Norway is brilliant for cycle touring. It's a lovely country. I have been a dozen times, mostly for the winter ski touring but also rode from Kristiansand in the south along the coast to Bergen. This is a great route to cycle because there is a huge brand new dual carriageway that takes all the traffic and you ride along the old road, which is usually deserted and very pretty. Norwegian law allows you to camp anywhere not within 100 metres of a building or on cultivated land, it is called "Alleman's Recht" or something similar. Also the campsites are very civilised because the Norwegians expect everything to work (It's not like France). I suspect hotels are expensive.
It is a reasonable country to
live in - for instance, electricity is cheap, and supermarket food is slightly more than in France. Visitors might find it pricey, but then again it depends on what you buy. In the early days of Gordon Brown as chancellor the pound bought almost 14 Norwegian kroner but now you might get 9. Beer in bars is phenomenally expensive (see post above) but no one buys that - the licence to sell alcohol is very expensive indeed. Drinks stronger than beer must be bought from the state shop, and that might be 100 kilometres away for some people, so Norwegians rarely drink alcohol (and consequently have some of the lowest levels of cirrhosis of the liver and other alcohol-related diseases in Europe). Clever Brits take a couple of litres of Scotch in a couple of Sigg bottles and have a sip each night.
I used the guides produced by Castor, which are the best i have ever seen, anywhere, ever: laminated cards fit into a barbag mapcase and have all the info you need: campsites, shops, hotels, phone numbers, etc etc. I have Nordsjoruta Ost, Nordsjoruta Vest (two of these) and Setesdal og Hardanger. I am not sure if these can be bought any more EDIT - just checked and they available online and now cost a ridiculous $45 (dollars US). I think I paid less than £20. In fact I'd sell them to you if you wanted them - my plans mean i need a whole load of other maps now. I hope to ride from the bottom to the top of Norway summer 2016.
The weather is not that found in the south of Spain: then again it is not as bad as often made out.
Just about everyone speaks English - they watch UK television often, and in the winter often bet on the UK football (you can't play football in Norway in the winter because there tends to be too much snow) so it is not unusual to be in the middle of somewhere remote and to have a conversation in English about the fortunes of English football clubs. Certainly as far as communication is concerned, it is easier than France, and I speak (bad) French.
As for getting there - Norwegian Air won''t take a bike to Norway from Gatwick without a reinforced hard case (no cardboard boxes or plastic bags) and there are now no ferries. Best bet is easyJet (plastic bag for the bike) or BA. Ryanair flies to an airport it calls Oslo Torp, and is actually a three hour coach journey away from Oslo, but is a few kilometres from a cycle route from Oslo to Kristiansand. Unfortunately, although the destination is perfect for cycle touring, you do have to deal with Ryanair so i have never done it. YMMV.
Hope this helps.
