Of all the places Eugene O'Neill– America's only Nobel Prize winning playwright–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. 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. Tour through Tao House and explore the grounds, but note you require an appointment to visit.
