Is there anywhere in Varmland that you'd particularly recommend? I'd love somewhere remote and forested with sort of lakes to explore and stuff, but then, not too many portages either
And wildlife!
Northern Värmland is less densely populated, while the area around the Dalsland-Värmland border (where Preben is based) is more of the "hundreds of lakes, all more or less interconnected" style of landscape. If you want to battle Swedish have a look at

As to remote; what is your defintion of "remote". Compared to e.g. Holland or Suffolk it is all howling wilderness, compared to the Yukon or Nunavat it is all pretty suburban. If
I wanted to be away from people for a few weeks it is not where I would go; you can find spots no one will come for weeks on end if you are off season, but for any travel you are bound to see Man and his works.
As to protages; get a canoe cart when you rent your canoe. In that region there is a lot of small dirt roads, and with a canoe cart you can portage for many km in relative ease. I like the "Nordmarksvagnen" that Preben at least used to rent and sell, since it has larger wheels and thus makes less than perfect roads easy.
Suggestion; buy a large scale map (say 1:300000) of the region and have a look. This is lousy for navigation, but ideal for seeing what kind of landscape you are dealing with, how far from communities you are, etc. Or surf Google Earth.
