Breathtaking lake, even more beautiful than the Konigssee, if it's possible. I highly recommend the…read moreboat trip out to the Obersee. You'll need to allot time for a short hike around the area. I truly haven't been a part of scenery as spectacular as this little corner of Germany-Austria. The sun! The shining green lake! The mountains! Holy hell, if this place doesn't do it for you, I don't know what will. Close your eyes, take a deep breath and feel it. The spirituality of the alps. Unforested, unsettled and so pristine. If you're lucky you'll catch a glimpse of the Alpine cow. Amazing!
