Things to Do
Maryland state parks highlight the state’s geographic diversity, stretching from the Appalachian Mountains to the Chesapeake Bay and the Atlantic Ocean. Visitors can enjoy ocean swimming and wild horse watching at Assateague, hiking the rugged Appalachian Trail, boating and crabbing in the Chesapeake Bay estuaries, and fishing for trout in mountain streams. Other popular activities include mountain biking through extensive forested watersheds, exploring Civil War and colonial history, camping in both beach and mountain settings, and kayaking calm tidal rivers.
Best Time to Visit
Spring and fall are the most comfortable seasons for outdoor recreation in Maryland. Fall (October) brings crisp air and excellent foliage in the western mountain parks. Spring offers pleasant temperatures and blooming wildflowers. Summer (June–August) is peak season for coastal and bay parks, though inland parks can be very hot and humid. Winter is mild in the east but brings enough snow for winter sports in the westernmost parks like Deep Creek Lake.
Visitor Tips
Entry fees vary widely: some parks charge per vehicle (around $3-$5), while others charge per person, and out-of-state visitors generally pay slightly more. A Maryland Park Service Annual Passport ($75 for residents) provides unlimited day-use entry. Popular parks, especially beaches and those near Baltimore/Washington D.C., frequently reach capacity and close early on summer weekends and holidays, so arrive before 10 AM. Dogs are allowed in many areas but have strict seasonal restrictions on beaches.
