The best place in NYC for a calm and relaxing walk is Central Park. While entrances to Central Park around Columbus Circle can get crowded, I recommend entering the central park through the upper east side. Taking the subway to 79th Street will get you very close to some of the most scenic areas of the park
Central park Zoo is definately a must see and my favorite is the South Street Seaport. You can also eat really well in little Italy and China town. Times spaure is a mad house but lots of fun. FAO schwartz toystore is great if you have kids, with a ferris wheel inside the store
New york city in United states of America is a great city for watching interesting area like river side pathway.Riverside pathway is always calm for walking or sitting beside river.Another scenic area is center of town where stood high rise building.skyskreper like united nation building and new a new building where was world trade center building.
