Monocacy River Water Trail

Monocacy River Water Trail

The Monocacy River Water Trail is a self-guided tour of the river for canoeists and kayakers from the Monocacy Battlefield to the Monocacy Aqueduct in Maryland. The trail takes paddlers through landscapes once inhabited by Native Americans and early European settlers who were attracted to this fertile valley.

It provides opportunities to observe diverse wildlife and historic sites. The trail also provides river travelers with a new perspective on the resources of the Monocacy that inspires commitment to conservation and restoration.

Please note that boating, canoeing, kayaking and other activities on rivers can be dangerous. Obtain a water trail map and guide in advance, plan your trip, and follow all safety precautions.

Scenery is rolling farmland with rock outcroppings, historic features and bridges, and overhanging trees.
