Holiday Hike AT: Pen Mar Park - Caledonia State Park! A Very Strenuous 17.9 Mi

  • Holiday Weekend AT Section Hike: Pen Mar County Park to Caledonia State Park— Featuring 6 Rock Scrambles  Mt. Dunlop Summit, Chimney Rocks, Waynesboro Reservoir, Snowy Mt. Fire Tower! A Very Strenuous 17.9 Mile Hike

    Driving Distance from D.C. is only 76 miles which is much closer than both Shenandoah National Park and George Washington National Forest for hikers coming from or near D.C.!

    Starting from Pen Mar, you start by walking in the past - where the Western Maryland Railroad built and maintained an amusement park for sixty years.  Continuing north on the AT, you make your way over Mt. Dunlop to reach the Old Forge Picnic Grounds of Michaux State Forest. There are several rock scrambles along the way! The section from Old Forge Picnic Grounds to Caledonia is considered one of the most delightful day hikes in Pennsylvania.

    Out of the Antietam Cove area, once the extended Blue Ridge, is gained on what is known locally as South Mountain, where there are several excellent views, an unexpected boggy area, and a good half dozen rock outcroppings to scramble through before a gradual descent into the valley that holds Conococheague Creek and Caledonia State Park.

    Pre-Approval Required for this Very Strenuous Hike
    (Requirement Waived for Members Who Have Earned Mid-Atlantic Hiking Group’s “Pre-Approved for Very Strenuous” Hikes Badge) You must contact the hike leader BEFORE signing up for this VERY Strenuous hike. The reason for this requirement is so that you and the hike leader can make an informed decision together as to whether this is a hike for you at this particular time. Hiking beyond your current physical limitations is dangerous and puts everyone, including yourself, at risk. At 48 hours before the hike, if anyone is signed up for this hike without first contacting the hike leader and gaining approval to attend will have their RSVP updated to “not attending” and no refund issued. (this is to encourage people not to fill up the hike without first getting approved). We appreciate your understanding and let's all have a great adventure!
