We travelled by car, due to the travel flexibility it offers - the journey to Norway from Slovakia is about 1 400km long and its almost all highway type. The we took a ferry from Hirsthal (Denmark) to Kristiansand (Norway), it is 4 hours and 15 minutes.
Norway is a country which is quite expensive for travelling - especially fuel, food and accomodation, which are the most important things for a traveller. If you want to stay on the "budget line" consider camping and your own supplies like we did. Campings are usually very good equipted and at that time of the year not much crowded.
From the sightseeings I would mention: Preikestolen in Lysefjord - the fjord overhanding cliff where you can stand as a priest and the tell the world the "whole truth". There is a track which takes about 1 hour and 45 mins, sometimes quite steepy; The Kjeasen farm close to Eidfjord - was described as the most remote place in Norway. There is a 1,8km tunnel leading to it, cut into pure rock. Go via it back as a last one, stop, turn off the headlights and enjoy... :-() Lovely view over the fjord and a few sheep around...

Jostendalsbreen with its glaciers is definitely a must see, but be aware of roaming Japanese tourists - they frequently visit this place. Geiranger fjord - one of the most picturesque fjors is beautiful. The are two ways to get there: road and ferry. The road is closed during the winter, so check the tourist information ahead. The ferry offers 2 in 1 package: you get a ferry to Geiranger and also the sightseening trip, which you would probably when you get to there by the road. In general all the points which are highlighted on the map are definitely worth seeing.

If you plan to see something different during your summer holidays, then Norway is a recommended destination.
