I love to walk on 5th Avenue from 59th Street to the Metropolitan Museum of Art. It offers the very best of the city: tree-lined avenues along the west-side of the park, and beautiful New York architecture on the east side. I especially like the strolling on Sundays during the fall when the leaves are turning colors, or in the spring, just as the trees start to bloom. The walk is the perfect distance and ends in the perfect destination! You also pass the Frick and the Neue Galerie along the way, which are incredible buildings and other must-visit museums.
