First opened in 1891 and incorporating 50 acres of old-growth forest, the New York Botanical Garden is home to the restored Enid A Haupt Conservatory, a grand, Victorian iron-and-glass edifice that is now a New York landmark. See the website for a list of regular events, which include themed walking tours, children’s book readings and film screenings.
From mid-November to mid-January, hordes descend on the gardens for the annual Holiday Train Show in which model trains chug through elaborately built recreations of NYC landmarks built from plants! Even if the line through the show moves at a snail's pace, it's worth going at least once, especially if you have kids.
