Not 100% sure where this should be posted since Silverton has a lift, but is really more of a BC experience.
Anyway, the 299.00 season pass is pretty attractive considering the total amount of ski-days this buys at Silverton and some of their partner resorts. If you're spending a week skiing in CO, this might make sense. Just bought the limited, 5 Sundays only, unguided pass for 69 bucks.
For 99.00 a day, the guided day seems like a good deal too considering the terrain, setting, etc. Vail for example goes for maybe 105+ per day or so, but you'd be skiing with thousands of other skiers.
Will try to reminder to post the result/impression at the end of the season (have not skied there, but friends have. Nothing but positive comments).
