Pros: Grooming, Accessibility, Terrain Variety, Lifts
Cons: Crowds, Price
I have stayed right at Loon a couple times and have been very satisfied with the experience, it is a bit pricier than some other areas with comparable terrain, but I still enjoy the area a lot. The mountain has a nice variety in terrain and is laid out in a manner that you can avoid crowds if you figure it out. The North Peak is good for avoiding crowds and has the best terrain in my opinion. There is an unadvertised pull off into the woods on the North Peak as well that goes to a bird sanctuary about 100 yards off the trail where there is a natural bench made from a tree and with some bread will attract hundreds of birds. You ski in and out into the woods and back on to the trail.
They do a good job at grooming and seem to keep the mountain in good shape with only a handful of trails icing over come the end of the day. The recent addition of the South Peak has been great as well. The lift service is superb as well. They have High Speed Lifts and a four person Gondola that serve most of the mountain. It is also extremely accessible being right off the Kancamagus Highway. This leads to the crowds, but does make it convenient. The issue with that is that the lift line for the Gondola and Kancamagus Quad can be lengthy during peak season. This is easy to avoid by skiing on the less accessed South and North Peaks.
The mountain is not far from the town of Lincoln which has some very good restaurants and shops. Loon has nice slope side accommodations across the street at the Village of Loon; on the mountain; as well as at the new South Peak resort. They have a convenient shuttle service as well.
