In reply to butlinpm: i went end of july/august...loads of mossies, but thats part of the fun. i walked from kvikkock north through rapa valley then north to akka range. then cut back down padjelanta trail on the west then crossed sarek again from west to saltoluokta in the east. it is wild indeed but truly awesome. many mountains to be climbed or walked up too.
to get to kvikkjock was a flight to stockholm then 14 hours on train north, then a few hours on a bus...but all very do'able
you've got to be up for walking through cold rivers, plus a distinct lack of paths...but if you are you will love it
