The 1,125-acre Caledonia State Park is in Adams and Franklin counties, midway between Chambersburg and Gettysburg on US 30. Caledonia is in the northernmost section of the Blue Ridge Mountains known locally as South Mountain. Blue Mountain, the easternmost ridge of the Allegheny Mountains, is to the west and northwest of the park across a large low, rolling, fertile valley known as the Great Valley. South Mountain is mostly composed 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.

Good hike, a little confusing around the maintenance building.
Really didn't care for walking along the highway though.

A very pleasant hike! I would not say it is lightly trafficked on the A.T. part, but the Hosack Run Trail was pleasant with quiet campsites and few people! I would not consider this as a difficult trail, but easy-moderate. The scenery is nice with the A.T. green tunnel and the flowing water sources, but it is also rocky! Such a lovely hike!

solid with a dog great for a shakedown

awesome. trail was Rocky though needed better shoes. plenty of helpful people and water everywhere.

Good trail with a mix of scenery. There are two places to park- the campground (you'll walk up a gravel road) or the start of the loop (drive up the dead end/gravel road).

Good Route- worth the time. Counter clockwise from the Parking area is less steep.. the AT is a climb along well worn trail. There are several good sites along this route...
