Being outdoors has many benefits. It can improve attention span, reduce stress and motivate people to exercise. In San Mateo County, there are a lot of outdoor spaces that we can enjoy! The Mariposa Program helps you get free entry to some of those outdoor spaces.
The Mariposa Program is offered by San Mateo County’s Parks Department and the Human Services Agency (HSA). 
Through the program, you can get a park pass to enter San Mateo County Parks for free. To get a free park pass, you must meet at least one
of these:
- Be an HPSM Medi-Cal, CareAdvantage or ACE member.
- Be enrolled in CalFresh or CalWORKS.
You can use the park pass to walk along the bay or reservoir, hike trails, bike, enjoy ocean views, go to a playground and more at San Mateo County Parks! The park pass can be used for 12 months from the date it is issued. It covers the entrance fee to these parks:
- San Bruno Mountain in Brisbane
- Junipero Serra Park in San Bruno
- Coyote Point Recreation Area in San Mateo
- Huddart Park in Woodside
- San Pedro Valley Park in Pacifica
- Sam McDonald Park in Loma Mar
