The Home of Playwright Eugene O'Neill
Tours will NOT be offered on the following dates in September, due to the Eugene O'Neill Festival: September 5th, 6th, 11th, 12th, 13th, and 14th. Thank you for your understanding.
Of all the places Eugene O'Neill called home during his restless life, Tao (pronounced "Dow") House was the one that held him longest, the refuge where he wrote his last plays. In early 1937, he and Carlotta were living in a San Francisco Hotel. "No roots. No home," Carlotta wrote as they searched for a place to live. Drawn to the privacy and climate of the San Ramon Valley, they purchased a 158-acre ranch near Danville and planned what O'Neill hoped would be his "final home and harbor."
The Eugene O'Neill National Historic Site is part of a private, gated community. No personal vehicles are allowed to enter the community or main park site. A complimentary shuttle is provided to this free site and can be boarded at specific times in the town of Danville, California. Please follow the link, above or see our "Operating Hours and Seasons" page to learn more about making your reservation.
