South Mountain State Park is an undisturbed outdoor recreation area near the South Mountain Ridge and the Potomac River. It has no recognizable entry point but can be accessed from a few different locations by foot. The ridge top of South Mountain is part of the Appalachian National Scenic Trail, and the mountain has several spectacular vistas from which hikers can see the entire valley below. A variety of wildlife can be observed within the park, but visitors should keep their distance; hunting is allowed with the appropriate licenses. Keep your Myersville camper rental nearby, and you can return to the lap of luxury when your outdoor excursions are done. Greenbrier State Park is a multi-use outdoor recreation area centered around a human-made lake in the Appalachian Mountains. The lake has a sandy beach where guests can enjoy swimming; boating and fishing are allowed on the lake, and there are miles upon miles of hiking trails winding through various habitats. It has a visitor's center, picnic areas, and some camping spots; a beach wheelchair can be borrowed if necessary. Antietam National Battlefield is the final resting place of the soldiers who died at the Battle of Antietam, Robert E. Lee's first northern invasion in September of 1862. Thousands of soldiers were lost in the battle. The confusion caused by the aftermath of the battle led to haphazard burial plans, and by 1864, a plan was drawn up to create a proper graveyard for the soldiers' remains; the cemetery was completed by 1867, and then-president Andrew Johnson and other dignitaries attended its formal opening. Today the historic area serves as a reminder to what happened and what was lost.
