Hike Across Maryland (HAM) on the Appalachian Trail

The Hike Across Maryland HAM is a rigorous way to spend Memorial Day weekend on the Appalachian Trail, with a single-day 41-mile traverse from Pen Mar Park at the Maryland Pennsylvania border to Harpers Ferry. You start at first light to stay ahead of the elevation changes and rocky footing, and you should arrive prepared for a long, technical day. This is built for experienced long-distance hikers who want an endurance test, not a casual walk.

Your day runs checkpoint to checkpoint, with nine supported stops offering water, snacks, and medical support. This is a personal challenge rather than a race, but time cut-offs at specific stations keep the field moving and help ensure a safe finish. Along the way you get sweeping ridgeline views and the steady encouragement of other hikers, and the final steps into Harpers Ferry feel earned, right where the Potomac and Shenandoah meet.

Plan early and pack smart. Registration often fills months ahead, and rates start at $60 with camping, breakfast, and a commemorative shirt included. We recommend arriving at Camp Round Meadow in Catoctin Mountain Park the night before for the included lodging and early shuttle, then carrying your own high-energy snacks and electrolytes as insurance between stations. Wear broken-in trail shoes and moisture-wicking socks, check the forecast, and bring a lightweight rain shell since conditions can shift quickly.

Good to know before you commit: you must be at least 12 years old, and pets are not allowed due to distance and logistics. The event goes on rain or shine unless conditions are unsafe, and support vehicles can pick you up at checkpoints if you need to exit early. There is no formal gear list, but trekking poles and a headlamp for the early start are strongly recommended. If you want a hotel bed before or after, consider Hagerstown or lodging near Harpers Ferry, or book a cabin or vacation rental through Lake.com for a quiet recovery base.
