Outdoor Recreation, Parks, Playgrounds and Trailhead Information

Should I wear a mask when participating in outdoor recreation or exercise?
On April 17, Marin County Public Health announced a public health order requiring the use of face coverings when completing essential activities. This order, which remains in effect, requires most individuals to wear a face covering when they are interacting with others who are not members of their household in public and private spaces. Any child aged two years or less must not wear a face covering because of the risk of suffocation.

You do not need to wear a face covering while you are exercising outdoors by yourself, but you must keep one with you at all times to put on when you see someone approaching and ensure your nose and mouth are securely covered by the time you get within six feet of them. Each person engaged in such activity must comply with Social Distancing Requirements including maintaining at least six feet of separation from all other people to the greatest extent possible.
