Hiking nearish to Munich besides Zugspitze?

There are many different trails in the area surrounding Garmisch-Partenkirchen. Why only consider the Zugspitze? There are even some trail books published for this area.

Google 'Münchner Hausberge' - literally translated, that means 'Munich's local mountains'. You'll find one-quarter of Munich's residents there on weekends, which is why it's called that, not because it's the small mountain in the Olympic Park :-)

For example, that would be what Wikipedia is mentioning:

Mangfallgebirge, e.g. Plankenstein
Ammergauer Alpen, e.g. Ettaler Mandl
Karwendel, e.g. Lamsenspitze
Rofan, e.g. Guffert
Chiemgauer Alpen, e.g. Kampenwand
Wettersteingebirge, e.g. Alpspitze

And the Wiki explanation for 'Münchner Hausberge': The Munich Hausberge is a loose group of mountains within the Northern Limestone Alps, which are characterized by being accessible from the city of Munich as a day trip for mountain tours or similar alpine sports such as climbing tours or ski tours.

Thanks, Mignon, for the tip. The Hausberge look wonderful. I'm seeking, though, a spot a longer drive from Munich so that one quarter of the city's population isn't there with me on the weekend! :)

Maybe, for example, the Pitztal Valley?

Of course, I was just kidding that soooo many Munich residents are there :-) Whenever a cable car goes up, there are a lot of people. But if you can only get to the summit on foot, then there are significantly fewer people doing that. But it's true, anywhere that's easy to get to by train can be busier on weekends. During the week, it seems much more relaxed.

I've never been to the Pitztal. The almost pleasant problem you are facing now is that you have so much choice.

King Ludwig II's 'Schachenhaus' has recently been declared a UNESCO World Heritage Site. You can only access it on foot, and I think the hike is fantastic, as you first walk through the Partnach Gorge. Of course, other people hike there too but not too many because it is not a Sunday stroll. At least you can say that you visited something of King Ludwig that I think is even cooler than Neuschwanstein.

Was in the Pitztal, Österreich late in the ski season in March a few years ago. Other than skiing there was not much going on. We did take the Gletscherexpress to the top. That year the Föhn wind had brought in so much Sahara dust that the snow was orange. I remember helicopters dropping charges on the hills to prevent avalanches. Just got back from the Ötztal. That was a nice trip. Took the Bergbahnen Sölden up to the Elements Restaurant. Stayed in the small village of Gries. Drove the toll road Ötztalstrasse into Italy, but turned around after the street got too narrow and not too much fun anymore.

Anyone have suggestions of hikes to look at or parts of the nearby
Alps to consider?
