Welcome to Coastside State Parks Association

The Coastside State Parks Association (CSPA) supports fifteen California State Parks along 36 miles of San Mateo County coastline from Gray Whale Cove State Beach in Montara in the north to Año Nuevo State Park in Pescadero to the south. In partnership with California State Parks, CSPA raises funds to support vital education and interpretation programs and projects.

This map shows the State Parks and Beaches that we support.  To learn more about these State Parks and Beaches, scroll down through this list.



Mark Your Calendar for Coastal Wildflower Day 2015

Saturday April 11, 2015, 10 AM – 4 PM
Half Moon Bay State Beach, 95 Kelly Ave

California State Parks and the Coastside State Parks Association invite you to a day-long festival celebrating the return of spring wildflowers and the start of California Native Plant Week. There will be opportunities to explore coastal wild lands, learn about our native plants and how you can grow them in your garden, and take part in projects to restore the coast. The event will be fun for the whole family, including games and crafts for all ages.

Coastal Wildflower Day activities are free but parking is $10 unless you have a State Park pass. Walk or ride your bike if you can.
