Pros:
Challenging course with water and some obstacles. Most of the holes are well designed and vary. The location is nice and the flow is pretty good. Many Tees are on the concrete paths. The parking-lot is huge and right next to the course.
Cons:
On a sunny summerday this course is unplayable because of other people using the park for recreation and walking.
Some doglegs are unnecessary/boring.
Some holes are way to muddy as well as some tees. Some holes are a bit unfair with trees in addition to water.
Other Thoughts:
There are many things to do at the Revierpark Wischlingen lika a brine bath, Mini-Golf pedestrian walks and some playgrounds. Therefore many people visit the park and make it hard/unable to play all holes.
All in all a decent basic course.
