I have visited Yonkers, NY on numerous occasions. I live north of Yonkers, and I regularly stop to explore this city while I take the train ride towards New York City. In fact, Yonkers has four train stations along the Metro North Hudson Line, which leads directly to NYC's Grand Central Terminal. The train ride from Yonkers to midtown Manhattan is only about 30 minutes.
I get off at the Glenwood station, which is within walking distance from the Hudson River Museum in Yonkers. I enjoy the museum's collection of fine art, particularly the paintings from renowned painters of the Hudson River School 19th century era. Then I head to the waterfront John F. Kennedy Marina Picnic, a park that's right behind the museum. I enjoy the scenic views of the Hudson River and New Jersey's Palisades Cliffs, located across the river. Yonkers is very densely populated, with a mix of single family homes, apartments, and multi-family housing. There is little space between many of the homes, even in the most isolated and quiet neighborhoods. The city is clearly dominated by an urban character.
Currently, Yonkers is undergoing a major revitalization project in the downtown area, and I can't wait to revisit this city and explore the new restaurants, businesses, and shops. I also heard of plans about a renovated waterfront promenade.
