In reply to martinturner:
Just out of interest why Kvaløysletta? it's mainly residential suburbia.
I could be wrong, but I'm pretty sure there are camping restrictions for the three lakes above Kvaløysletta - they feed the water supply for Tromsø apparently.
Whilst you can get a bus from the Airport to Kvaløysletta, it's only about 40mins walking time. There are two supermarkets, a garage and two eating places (pizza / pasta and a thai takeaway), but other than that it's just housing.
If you went up Røtind, just a bit further West from where you're taking about, you'll get a cracking view over towards Store Blåmann etc
Whilst you do get a good view of Tromsø on the way down from the lakes, while you're up there it's just as Toby said, rolling moorland.
One other thing, you don't have to go out into the middle of nowhere to see the Northern lights in Tromsø, you can easily see them from the town centre.
