Devil’s Slide Coast: a collection of protected lands and marine areas that starts just north of the Devil's Slide Tunnel and stretches to the famed Mavericks surf break.

From the beginning, Devil’s Slide Coast has been rugged and full of adventures. Today, we can access its majestic places and experience their biodiversity, history, and natural beauty in new ways.

Before 1769

It is estimated that between 1500 and 2500 native people inhabited the Peninsula region at the time of European contact. They were organized into small local tribes. Fewer than 100 people lived in the area now known as Pacifica. They called themselves Aramai.


Standing on Sweeney Ridge in the fall of 1769, Spanish soldiers of the trail-blazing Gaspar de Portolá expedition were the first Europeans to lay eyes on San Francisco Bay.
