Condé Nast likes Cold Spring:
"A short jaunt on the Metro North from New York City, these two little towns have become popular in spring, summer, and fall. They're beautiful, with DIA: Beacon the star around which a constellation of eating, drinking, and hotel options have sprung up. Since they're a quick car or train ride apart, you could see both in one day, if you like. Consider steak frites, ice cream by the water, drinks overlooking a rumbling waterfall, and a quaint B&B if you can't bear to leave so quickly."
