Palisades Park

New Yorkers make the pilgrimage across the George Washington bridge into the New Jersey Palisades for this 24-hour spa, and with good reason: With several floors offering a variety of spa and sauna options, from men- and women-only whirlpools, to a traditional Korean Hwangtoh (yellow mud) Room, to an infrared sauna accommodating several people at a time, it’s the mother of all spa complexes. The Korean noodle bar and over-the-top kitschy decor—fake palms included—are the icing on the cake.
