The Hickory Hills course in Traverse City, Michigan is a ski/sledding hill course. So you will throw a lot up or down but not a lot flat.
It is always useful to have a local guide to learn a new course so make new friends in the parking lot if you can.
Hickory Hills is a fine and challenging course. I don't recall any water but I am old and my memory is suspect. It is easy to miss the line throwing downhill and shank into the woods. If you have little practice throwing up or down steep hills it is much harder than it looks.
Yeah take a guide for sure. Bring some hiking shoes or boots. Lots of elevation and plenty of woods. Some of the pads are short. Just like Mark said its like playing on a ski hill. I also do not remember there being any water. But I do remember a lot of hills. You could throw a disc and miss and it could roll down a hill for days. There is one throw that is SO FREAKING AMAZING! You throw down a ski hill, over 1000 feet with a beautiful view of Traverse City and the bay. Bring sun tan lotion and plenty of bug spray.
