What type of "hiking"? Walking or real hiking?
If by hiking you mean REAL country type stuff, get on the tube to the endhaltestelle in Botnang and there are enough woods there to keep you occupied all day. Some of it steep. Up to Schloss Solitude, beyond to Bärensee (a walk in itself) and you coud eventually walk all the way to Leonberg... And plenty of wildlife (which I can vouch for, a wild boar ran into my car near Schloss Solitude)
Depends how much time you want to spend in them there woods! The first time I did it, it was a bit like "Blair Witch Project".
Alternatively, hike to the Frühlingsfest with us on Saturday
