Cerro Cabrillo

Cerro Cabrillo is a rocky summit within Morro Bay State Park featuring steep slopes covered with native plants and brush. The peak displays volcanic rock formations that create the dramatic terrain visitors encounter on the trail.

The mountain formed roughly 20 million years ago through volcanic activity and ranks among the Nine Sisters, a chain of ancient volcanic peaks. This geological formation resulted from a period when magma pushed upward beneath the region.

The summit is named after Spanish explorer Juan Rodriguez Cabrillo, and hikers can spot Tiki Rock along the way, a natural stone formation that resembles Polynesian carvings.

Reaching the summit requires a hike of roughly 2.5 miles round trip starting from South Bay Boulevard, with rocky and steep sections throughout. Wear sturdy shoes and bring plenty of water, as the trail is exposed to sun and offers little shade.

The mountain hosts uncommon plant species including Deer Weed, Soap Plant, and Chaparral Checkerbloom that thrive in its volcanic habitat. These plants have adapted to the dry conditions and rocky environment found at this elevation.
