Update May 5, 11am:  King County Parks will open on Friday, May 8!

On May 8, we are re-opening our parks and trails, including regional and back country trails, with some restrictions. Facilities, such as restrooms, play areas, sports courts, and picnic shelters, remain closed, and organized events and programs remain suspended.

Please help keep Marymoor Dog Park open by following these “Recreate Responsibly” Guidelines:

  • “Keep your Distance” by staying at least 6ft away from other park users. Recreate with those in your household. Give others plenty of room and communicate who will step aside on the trails and who will cross the bridges first.  

  • “Stay local.” Don’t stray too far from home when recreating and keep the city communities near the park safe by minimizing stops and bringing all that you’ll need for your outing.

  • “Keep it Moving!” Use park fields and trails for walking/running & passing through.  No Gatherings & No Congregating.

  • “Plan ahead.” Be prepared to go somewhere else if the park seems crowded. Add hand sanitizer and a mask or other face covering to your “Take-Alongs”.

  • “Play it safe.” Assess your health vulnerability level before leaving home to reduce the risk of getting sick and putting extra burden on our health care and emergency services.  

  • “Leave no trace.” Take any personal garbage home with you, especially disposable face masks and gloves.  As always, be sure to clean-up after your dog/dogs and dispose of pet waste in trash cans. 

The health and safety of residents and Parks employees is paramount. Parks will continue to monitor its parks and trails to ensure that visitors are following physical distancing and other public health guidelines. King County Parks encourages visitors to do their part and keep each other safe so that King County’s parks and trails can remain open.
