Logically, you also have the best view from the highest point far and wide. If, yes, if it weren't for the problem with the fog. There was a year when the highest peak of the Harz was covered in fog for a whole 330 days. Not least because of his foggy days, even Heinrich Heine was accused of the following sentence: "Many stones, tired legs, no prospects, Heinrich Heine". We too have only been lucky with the view once so far, although there have already been ten ascents.
However, if you catch one of the few days with a clear view, you can see 163 kilometers from the Brocken plateau to the Kahler Asten (NRW). From the outside, the Brocken is quite round at 1,141 meters, with a radio tower and a radar dome on top - one reason why you can recognize it immediately from many vantage points in the Harz Mountains.
It is said about the Brocken that an Icelandic or alpine climate prevails here due to its exposed location. Without a doubt, it is a place of extreme weather conditions, comparable to an alpine peak around 2,000 meters. As a result, you always have to reckon with short-term onsets of winter, except in the midsummer months. So: It's usually cold on the Brocken. Or foggy. Or both. So be sure to bring warm clothes.
If you can only manage one route, you can take the famous Harz narrow-gauge railway back (to Schierke, Drei Annen Hohne, Wernigerode). The most beautiful ascent leads up from Ilsenburg via the Heinrich-Heine-Weg, the most demanding from Schierke via the Eckerlochstieg and the easiest from Torfhaus via the Goetheweg.
