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.

Wild rhododendrons were amazing a lot of the trail was just filled with them literally 15 to 20 feet tall and Trails made through them where it actually appeared like a tunnel. Thick vegetation made it hard to really see the views although we had several views of large boulders on the mountain side. The trail was very well-maintained with lots of views of the stream. You could hear it too many places . Majority of the trail was wide. The elevation zigzagged back and-forth to the top of the mountain ( first half your climbing up) you reach the top of the elevation and it is quite a climb. The descent was well-maintained with a series of steps built into the mountainside that were just amazing. The massive wood notched beams that cross the creek was a perfect spot to rest and get more photos

This is a great trail if you’re looking for something challenging and rewarding. The switchbacks are super fun and the peacefulness is the best on this trail! Wear waterproof shoes as there is water to cross. Happy Trails!

This an easy and short walking trail. We like to take the kids walking here and it is doable in the rain.

Nice steady up and down

Beautiful trail for a quick hike. Interesting history in the area as well.

Great hike, slow incline, steep incline.
Places to sit at the top yo test and/or enjoy the area.
Only negative, I lost my sunglasses.
Trekking poles are beneficial at times on this trail
We clocked a little more mileage then posted, paled at campground at the start, completed with 6.88miles.

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...

great hike... perfect for a late afternoon early evening...

With two kids, ages 8 and 10, it was an absolute hit! The tree canopies, water elements, and rock features...we will definitely do this hike again!

Easy day hike with some beautiful scenery


I loved this trail. I did the charcoal hearth walk. It was challenging, but a lot of fun (I should mention that I'm 5'3" and weigh about 240, don't judge!). I would not recommend doing this trail after a re entry rain, it is slippery. This would have been a 5 star trail if there had been a view. But it is a really nice walk in the woods.

A nice hike with numerous campsites, an Appalachian Trail shelter, and stream. The lead up to the loop is a forestry road, so next time I'll begin at the loop, branching off to explore the AT on an out-and-back to add some distance.

Very nice day! Met Jim good man takes care of the trail very well.

Day hiked this shit a few years back now. Great views and elevation

A great day-hike with some amazing wandering through forests of rhododendron. Can't wait to hike this in May/June when the flowers are in bloom. Definitely start on the Locust Gap Trail heading northeast (up the mountain) and end on the AT heading south. The footing on the Hosack Run Trail is difficult in some parts and much easier heading up than coming down. A great hike!

This was my first time. Was more then I expected. Will definitely be go back for more.

We walked the 2 mile Ramble trail. It was late in the day, so we didn't want to commit to something more than we needed to. This was perfect for that! Very flat, nice scenery, and the fall colors were coming through. If we had more time, we would have wanted more elevation change, but this is perfect for someone who wants a walk in the woods. The only drawback was the sound of the nearby road for pretty much the whole hike.

A great, moderate hike for beginning backpackers. Plenty of water sources and the most difficult parts are not that long. We hiked from Caledonia State Park up the AT and around the loop to Rocky knob trail where we camped the night. We then hiked back for a total of 14 miles. Going back to do the rest!

not as easy on a hungover Sunday as Carol would lead you to believe but overall a great 5-7 mile trek.

Walked the 2.0 mile Ramble trail. It is very easy going and easy on the eyes. Highly recommended for those who want a walk in the woods without having to climb.

Took the charcoal hearth trail from the parking lot before you get to the park office. The hike was challenging, as it was pretty steep initially, but was beautiful! My dog appreciated the last leg of the trail which runs beside a little creek-she walked & played in it the entire way! I would definitely recommend this loop trail and will be back to explore others in the park!

We did a day hike from Old Forge to Caledonia..definitely made the right decision by starting south and heading north. We are novice hikers, but we really enjoy this hike and the challenges it gave us...with a few breaks, and a nice scare from a snake, it took us 6 hours...

Had a great time on this trail. Not to bad of a hike with a great view. At theology out point there was a ravens nest just off the side of the cliff. We stayed in the tumbling run shelter just to camp out and it was a really nice campsite.
