This is our second year visiting Park City and the Olympic Park is by far our favorite family activity.
We've only visited in the summer and there are always young ski jumpers going down the practice ramps into the large pool. In addition Olympic teams are often training there and the jumps they do are spectacular.
If you are more of a doer than a watcher then for $95 you can take a three hour lesson that culminates in going down a smaller ramp. My son dis this and had a blast as the staff was fanastic.
In addition there are alpine slides and zip lines but we have not. Tried those yet.
Great and entertaining place!
