Its a fantastic trip but weather can be fickle. Two years ago I had severe gales, torrential rain and 4 degrees C at the North Cape in July. After escaping, it was warm and sunny 70 miles south. I have friends who went in July last year and the weather was perfect, just like in the postcards. Campsites have wooden huts for hire with heating, beds cookers and utensils. I found everything worth exploring, except the touristy bit at North Cape. Having said that, had the weather been good I would have probably found it a wonderful place.
Scenery, wildlife, people....... I will do it all again one year...... wonderful. Personally, I found the Lofoten Islands to be the best and most spectacular part of the while trip. Have a great time. Oh and stick to the speed limit, fines are very high. Gill
