Spread across 50 acres of virgin forest (just north of the Bronx Zoo), the New York Botanical Garden (opened in 1891) is home to several beautiful gardens and the restored Enid A Haupt Conservatory, a grand, Victorian iron-and-glass edifice that is a New York landmark. You can also stroll through an outdoor rose garden just next to the conservatory, and a rock garden with a multi-tiered waterfall. It’s possible to take the subway via the B or D line to Bedford Park Blvd, then take bus Bx26 east, but it’s easier to take the Metro-North’s Harlem Line from Grand Central Terminal to the Botanical Garden stop (one way off-peak/peak $5.25/7).
