. The two languages have become alienated thanks to danishification and swedishification of Norwegian while Icelandic was left untouched. Danish and Swedish had been a bit europified as well, if you know what I mean. This means all are slightly different, and Icelandic is rather more different, but you can get a rough idea if you read the text nice and slow. It's all linked in with Scandinavian history, which is worth knowing and illustrates the development of the languages very well. Finnish is a wholly different language, related to Sami and Hungarian.
I would recommend you learn Norwegian, which is kind of in the middle of Danish and Swedish, so you will understand each easily. There are plenty of teach yourself courses on Norwegian. It's how I learnt, and I know it very well now, though of course you can't replace going there and speaking it.
It's a comparatively easy language to learn as the grammatical structure is basically old English (which is where old english comes from...), but more complicated. The grammar is perhaps the hardest part, but it's a lovely language and will give you lots of insight into how Nowegian English is, which surprised me. Enjoy!
PS I'm dying to post a massive historical/linguistic lecture but I'd better not before you all fall asleep!
