Skied Keystone Jan 2013. I found this resort to be well organised and family friendly. The snow was excellent considering lack of recent snowfall but the high altitude kept it in pristine condition. As an advanced skier I was happy with the runs on offer and loved those long green/blue runs back to the village. Good on-mountain facilities available and lift queues pretty much non existent once on the mountain. Price wise, this resort is no different from any other big resort. Looking forward to going back again during 2016.
