Great news - following the new partership with Vail, the Kirkwood Network Season Pass is back for the 2012/2013 season. The pass this year is a simple, 100% unlimited season pass to Kirkwood Mountain Resort (exclusive to Kirwood). The initial pass price is $329 and will increase fairly soon, though exact date is not yet set.
