King County Parks and Seattle Parks & Rec have issued new rules for county and city parks in order to help reduce the spread of COVID-19.
Parks remain open to the public and people are encouraged to get outside to exercise and enjoy nature. Just make sure you keep social distancing in mind and avoid park areas where bottlenecks may force people close together.
Some park ammenities are now closed until further notice. These include playgrounds, picnic shelters, and all active recreation areas like sports courts and ball fields. You can see the full announcement here.
