Christmas lights and holiday activities are back this December, and that's just the beginning of all there is to see and do in Westchester and the Hudson Valley this month.

Westchester and the Hudson Valley are going all out for the holidays with the return of festive annual traditions such as The Great Holiday Train Show, Irvington's Hanukkah Village, and Watt Christmas Wonderland. New events include Legoland New York's Holiday Bricktacular and a Snow Ball with the Snow Sisters where kids can party with all the characters from Frozen. All are invited to celebrate Hanukkah at Ridge Hill's Menorah Lighting and Gelt Drop. And don't miss Santa's sensational helicopter arrival at Museum Village.
