Pretty big, even at 50% open!
Can't compare to real mountains, but best in the west
Our family trip this year for Christmas time was a long weekend at Granite Peak in WI. All in all a great time, a little icy, but that was expected. It was pretty early in the season, so not much was open, but surprisingly there was enough open and the trails were pretty long and fun.
The area around the mountain is pretty decent, some good restaurants and the downtown area is a lot of fun to walk around.
Prices weren't bad since we got a special deal on them, but at full price they may be a little much.
I highly recommend taking a trip out there though, some condos right at the base were a great choice since we had a lot of room and could walk to the lifts!
