Central Park.

New York would be inconceivable without this 843-acre expanse of green delight. Pack a picnic (see V. Useful/Picnic Hamper) and head to Sheep Meadow in summer, a lovely stretch of lawn with tons of eye candy. For the best people-watching, you can’t beat the retro spectacle of the roller disco ‘funk circle’ / 72nd St / w/ends; or catch free shows of Shakespeare in the Park or SummerStage. Hire a row boat on the lake and grab a cocktail after at the Boathouse; take a group or private custom tour; or simply stroll around the reservoir for splendiforous midtown views / centralparknyc.org.
