Recipients of TripAdvisor's certificate of excellence in 2012, NYC GoGreen Tours keep themselves carbon-neutral chiefly by sticking to the favored transportation of native New Yorkers: walking. Their catalog of New York walking tours gives patrons a detailed look of the city that's difficult to get from riding on a bus or the roof of a subway car. Each jaunt focuses on one neighborhood or attraction, whether it's Central Park, Harlem, or downtown. Guides toss an entertaining stream of history and trivia over their shoulders as they lead their groups, pointing out remarkable landmarks.
The company also hops onto eco-friendly wheels to lead bike tours and pedicab tours. Flocks of bikes ride through lower Manhattan, beneath the Brooklyn Bridge, and Central Park, or patrons can sit back in a pedicab carriage while their guide cycles through Chinatown and Gramercy Park.
