Marin County public health officials shut down all county parks Sunday as waves of outdoor enthusiasts continued to pack into West Marin in violation of a “shelter in place” order aimed at stopping the spread of the coronavirus.

All Marin parks from large to small are closed effective immediately until further notice, the county said in a plea sent Sunday, calling on citizens and the media to encourage others to heed the order to safeguard public health.
