The park lies in the San Francisco Bay Area and is operated by the Midpeninsula Regional Open Space District. It offers approximately of hiking and equestrian trails and is dog-friendly. The Schilling Lake Trail leads to Schilling Lake, a protected wildlife habitat.

The Sierra Club donated this land to the Midpeninsula Regional Open Space District in 1978, after brief management of its old estate. The name Thornewood comes from Julian and Edna Thorne, who developed the land in the 1920s. The Thornes built a house designed by Gardner Daily and surrounded it with extensive gardens. Those gardens included Schilling Lake, named after the nearby August Schilling land. The Thorne and Schilling estates were both part of Rancho Cañada de Raymundo in old California.
Second-growth redwood trees grow in portions of Thornewood Open Space Preserve, especially by the lake. There are false brome grasses throughout the area.
