## About Greenwell State Park

Greenwell State Park 25420 Rosedale Manor Lane Hollywood MD 20636Mailing Address: c/o Greenwell State Park 11175 Point Lookout Road Scotland, MD 20687 Greenwell is a 596-acre state park located on the Patuxent River in St. Mary's County, Maryland. In 1971, John Phillip Greenwell, Jr. and his sister, Mary Wallace Greenwell, donated their 166.6 acre farm to the state of Maryland for use as a public park for everyone. The state subsequently purchased the adjacent 430-acre Bond property and joined the two to form the existing park. The park is managed in partnership with the Greenwell Foundation, a non-profit organization dedicated to providing outdoor accessible recreation. The park has an honor system, with service charges ($3/ MD vehicles and $5/ out of state vehicles) benefiting the Greenwell Foundation to help operate the park.
