In reply to Kipper-Phil Smith:
Midges are not a problem. Too windy for 'em
.
Horse flies and sand flies can be a nuisance, though.
But generally speakin' Lofoten ain't bad at all in July nor August.
Oh, as for wild camping... Kalle is a good place to camp (water tap + loo), and you can get showers at the nearby camping ground for a few NOK (I think it was Sandvika camping, or the one before it on the same road... just ask at the reception... Oh, and it was cheaper than at Klättre Cafe, the shower I mean).
