Swimming at Greenbrier State Park

If you’re planning a visit to Greenbrier State Park between early May and late September you’ll be able to enjoy swimming in the park’s 42-acre freshwater lake.

Hiking at Greenbrier State Park

Greenbrier State Park’s 11 miles of trails extend throughout the surrounding area and connect with trails leading outside of the park. Most of these trails consist of steep hills, rocky terrain, creeks, and scenic overlooks as they climb into the mountainous forest.

Trails lead from inside Greenbrier State Park to Annapolis Rock and Black Rock, and also over to Washington Monument State Park. These trails also connect to the legendary Appalachian Trail, the 2,168 mile long hiking trail that extends from Georgia to Maine. Maryland is home to 40 miles of this famous trail.

Guests interested in exploring the Maryland section of the Appalachian Trail may purchase a guide to the Appalachian Trail inside the Visitor Center and head out along the trails leading from inside Greenbrier State park. Shelter and campgrounds are located along the trail. If this sounds exciting to you, plan ahead for a strenuous hike up steep slopes by wearing appropriate footwear and carrying snacks and plenty of water.

Also be aware that several trails surrounding the park are in public hunting areas. If you plan to visit between September and January, or in April or May make sure you wear bright colors while hiking.

Here are a couple of the trails at Greenbrier State Park:

  • The Big Red Trail – A moderate 5.2 mile loop that winds along a rocky path through the forest and by creeks and the lake.
  • The Bartman Hill Trail – A difficult 0.6 mile trail. This steep trail starts near the Visitor Center and connects to the Appalachian Trail.
  • The Rock Oak Fire Trail – Moderate 1.5 mile trail that flows through the woodlands and along the lake. It also runs parallel to the Snelling Fire Trail.
