Mont Alto State Park
"Carlisle residents use Mont Alto State Park as a low-key alternative to busier parks, choosing it for family reunions, shaded summer picnics, and access to the South Mountain landscape."
A small, historic day-use park on South Mountain, Mont Alto State Park features shaded picnic areas, a stone swimming pool, and trout fishing along Antietam Creek. It provides a quiet retreat with easy access to nearby state forest and Appalachian Trail segments.
