Wow! I can't believe this hasn't been listed! A must for anyone who has anything to do with or likes German culture, or just likes beer! I will do my best to describe this unique and highly popular event, but I doubt I will do it justice.
Held the last Saturday in June, July, and August, German Park is a traditional German festival atmosphere. Live German bands play near the dance floor, traditional German food is served, and it's hard to miss the smells! German beer flows, and you by it by the bucket, yes the bucket, which you may keep. The party goes until the beer runs but for the most part, there is a closing time but I don't remember what it is. Arrive early! the later you wait to arrive the longer the lines will be to park, get in, and for beer. Also they will stop serving food so if you go for the food go before 7pm.
There is no better atmosphere in Ann Arbor, entire families attend, children too, and even if you don't like German food or music you will still enjoy yourself drinking and people watching. This is outdoors, in a parklike setting so prepare yourself for the weather, and bugs! There are an abundance of picnic tables but I have seen table space run out, this is that fabulous. Entrance fee used to be $5 that may have changed since the last time I was there. Beer and food are very reasonably priced.
