Visitor Reviews of Chestnut Mountain

I was at Chestnut Mountain just once. It was the only resort I had close enough from work (Lena, IL). I ski there last Dec. 2nd 2008, and got the early season special "the date is the price" so I ski for $2 (cheapest I ever had). First thing I can say is that the views of the Mississipi river are just amazing. With a nice ski rental service and good lifts you can enjoy of the resort with no complain. The runs are short but, in some of the cases, real black ones. So even though it is a little resort, the well prepared runs have 100% snow making and lights. I could say it is a nice place to stop by if you are in the area, you'll get surprised.
