Hickory Hills Disc Golf
In the summer: A huge disc golf course operated by the City of Traverse City. In the winter: a low budget but quality ski hill owned and operated by the City (your host learned to ski here and came just about every day in the winter).
Connected to my property, but it's a steep up hill to get there from here. Park at the red barn and walk from there if you don't want to start going straight up hill.
