To be fair… most of those sights are piles of mud with sign posts.

For tourists I’d rather recommend the cold war museum, the original Lego land, the beaches on the west coast, hiking along the east coast fjords, the lakes at Silkeborg, the desert at Skagen, the ruins at Kalø, the various nature reserves.

There’s plenty of stuff to see. May, June and August are the best times to visit. The rest of the year has unpredictable weather.
