many trails, interesting glades, large lift capacity
high price, relatively crowded slopes, catwalks
Sunday River is a good place to ski, but you will be sharing the experience with many, many of your new friends. Since it is a large ski area with a huge lateral distance and only a moderate vertical, you end up doing a lot of skiing on traverses and catwalks. It reminds me of Vail in this respect.
The glades are a lot of fun, but since many of your new friends want to ski them as well, they seem to get skied out pretty quickly. There are a number of really nice glades and they tend to be relatively less skied than the trails.
If you like groomed cruisers, this would be an ideal place for you, as there is a large variety of this kind of skiing. There seems to be a lot of lift capacity, so the lines were short while I was there. The downside to this large lift capacity is an increased number of skiers on the trails.
The general ambiance seems to be more oriented toward visitors from out-of-state than a place like Saddleback, or even Sugarloaf. It you want the low key Maine skiing experience, then this is probably not the place to go.
The views from the top are still spectacular. At $89, it seems high priced, but there seemed to be no shortage of people skiing there who were willing to pay. Although, in my opinion, while not the best in Maine, a trip to Sunday River is still an experience worth having. I am glad that I went.
