Wave Hill, New York, New York
Soul-filling views across the Hudson River to the forested cliffs of the New Jersey Palisades make this a blissful haven amid New York City's bustle. The 28-acre property includes two former "country estate" mansions and an urban woodland. Washes of color from the many flower beds stand out dramatically against green lawns, trees, and shrubs. Everything builds to a peak in autumn, when the plantings are designed to take full advantage of the Palisades' fall foliage in the background; 718/549-3200 or wavehill.org.
