Once again, CityListen is inviting you to celebrate Earth Day in the most visited city park in the United States. Central Park is the perfect place to celebrate Earth Day and gain an appreciation for nature and sustainability.

Central Park is one of our most popular tours in New York City. Can’t decide between Greenwich Village and Central Park? Or Broadway? Or Rock and Roll? Between now and April 30th, that decision just got easier. Buy any of these other NYC tours and Central Park is yours for free. Enjoy Central Park on Earth Day - and save the other tour for another beautiful day in New York.

While Central Park is almost entirely manmade and, in fact, stands as a monumental achievement in urban landscaping and design, the park is a sanctuary to millions of New Yorkers and an oasis of nature featuring a number of unique species of flora and fauna.
