Hi Soar!!!
norwayfan is right! you can't miss the fjords and once u are there u should try to do some trekking. There are tons of things to do in Norway, fishing, hiking, safaris... When are you planning to go?? and are you going solo traveling?? if you are planning to go by yourself, then u might be interested on the "Norway. Your Way" competition, but that's on August, not July.
One of my recommendations is to stay on a fisher mans cabin, and also to visit Drøbak, Santa Claus home

is soooo pretty!!!
Hope you have looots of fun! Norway is really wonderful!
