Greenbrier State Park

Fall bench at Greenbrier State Park

Greenbrier is a multi-use park providing many kinds of recreation. The Appalachian Trail passes through the park. The 42-acre man-made lake and beach draw many visitors who enjoy swimming, canoeing, hiking, picnicking, fishing and hunting. A connector trail to The Appalachian Trail is located in the park. As with most of Maryland's State Parks, a park map is available at the park office.


Attention Greenbrier State Park Visitors: Due to unscheduled repair work on the dam, the Greenbrier Lake water level has been lowered by approximately 4 feet. The swimming area is significantly reduced in depth, but the beach remains open for wading only. The boat ramp is closed; however, kayaks, canoes and other small hand-launched vessels may be launched from the ramp or beach. Camping, picnicking, trails and shoreline fishing remain available. Park activities and programs remain unaffected throughout the summer. The reduced water level will last through the remainder of the year and until dam repairs are completed. Please check the department’s website (dnr.maryland.gov) and social media for updates. Thank you!

Located in the Appalachian Mountains, this state park offers many recreational opportunities. The man-made freshwater lake offers swimming, sunbathing, boating and fishing opportunities. There are also hiking trails which meander through a variety of wildlife habitats and afford a view of the area's geological history. Picnic tables and grills and playgrounds are available in the day-use area.

A portion of the Appalachian Trail enters the eastern edge of the park on Bartman's Hill. Click here to read information about the Maryland portion of the Appalachian Trail.

Plan Ahead for "Filled To Capacity" Park Closures

Greenbrier State Park is one of Maryland’s most popular parks and serves a very high volume of visitors during summer weekends and holidays. To ensure the safety of our visitors and protection of the park’s natural resources and facilities, the park has a limited capacity.

During periods of high visitation, when the park’s capacity is reached, the park will be closed and traffic will be turned away from the park entrance. When that occurs, no additional vehicles / visitors will be allowed to enter the park, including those with members of their party who may already be in the park. If you are not traveling in the same vehicle with others in your party, we suggest that you all arrive at the same time.

When the park is closed due to being full to capacity, individuals and groups with shelter and/or camping reservations will be admitted, as parking is reserved for those purposes.

Based on recent experience and visitation trends, and depending on good weather, Greenbrier State Park will likely fill to capacity and close on Memorial Day and Fourth of July holiday weekends, Labor Day weekend and many other weekends during the course of the summer. Please take this into consideration when planning your trip.
