Overview
Sanborn County Park is a 3,688-acre Santa Clara County park tucked into the western slopes of the Santa Cruz Mountains, just outside the town of Saratoga. The park preserves one of the more accessible stands of second-growth coast redwood in the San Francisco Bay Area, offering a genuine forest experience within roughly an hour of Silicon Valley.
The park is managed by Santa Clara County Parks and is a popular weekend destination for hikers, mountain bikers, and campers who want to escape the urban sprawl of the South Bay without a long drive. Its relative proximity to major population centers means it can feel busy on sunny weekends, but weekday visits are typically quiet and unhurried.
The park is also notable as the eastern trailhead for the Skyline-to-the-Sea Trail, a long-distance route that runs west all the way to Waddell Beach on the Pacific coast. This connection makes Sanborn a logical staging point for multi-day backcountry trips through the Santa Cruz Mountains.
Before You Go
No visa information specific to this park is applicable beyond standard US entry requirements. For current US entry rules, check TravelerPulse's Visas section and the official US Customs and Border Protection website.
Permits and Reservations
- Day-use parking fees apply; verify current rates on the Santa Clara County Parks website before your visit.
- Campsite and group area reservations are strongly recommended, particularly for spring and summer weekends. The county uses an online reservation system — confirm availability and book well in advance.
- Dogs are permitted in some areas of the park but are restricted from certain trails; check the current pet policy before bringing animals.
What to Pack
- Layers are essential year-round. Even in summer, the redwood canopy keeps temperatures noticeably cooler than the surrounding valley, and morning fog is common.
- Bring sufficient water; reliable potable water sources in the backcountry should be verified locally before you rely on them.
- Sturdy footwear is recommended as many trails involve uneven, root-covered terrain.
- Cell service is limited inside the park — download offline maps before you arrive.
Getting There
Sanborn County Park's main entrance is located on Sanborn Road in Saratoga, California. Saratoga is a city in Santa Clara County, roughly 10 miles west of San Jose.
By Car
The park is most conveniently reached by private vehicle. From central Saratoga, head west on Big Basin Way (Highway 9), then turn onto Sanborn Road. Parking is available at the main day-use area and near the campground; a per-vehicle day-use fee applies.
By Public Transit
Santa Clara Valley Transportation Authority (VTA) bus service reaches Saratoga proper, but the final stretch to the park entrance involves several miles of uphill road with no dedicated transit service. Check the VTA trip planner for current routes and stops, and note that a bicycle or rideshare connection may be needed for the last segment.
By Bicycle
Cyclists comfortable with moderate climbing can reach the park via Saratoga-Los Gatos Road or Highway 9. The climb to the entrance is sustained and not suitable for casual cyclists, but the route is manageable for experienced riders.
Getting Around
Within the park, travel is on foot or by mountain bike on designated multi-use trails. The trail network connects to adjoining Castle Rock State Park to the north and to the Skyline-to-the-Sea corridor, giving confident hikers access to a much larger trail system.
A trail map is available at the park entrance station and is also downloadable from the Santa Clara County Parks website. Trails range from easy loop walks near the campground to strenuous ridgeline routes. Signing at junctions is generally good, but carrying a downloaded or paper map is advisable given limited cell connectivity.
Things to See & Do
Hiking
The park offers roughly 15 miles of trails within its own boundaries. Popular routes include the Sanborn Trail, which climbs through redwood groves, and the Todd Creek Redwoods Loop, a shorter option well-suited to families. The connection to Castle Rock State Park via the Skyline Trail opens up access to sandstone rock formations and more sweeping ridge views.
Camping
Sanborn has tent campsites, RV sites with hookups, and a hike-in/bike-in area. The campground sits among trees and is a comfortable base for multi-day exploration. A full-service group camping area accommodates organized groups; advance reservation is required.
Historic Sanborn Hostel
The park contains a historic log building that has operated as a hostel (managed through Hostelling International affiliates at various points in its history). Availability and current operational status should be verified directly with the county parks department or the hostel operator before planning to stay there.
Mountain Biking
Several trails in the park permit mountain bikes. The connection to the larger Santa Cruz Mountains trail network makes this a reasonable starting point for longer rides, though some connecting trails in adjoining parks may have different use rules — confirm before setting out.
Nature and Wildlife Observation
The redwood understory supports varied birdlife, including Steller's jays, spotted towhees, and, occasionally, owls. Deer are commonly seen near the campground at dusk. Newts cross trails during wet months, so watch your step in winter and early spring.
Food & Drink
There are no food concessions or restaurants inside Sanborn County Park. Campers and day visitors should bring all food and water from Saratoga or the surrounding area before entering the park.
Saratoga's village center, a short drive down Highway 9, has a range of restaurants, a grocery store, and coffee shops. The town's dining scene tends toward casual American, Italian, and Asian options, with a few upscale restaurants near the historic downtown strip. Verify hours locally, as smaller establishments in the area can have variable schedules.
Practical Information
Contact and Information
Sanborn County Park is operated by Santa Clara County Parks. Current fees, hours, reservation links, and trail conditions are maintained on the official Santa Clara County Parks website. Verify all operational details there before your visit, as hours and fees change seasonally.
Restrooms
Flush restrooms and vault toilets are available at the campground and main day-use area. Facilities in more remote trail sections are limited.
Leave No Trace
The park follows Leave No Trace principles. Pack out all waste, stay on designated trails, and do not disturb vegetation or wildlife. Campfires may be subject to seasonal fire restrictions imposed by the county or the state — always check current fire conditions before your trip.
Accessibility
Some paved and compacted-surface paths near the main entrance area are accessible to visitors with mobility limitations. Most hiking trails are not wheelchair accessible due to natural terrain. Contact the park directly for current accessibility information.
Emergency Services
In a medical emergency, call 911. Cell service is unreliable inside the park; a companion or camp host can relay calls if needed. The nearest hospital facilities are in the San Jose or Los Gatos areas — confirm locations in advance.
Safety
The primary safety considerations at Sanborn are environmental. Trails can become slippery and muddy during and after winter rains, and some routes involve exposed sections with uneven footing. Check trail conditions with the park before visiting after heavy rainfall.
Mountain lions are present in the Santa Cruz Mountains. Sightings in the park are uncommon but documented. Follow standard precautions: hike with a companion when possible, keep children close, and do not run if you encounter one. The California Department of Fish and Wildlife publishes guidance on mountain lion encounters.
Poison oak is widespread along trails and forest edges throughout the park. Learn to identify it before your visit, stay on marked trails, and wash exposed skin promptly if contact occurs.
Fire danger is a serious concern in the dry season (roughly June through October). Respect any fire restrictions posted at the entrance, and never leave a campfire unattended.
