About the Park
Sir William's Dog Run brings a touch of formality to upper Manhattan's 10040 zip code, in the Fort George and Washington Heights area. The knightly name aside, the documented facts are workmanlike: off-leash use is allowed and the run is free. Fencing, surface, and hours are not in our records, so inspect the space and posted rules before your dog runs free. Upper Manhattan's ridgeline geography means parks here often involve hills and stairs, good exercise for both ends of the leash. Summers are humid, winters are windy at elevation, and water is not a documented amenity, so bring your own. A no-cost neighborhood option that merits a scouting trip.
infoWhat to Know Before You Go
Sir William’s Dog Run is fully fenced, so your dog can run and play off-leash without worry. This makes it a great choice for dogs still working on recall or for owners who want extra peace of mind.
Best of all, Sir William’s Dog Run is completely free to visit — no membership or daily fees required.
backpackWhat to Bring
Fresh water and a bowl
Even parks with water fountains can have them out of service. Bring your own to be safe.
Poop bags
Most parks provide them, but don't rely on it. Always come prepared to clean up after your dog.
A folding chair
This park may have limited seating, so a portable chair can make longer visits more comfortable.
A reflective collar or light-up leash

High-value treats

Your dog's favorite toy
