Harriman State Park is a vast protected landscape in southeastern New York, about 30 miles north of New York City, and one of the region’s chief outdoor recreation areas. Created after Mary Averell Harriman and her family helped block a proposed prison at Bear Mountain, the park was established in 1910 through a major land and money gift tied to further state investment. Roads soon improved access, and the park grew into a major getaway for city residents. Its more than 200 miles of trails, many lakes and ponds, and extensive facilities—many expanded during the Great Depression by the Civilian Conservation Corps—have made it one of New York’s most important preserves.
