Caledonia is located on the northern-most section of the Blue Ridge Mountains known locally as South Mountain. Blue Mountain, the eastern-most ridge of the Allegheny Mountains, is located to the west and northwest of the park across a large low, rolling, fertile valley known as the Great Valley. South Mountain is mostly made of a hard rock called quartzite. The valleys on either side are underlined with limestone and shale. The soil is ideal for fruit production proven by the abundance of orchards in the surrounding area. Caledonia brings to nature lovers 1,125 acres of mountainous terrain with the entertainment of an 18-hole golf course and the Totem Pole Playhouse, a summer stock theater around since 1952, which offers daily performances during the summer months.

• Hike along the Appalachian Trail which traverses the central portion of the park.
• Golf at the 18 hole, par 68, public golf course. Constructed in the late 1920s, the Caledonia course is the oldest and one of the most scenic courses in south central Pennsylvania.
• See the daily performances during summer months at the Totem Pole Playhouse, a summer stock theater located in the park since 1952.
