This is one of the sites that you just visit to tick them off, but then turn out to be quite pleasant. I'm not really an expert in technical matters, but the importance of this station in the early days of radio technology was well presented in a guided tour, a movie, and a small exposition (there is a brand new visitor centre with a café). After the tour, you can explore the site on your own, and there is a trail with informative signs leading to the massive antennae. It should be noted that even though the site is called Varberg Radio Station, it is actually located in the village of Grimeton, easily 12 km away. There are occasional buses, but since I had to rush to catch one of the 2 daily tours in English, I took a taxi. It is also recommended to spend some time in Varberg, a pretty seaside resort with an impressive castle and a quite un-Scandinavian beach ambience.
