Pros:
Hands down the most beautiful course I have ever played. It is nestled in the high Alps, right on the German/Austrian border. Views are beyond spectacular. Course is challenging, with significant elevation changes. The upkeep on this course is great too. There are stairs and wooden walkways throughout the woods to help traverse the more treacherous sections of alpine forest. The guy who works at the proshop is super nice and helpful. It's clear that the locals and course management take great pride in their course. The proshop/starter's shack has discs for sale and to rent (Latitude 64 mostly). The course has a good variety of left to right, right to left, uphill, downhill, wooded and open holes. For 14 holes, every hole is unique compared to the others.
Cons:
You will be doing a fair amount of hiking here. You descend about 1000 feet on the first 5 holes then ascend in the last 5 or 6. If you aren't in the best shape, like me, this will leave you a hot and sweaty mess. Also, they charge 8 Euros to play. That's steep, but it seems like they reinvest the money into the course, so that makes easier to rationalize for me. I bought a driver at the proshop as a souvenir, and they charged me half price for the round, which was cool. Another con is that this is a popular tourist area, and there are a good amount of disc golf noobies who play here becuase they are in the area for other activities and decide to try it out. I was stuck behind a group of 9 idiots playing together, chasing discs back and forth, not paying any attention to themselves and their beer. They didn't understand the concept of playing through, and my non-existant German didn't help. After that I passed at least 3 other similarly sized and experienced groups. According to a local, if you show up later in the day, this isn't an issue. Plus the sun sets so late here during the summer that you can start your round at 7 or 8pm and finish before sundown. So show up early or late to avoid the riff raff. Another con is there are only 14 holes. Technically I think it's 15 now, as they have 13 holes plus two alternates. My final issue here was that with all the elevation this course has, there is no rip it downhill, bomber hole. I think I through my driver full speed once maybe twice the whole round. This was disappointing as anytime I play a course in the mountains, I love the opportunity to throw a super long downhill drive. It helps reaffirm my masculinity. And Allgäu lacks this. Most downhill drives are touch shots with a putter, and the uphill shots are a little too short to unleash (and I don't consider myself a big arm player).
Other Thoughts:
This place is absolutely beautiful and every disc golfer should experience it. Teeing off from a wooden platform overlooking the snow capped alps and lush green valleys covered in wild flowers is unmatched anywhere else in the world. This course could easily be slightly redesigned and made into an 18 hole championship level, world class course. But disc golf isn't super popular here, and its amazing enough as is, so I don't expect any changes, and for me that's fine. Overall, for what this course is, it's pretty perfect. I'm only listing cons because the website asks for them. The cons seem pretty insignificant when your get to play disc golf in an alpine Shangri-la. This is definitely my favorite course in Germany and a MUST play for any disc golfer that comes within a few hour's drive of here.
