The C&O Canal Trust wants your visit to be safe and enjoyable. Please be considerate of others while in the park and abide by all regulations.

Potomac River
Swimming in the Potomac River, while often inviting, is discouraged. Nearly every year there is at least one drowning. Generally these tragedies occur when people unfamiliar with the river underestimate its power and depth. Another significant hazard to swimmers comes in the form of bacteria that can be found in the water, especially after rainstorms.

General Etiquette
Hikers, bicyclists, strollers, joggers, birdwatchers, young children, and, in places, horses, share the towpath. To avoid conflicts, please be respectful of your fellow visitors and move to the right to allow others to pass. If you are in a congested area, use caution and slow down to avoid accidents.

Please stay on the towpath or other marked trails while in the park. Doing so will minimize erosion and disturbance of sensitive plants and wildlife. Efforts to maintain and improve trails are ongoing throughout the park; you can help this effort by observing trail signs and regulations.

Keep in mind that visitors are prohibited from removing rocks, plants, or artifacts from the C&O Canal NHP. This is essential to ensure that the canal maintains its historical and ecological character for future generations to enjoy.

The C&O Canal is a “Trash Free Park” which means if you bring something into the park, you need to take it with you when you leave. There are very few trash cans available; however, plastic bags are free for the taking at most points of entry.

Natural Hazards
Poison ivy can often be found growing along the towpath and in other disturbed areas of the park. Also, ticks may hitch a ride on clothing or exposed skin if you explore in or near tall-grass areas. Always do a post-hike check on both yourself and your dog. Keeping to established trails will minimize your exposure to these hazards.

Pet Etiquette
Dogs are welcome throughout the park, however it is important that they are kept on leashes to ensure the safety and comfort of all of our visitors and to protect the park’s flora and fauna. Dog owners are also expected to collect and remove their pets’ waste.
