Heart of the Civil War GeoTrail


About the GeoTrail

The Heart of the Civil War Heritage Area GeoTrail takes geocachers through three counties in Maryland that saw major moments of the Civil War. Highlighting battlefields, museums, historic city centers and other significant sites in Carroll, Frederick, and Washington Counties, the trail is a fun and educational activity for geocachers of all experience levels. In 2021 we added new sites to the Geotrail with the help of volunteers from the Maryland Geocaching Society.

An exciting addition to the trail in 2021 is the Adventure Lab: participants can take on the role of a Civil War correspondent hot on the trail of a Confederate spy. Players must solve puzzles and collect information along the trail in all three counties in order to identify the spy and complete the Adventure Lab.
