Several short and widely separated sections of the canal have been rewatered and offer boating opportunities. Boats need to be carried around lift locks. Listed below are the watered sections of the canal.
Mile 0 to 22 Georgetown to Violettes Lock
Use of electric motorized vessels is allowed only at Big Pool, Little Pool, and canal waters from Lock 68 to Town Creek Aqueduct. Gasoline and propane motorized vessels are prohibited within the park. Personal floatation devices should be used as required by the state of Maryland. Use special care if boating on the Potomac River. Canoeing on the Potomac should be done under the direct supervision of an experienced adult canoeist. Boat launch ramps are available along the canal. See the Recreational Guide for locations.
