In reply to J1234:
I had a fantastic family holiday in Norway combined with the Lofoten, although was many years ago and didn't involve making use of the climbing at the time. There is stuff to do on and around Lofoten for families, including the de rigeur whale watching trips and some great family friendly campsites (or at least ours was). We combined with a driving holiday around Norway (although appreciate that's not everyone's bag) - quite easy if you're willing to take a few days out to combine with time down in the fjords, and the trip up/down include crossing the arctic circle which is diverting for kids...
