California's famous national and state parks get all the attention, but some of its best wild spaces are run at county level — and one of the easiest to reach sits on the edge of Silicon Valley. Sanborn County Park covers 3,453 acres of the Santa Cruz Mountains, roughly a 30 to 40 minute drive from San Jose and about 90 minutes from San Francisco. Designated in 1977, it's a dense woodland of coast redwoods, tanoaks, Douglas firs and madrones, with a short hop from Los Gatos, one of the region's more underrated wine towns.
Most of the redwoods here are second growth, since logging stripped much of the original coastal forest from the 1850s onward. Look for the "fairy rings": circles of younger trees sprouting from the root systems of long-gone giants around old stumps. The park opens at 8 a.m., has picnic spots, restrooms, and even wedding sites under the canopy.
Hiking is the main draw, with more than 23 miles of trails. The 1.8-mile San Andreas and Nature Trail Loop is an easy, family-friendly favourite — flat-ish, shady, and passing creeks where you can spot California newts. Want more of a workout? The 4.2-mile San Andreas Trail to Peterson Memorial Trail climbs 1,233 feet for wide valley views; poles recommended. On the quiet southern side, the 10.5-mile John Nicholas Trail doubles as a solid mountain-bike route with plenty of viewpoints, and being out-and-back you can tackle just a section.
Wildlife worth knowing about includes black-tailed deer, wild turkeys, coyotes, red-tailed hawks and rattlesnakes — so check logs and rocks before you sit. Poison oak is common, too.
Camping is where Sanborn really earns a weekend. There are three campgrounds: a year-round RV area with paved sites, electrical and water hookups, showers and a dump station (no tents allowed there); a seasonal tent-only campground with 33 hike-in sites, some tucked right against the redwoods — note that higher-numbered sites mean a steeper haul, and each site caps at six people; and a group walk-in campground for up to 35. All bookings go through the Santa Clara County Parks website. Campground etiquette doubles as redwood conservation: pack out your rubbish, don't touch the bark, and stick to marked trails.
Why it matters: this is one of the most convenient redwood experiences in the Bay Area — no national park booking lottery, no long drive up Highway 1. It works equally well as a morning hike for San Jose locals, a family nature loop, or a proper overnight under old-growth-adjacent giants. Add Cupertino, 15 minutes away, if you want a tech-flavoured detour and a glass of local wine afterwards.
