The Stern Grove Festival is an admission-free series of performing arts events held during the summer months in San Francisco. Established in 1938, the festival is held at Sigmund Stern Grove, a eucalyptus-wooded natural amphitheater on a 33-acre (130,000-square-meter) site about two miles (three kilometers) south of Golden Gate Park that ranges from 19th Avenue and Sloat Boulevard west to 34th Avenue. This festival went on hiatus in 1942–45 due to World War II and in 2020 due to COVID-19.
