Events at the Park

​​ ​​​ ​

Located in the Appalachian Mountains, Greenbrier State Park is a multi-use park providing many kinds of recreation. The 42-acre man-made freshwater lake and white sandy beach draw many visitors who enjoy swimming, canoeing, boating and fishing. A visitor center is open year-round and features information on the South Mountain Recreation Area and a small gift shop.

Almost eleven miles of hiking trails meander through a variety of wildlife habitats. Rock outcrops show much of the earth's geologic history. A portion of the Appalachian Trail enters the eastern edge of the park on Bartman's Hill Trail.

Greenbrier State Park offers 164 campsites in a forest setting with fresh water and bathhouses in each camp loop. Suited for a variety of campers, the park offers two pet-friendly camping loops, one electric camping loop and tent and RV sites.

Greenbrier State Park offers an accessible visitor center, picnic areas and some campsites. A beach wheelchair is also available. For additional accessible amenities in Maryland State Forests and Parks, visit the Accessibility For All section of this website.​​​​​​​​​​​
