Visitor Reviews of Blue Knob

Blue Knob is amazing as far as Pennsylvania can take it. Unlike other local resorts you can actually get some burn in your calves here. The Knob has some awesome glades and steeps (they had 2 small avalanches on some of the expert terrain, the last time I was there, since when do we get avalanches in PA?) and when it storms this place takes the cake. To my knowledge this place has the best and most varied terrain in PA. Blue Knob does not have much of a terrain park but the natural terrain will make up for that. Beware, this is PA and our weather usually sucks so this place is only really good when the weather is.
