Over its 100-year history, the Mountain Play has primarily performed in the Sidney B. Cushing Memorial Amphitheater or the same clearing pre-stone seat installation.

However, since 2019, Mountain Play has been expanding its “off the mountain” offerings. In 2019, 2021, and 2022 Mountain Play produced or co-produced shows in The Barn Theater, home of the Ross Valley Players on the grounds of the Marin Art and Garden Center.
