Little Pine Mountain, Mountain summit in Santa Barbara County, United States.

Little Pine Mountain is a summit in Santa Barbara County that reaches approximately 4,460 feet in elevation. The slopes support a mixed forest of Coulter pines along with scattered chaparral vegetation typical of the area.

The mountain formed over millions of years through geological processes involving Franciscan rock assemblages, the Espada Formation, and Matilija Sandstone layers. These rock types remain visible in the mountain's structure today.

The name comes from a thin grove of Coulter pines on the summit, a tree found on few other peaks in the range. In winter, Santa Barbara residents use the Santa Cruz National Recreation Trail as a day hike and mountain-bike route, and a camp at Happy Hollow Spring sits near the top.

The Santa Cruz National Recreation Trail provides the main access route to reach the summit and requires proper hiking gear and ample water supplies. Be prepared for exposed sections and changing weather conditions at higher elevations.

A band of Temblor Formation rock, part of the Great Valley Sequence usually found far to the north, encircles the high ridge of Little Pine Mountain. The summit itself is Matilija Sandstone, and a strip of serpentinite splits the Espada Formation on the north slope.
