This is what I suggest
: As a fellow Pennsylvanian - This has been my experience, If you are truly looking for the best places to ski in PA. 7 springs is the best resort close to State College. After that it is ELK hands down. Why? not because the terrain is better or steeper etc. let's face it the limiting factor here in PA is snow conditions. If there is any decent snow in PA it is either gonna be in the West near 7 springs or at Elk which is so remote and far north that you get no heat bubble effect from near by towns etc. Like - PA ridge racer said, It can be a ...dog to get to during the winter. I skied there three times, every time I have gone it was dumping and the access roads from Rt 81 to the hill were snow covered and barely plowed. What a Blast!! - but be careful, go slow because the road is a real small sunken, twisty thing that likes to eat cars. Listen Blue is a great little mt. - cool runs like sidwinder (even though they turned the thing into a stinkin circus), one or two steeps and nice bumbs on mainstreet. But unless there has been a nice long cold spell or a recent dump, their snow is gonna be crap. They are farther southeast than the other resorts mentioned here and there man made snow quality just never seems to be that good. Don't get me wrong I go their alot but for the drive you are making I think it would worth the extra time.
If you want a cool little weekend trip here is my suggestion. Drive up to Scranton Stay at one of the hotels in the city or near Montage (The station is real nice in Scranton - a radison hotel or there is a mariot Courtyard at the base of Montage Mt.) Then you will have some bars etc. at night. Hit Montage one day and hit Elk the next. Elk is probably 35min drive North on Rt 81 from Scranton, and Montage is probably 10 min drive from downtown. That way you won't get sick of one or the other, and you won't have to worry if the weather is bad (Elks access road). Though I would go for it if you have a 4X4. Montage has a real nice group of advanced slopes at the bottom of the Mt. with their own lift. It is a real nice set up because it keeps alot of the slower skiers off the faster slopes which makes everyone safer. Think Snow!
