One of the best family mountains in the East, Butternut has been the bunny slope of choice for generations of New Yorkers and New Englanders. The mountain has a terrific ski school for the kids, plus adult lessons if you need to brush up on your techniques—or if you need to learn the basics. The First Timer Package includes a beginner lift ticket, rentals and a 90-minute lesson for just $85. The package is for skiers ages 4 and up—start 'em young, and your little skier will always be a natural on the slopes.
