Overview
Foothills Park is a roughly 1,400-acre open space preserve situated in the hills west of Palo Alto, California, at the edge of the Santa Cruz Mountains. It sits within unincorporated Santa Clara County and is administered by the City of Palo Alto. The landscape combines rolling grasslands, coast live oak woodland, chaparral, and seasonal creeks, creating a habitat mosaic that supports a wide variety of native plants and wildlife.
For decades, Foothills Park operated under a long-standing residency restriction that limited access to Palo Alto residents and their guests — a policy that drew significant public debate. Access rules have changed; verify current admission eligibility directly with the City of Palo Alto Parks & Recreation department before visiting, as policies may continue to evolve.
Because the park is intentionally managed at low visitor capacity to protect its ecology, it retains a quieter, less developed character than many Bay Area regional parks. Facilities are modest: picnic areas, restrooms, and a network of hiking trails. There are no lodging options, restaurants, or retail within the park itself.
Before You Go
Access and Permits
Visit the City of Palo Alto's official parks website to confirm current access policies, required permits or reservations, and any fees before your trip. Access rules have historically been unusual for a California public park, so do not assume walk-in entry is guaranteed.
What to Bring
- Adequate water — no water fountains are guaranteed to be operational on all trails
- Sun protection: many trail sections cross exposed grassland with little shade
- A trail map downloaded in advance; cell signal can be unreliable in the hills
- Layers: marine fog can roll in from the coast and drop temperatures quickly, even in summer
Dogs and Bikes
Verify the current rules for dogs and bicycles with park staff; regulations for this preserve have historically been more restrictive than regional parks in Santa Clara County.
Getting There
Foothills Park is accessible by car via Page Mill Road, which winds into the hills from the Palo Alto flat lands. The park entrance is located on Page Mill Road; confirm the exact address on the official site, as GPS routing on Page Mill Road can occasionally misdirect visitors.
Public transit options to the park entrance itself are limited. The closest major transit hubs are in downtown Palo Alto, served by Caltrain (Peninsula rail corridor) and several Santa Clara Valley Transportation Authority (VTA) bus routes. From those hubs, reaching the park entrance without a car requires a significant uphill distance — check current VTA and SamTrans routes for any services on Page Mill Road before assuming you can arrive car-free.
Parking is available in the park's lot. Capacity is limited, which reinforces the low-impact management philosophy. Arrive early on weekends and spring weekdays.
Getting Around
All movement within Foothills Park is on foot along a network of dirt and gravel trails. The terrain ranges from gentle valley paths to steeper hillside routes with moderate elevation gain. Trails are generally well-signed but carry a downloaded map or the park's printed trail guide as a backup.
The Arastradero Lake area (in the adjacent Arastradero Preserve, a separate but nearby facility) is sometimes confused with Foothills Park — confirm which preserve you are navigating before setting out. Within Foothills Park itself, Charquin Trail, Indian Creek Trail, and several loop combinations are among the options; verify current trail names and conditions with park staff, as trail work occasionally closes sections seasonally.
Things to See & Do
Hiking
Hiking is the primary activity. Trails range from easy lakeside walks to moderately strenuous ridge routes with views toward San Francisco Bay and, on clear days, the distant Diablo Range. Spring wildflower displays — including California poppy, lupine, and owl's clover in good rainfall years — are a highlight.
Wildlife Observation
The oak woodlands host acorn woodpeckers, western scrub jays, and various raptors. Mule deer are commonly seen, particularly in early morning and late afternoon. The preserve also provides habitat for occasional mountain lion activity; heed any posted wildlife alerts.
Picnicking
Designated picnic areas offer a peaceful setting amid oaks. The park's low crowds compared to regional parks in the area make it a genuinely relaxing spot for an outdoor lunch.
Nature Photography
The combination of golden grasslands, gnarled oaks, and seasonal creek corridors provides strong photographic subjects across seasons. Morning light on the hills is particularly appealing.
Food & Drink
There are no food vendors, cafés, or restaurants inside Foothills Park. Pack everything you need before arriving — including water, snacks, and a full meal if you plan a long day.
The nearest dining options are in Palo Alto, particularly along California Avenue and University Avenue, which offer a wide range of cuisines from casual to upscale. El Camino Real and the broader Palo Alto and Los Altos area also have grocery stores and cafés convenient for assembling a picnic before heading to the park.
Practical Information
Emergency Contacts
In an emergency within the park, call 911. Cell signal can be weak in the hills — note your trail location and the park entrance address before heading out. The Santa Clara County Sheriff and Palo Alto Police Department share jurisdiction depending on location; park staff can clarify.
Restrooms
Restroom facilities exist at the park entrance and some trailheads. Availability and condition should be confirmed at the entrance on arrival.
Fees
Verify current entrance fees, if any, on the City of Palo Alto's official parks page. Fee structures have changed in recent years alongside access policy changes.
Accessibility
Some flat sections near the park entrance may be accessible to visitors with limited mobility, but most trails involve uneven terrain. Contact the parks department in advance to discuss accessible route options.
Safety
Mountain lions are present in the Santa Cruz Mountain foothills. Read and follow all posted wildlife safety guidelines. Do not hike alone in remote sections, keep children close, and know how to respond to a mountain lion encounter (face the animal, do not run, make yourself appear large).
Tick exposure is a genuine concern in grassland and oak woodland habitats throughout the Bay Area foothills. Wear long pants, use insect repellent approved for ticks, and perform a full body check after your visit. Lyme disease and other tick-borne illnesses are present in this region.
Trail conditions change seasonally. After significant rain, trails may be muddy or closed to prevent erosion. During fire weather, the park may close entirely. Check for any closures or fire danger alerts through the City of Palo Alto or CAL FIRE before visiting in summer or fall.
