You can now request your free annual park pass online! The Mariposa Program allows eligible individuals and families to ask for their annual park pass online. It has been two years since the San Mateo County Board of Supervisors voted to provide yearly park passes for low-income residents. This initiative has been important and unique in making public green spaces accessible to all. The new online system is more convenient, and it offers a preferred language option to complete a five-question form. Click here to find out if you are eligible and apply!
