Palmer State Park is a public recreation area covering over 555 acres of scenic woodlands along Deer Creek in Harford County. The park, which remains largely undeveloped, offers visitors the opportunity to enjoy nature through activities such as hiking, fishing, and bird watching.

The main feature of Palmer State Park is its riparian environment along Deer Creek that supports diverse wildlife habitats. Opened for public use on an informal basis without any set date or grand opening event due to its natural state development approach; it provides rustic outdoor experiences rather than modern facilities. Trails meander through mature forests.
