Low lines, little ice, prices
value, lack of variety
Peak 'n Peak is an average resort. It only has 27 trails, so it isn't bad for a half day trip. I went last year, and we had went down all the runs in a few hours. I'm intermediate-advanced skier. I ended up going down the black diamonds for the rest of the day (which are a lot easier than other resorts). The lack of runs makes it get old too quick.
The prices are cheap for rentals and lift tickets, but compared to Holiday Valley or other NY resorts, it has a poor value.
If you are just starting out skiing, Peak 'n Peak would be a good place to start.
