Pillar Point Bluff
The Jean Lauer trail winds through Pillar Point Bluff County Park and overlooks a seasonal wetland and coastal waters. You may see pelicans, cormorants, or hawks flying over this ADA-accessible trail with low grades and abundant scenery.
Castle Rock State Park
During the winter at Castle Rock State Park, hikers can stand on a wooden platform above a waterfall that careens 75 feet down into the San Lorenzo River. Besides chasing waterfalls, you’ll find impressive sandstone formations, sweeping vistas, and ancient redwoods.
Fremont Older Open Space Preserve
At Fremont Older Open Space Preserve in Santa Clara, trails wind through beautiful forests and rolling hills to the top of Maisie’s Peak. Panoramic views of the surrounding open spaces can be found at the summit, and blue elderberry, coyote brush, and monkey flower are found along the way.
Rancho Cañada del Oro Open Space Preserve
Rancho Cañada del Oro Open Space Preserve is a great place to see wildflowers in the springtime. The trails here wind through native grasslands, oak woodlands, and creekside habitats, which tend to flourish after the stormy winter months.
Long Ridge Open Space Preserve
Long Ridge Open Space Preserve is a great hiking destination all year long, though its lovely wildflowers make it a great choice for the springtime. At the top of the ridgeline, you’ll discover sweeping views of the Pacific ocean and surrounding forests.
Cowell Ranch State Beach
Just north of Half Moon Bay, the Cowell Purisima Coastal Trail features pastoral scenery on one side and ocean views on the other. This flat trail is perfect for a slow, meandering hike. Keep an eye out for harbor seals, pelicans, hawks, and wildflowers.
Rancho San Antonio Open Space Preserve
The High Meadow Trail Loop at Rancho San Antonio Open Space Preserve features a variety of scenery. The trail begins in a cool canyon, and then ascends to high meadows filled with lupine, poppies, and blue-eyed grass.
Sanborn County Park
This hike along the Skyline and Indian Rock trails is mostly flat and almost completely shaded, making it perfect for a hot summer day. You’ll journey along the ridgeline of the Santa Cruz Mountains through Douglas fir and Pacific madrone.
San Mateo County Park
The Devil’s Slide Trail was converted from a former section of Highway 1, and is now a popular spot for both hikers and nesting seabirds. Along this short paved trail, you’ll find ocean views, observation scopes, and interpretive signs.
Stevens Creek Nature Study Area
Levee Trail at Stevens Creek Shoreline Nature Study Area is a prime spot for birders. Though the trail is short, it’s an ideal place to observe swallows, sandpipers, herons, coots, shovelers, and more. Plus, the hike can be easily extended along the San Francisco Bay Trail.
Windy Hill Open Space Preserve
On a clear day at Windy Hill Open Space Preserve, three mountain peaks are visible from the summit: Mt. Diablo, Mt. Hamilton, and Mt. Tamalpais. Though a strenuous hike to the very top, the stunning views make the journey worthwhile.
Sam McDonald County Park
This moderate hike through the redwoods leads to the cabin where Sam McDonald, Stanford’s first Black administrator, once lived. Keep an eye out for banana slugs and California newts, who are more common during the wet winter months.
