Encompassing a range of the Karwendel limestone Alps that straddles both Germany and Austria, the Karwendel Nature Reserve is a must if you find yourself traveling through southern Germany. An hour and a half drive south from Munich, you'll be struck by how epic these mountains are as they provide the backdrop to Lake Walchensee, with dozens upon dozens of stunning, snow-capped peaks that break the 2,000 meter (over 6,500 foot) mark.
The charming town of Mittenwald makes a great base of affairs from which you may access the many hiking and skiing opportunities of the area, as well as a cable car (the Karwendelbahn ) that will bring you to a mountain-top restaurant, a giant telescope, and deeper access to this incredible wilderness.
Although most of this range lies in Austria, there are still plenty of things to do on the German side, including a medley of biking and hiking trails along the alpine Lake Sylvenstein, which also concedes some excellent photo opportunities. For those just looking for day hikes, opportunities abound near Mittenwald will do the trick. Then again, via ferrata may be the most heart-pounding and satisfying avenue in which to enjoy this spectacular landscape; the Mittenwalder Trail undoubtedly provides your fix for that. If you're looking to push yourself even further, you could wake up in Karwendel and find yourself in the Austrian Alps by lunchtime. If that won't appease your adventurous spirit, then nothing will!
