If you head west on Route 30 past Gettysburg, you will come across two state parks. The larger of the two is Caledonia State Park. The 1,125-acre park is in Adams and Franklin counties, between Chambersburg and Gettysburg along the Lincoln Highway (US 30). It is situated within South Mountain, the northern terminus of the well-known Blue Ridge Mountain of Maryland and Virginia. The soils on either side of South Mountain are ideal for fruit production, proven by the abundance of orchards in the surrounding area.

Some unique features at Caledonia are a golf course and the Totem Pole Playhouse. It also provides hiking, camping, and hunting and hosts the Pennsylvania Forest Heritage and Discovery Center.

Nearby Mont Alto State Park is a quiet, 24-acre park which features a pavilion, picnicking, and trout fishing. Mont Alto is the oldest park still in the Pennsylvania state park system.
