"In 1936 a marvelous opera house was built on the site of an old deer run in the forest above the village of Harrison. Constructed of rose hemlock in the Adirondack Style with hand carved fixtures and near perfect acoustics, the 300 seat theatre was considered as fine as any on Broadway. Now listed on the National Registry of Historic Places, Deertrees is operated as a non-profit theatre and presents an eclectic offering of theatrical productions and comedies, family entertainments, and a variety of musical concerts during a season that runs from late June until early September." Most shows take place Thursday-Sunday, June - Labor Day.
