Only a two-hour train ride north of the Big Apple, the Hudson Valley and nearby Catskills will make you feel like you've travelled half a world away. Famed for its sustainable farm-to-table fare, the valley is a spectacular place to enjoy world-class dining, museums, and jaw-dropping views (especially in the Fall). Get pampered at a spa resort, or for a more nature-immersive experience, a rustic cabin is the way to go.
