Off-leash dog area
"Doggy Disneyland", as it is locally dubbed, Marymoor Park is best known for its 40-acre off-leash dog area. This is where dogs can be dogs. Black Labs dogpaddle against Golden Retrievers to see who can get the prize: an old tennis ball thrown by a dog owner into the Sammamish Slough.
This fabulous former farm is less than two miles from the main Microsoft campus. It is a great place to meet old friends and make new friends, both two-legged and four.
Dogs must remain on leash when outside of the boundaries of the designated off-leash area. Dogs are not allowed on fields with active play or on playgrounds.
