Arrive in town, drop off my stuff. I booked the hotel based on price and availability, I stayed at the Gastof Fraundorfer Hotel in Partenkirchen.
Head to the railroad station and buy a ticket on the Zugspitzbahn up to the top. As you can read below, there are 2 ways to get up to the top – cogwheel train all the way, or part train and part cablecar. The train takes about 15-20 minutes longer but you’re climbing up and through the mountain (with stops so you can get out and look around), while the cablecar should have some great mountain views. I took the train both ways, I don’t know if you can do one of each. Made it back down about 1800.
Up top at the Zugspitze are some AMAZING views of the mountains. There’s a restaurant at 2600 meters, great place to have a beer and just relax. Then there’s a cablecar that takes you up even higher. You’ll probably have a lot of sunlight, by mid-October the sun was going behind the mountains at 1615.
Had a beer & apple crumble torte at Sonn Alpin (2600m, 8530 ft), summit at 2962m, 9618 ft. Surprisingly, it got warmer in the mountains - it was 3 deg (37F) when I left Munich at 7:45, 4 deg (39F) in Garmisch at 11am, and 9 (48F) at Zugspitzplatt at 2pm.
Back at the bottom, I wanted to go to the Tourist Information booth, but I didn’t get there in time, so I had a nice little wander in that general direction (see the Banhof in the center, the TI at the upper left, and the hotel at the upper right: https://goo.gl/maps/u9ayPR93g6G2 )
After I came back from the mountain, I strolled around the town before I decided I was hungry and wanted dinner. I stopped at Pizzeria da Renzo in Partenkirchen, a few blocks from the hotel. Nothing special, I was just in the mood for pizza.
Turns out the hotel has a recommended restaurant (I didn’t notice it when I checked in, and didn’t check for any recommendations). Later that night I came down for a beer there was a party going on. I posted a photo with the caption “Sitting in the lobby restaurant of my hotel in Partenkirchen, in Bavaria (with a half liter of Paulaner). There are men in lederhosen and women in dirndls, and a guy playing the accordion. And in my booth are signed pictures on the wall by astronauts Jim Newman and Ox van Hoften.” TJ Creamer commented “Been there... didn't sign! Congrats! GREAT atmosphere and exposure... Was kann ich jetzt sagen, aber: SUPER Gemuetlichkeit!”
