Eugene O'Neill National Historic Site

America's only Nobel Prize-winning playwright, Eugene O'Neill, chose Northern California as his sanctuary at the pinnacle of his writing career. Secluded from the outside world within the serene walls of his Tao House, O'Neill crafted his final and most memorable masterpieces: The Iceman Cometh, Long Day's Journey Into Night, and A Moon for the Misbegotten.

About under an hour from San Francisco, 1.5 hours from San Jose and 2 hours from Sacramento by car.
