On the other hand there are many nice places around the valley. I think that's the only thing I miss from the valley, drive 40 min in any direction and you're either in a forest, a desert, on top of a mountain or at a sea side. I live in berlin now and it's quite the opposite, the city if full of life but the nature sucks for a good 200km radius.
I also remember remote hiking trails going up the hills south of mountain view but I can't place them on the map. They were always empty, best place to chill and get out of the stressful environment.
To be fair, 200km - which is quite a distance for a small country like Germany - around Berlin includes a LOT of nice nature areas, e.g.:
Baltic Sea, Mecklenburg Lake Plateau, Saxon Switzerland, Harz, and many more.
