Gore is the best place to ski in NY. They mostly corrected all the old traverse issues when they replaced the gondola and added a new chair, then they added some new traverses when they expanded last year. The new chair keeps traffic off the upper mountain, so it's all good. Gore also has more tree skiing than Whiteface, and it has one of the steepest trails in the East.
There's not much to do off the mountain, but there's a few nice hotels that stay open in the winter.
Hickory Hill is going to reopen this year, so I'm looking forward to the best season in years in the Adirondacks.
