01
Best overall pick
Rancho San Antonio County Park & Open Space Preserve
Foothills Above Los Altos • Busy Regional Preserve With Varied Terrain • Go-To Choice For All Levels
A huge network of hillside trails ranging from flat ranch roads to steeper climbs, just a short hop from Loyola.
Start from the main entrance for mellow farm and creekside paths, or head up the Wildcat Canyon and High Meadow routes for real elevation and big views over the Bay.[4] Shady oak woodlands, open grass slopes, and frequent wildlife sightings make it easy to build anything from a 30-minute walk to a solid half-day hike.
02
Best for ridge-top scenery
Monte Bello Open Space Preserve
Skyline Boulevard Ridge • Ridgetop Open-Space Preserve • Best For Long View Hikes
High, rolling ridges and the climb to Black Mountain deliver classic Santa Cruz Mountains scenery.
From the Skyline lot, you can link Canyon, Bella Vista, and Indian Creek trails into satisfying loops that stay mostly on cool, north-facing slopes.[3] Strong hikers often continue to the summit of Black Mountain for wide-open panoramas stretching from Mt. Hamilton to the Pacific on clear days.[3] The open grasslands can be windy and exposed, so plan for sun and stronger breezes than in town.
03
Quietest escape close by
Los Trancos Open Space Preserve
Above Palo Alto Along Skyline • Quiet Forested Preserve • Best For Peaceful Loops
Short, gently rolling loops through mixed forest with a tucked-away, almost forgotten feel.
Los Trancos is a smart choice when better-known preserves feel crowded, offering narrow singletrack through bay, oak, and fir forest not far from Loyola.[3] The main loop is modest in distance but has enough ups and downs to feel like real exercise, and the shaded ravines stay pleasantly cool on warm days.[3] Trail junctions are well signed, so you can wander a bit without worrying about getting truly turned around.
04
Best workout hike
Windy Hill Open Space Preserve
Portola Valley • Open Grassland And Ridge Preserve • Top Pick For Big Climbs And Vistas
A steep grind from valley floor to skyline ridge with constant views back over Portola Valley and the South Bay.
Starting from the lower parking area, the trails climb quickly through oak woodland to open, breeze-swept hillsides that live up to the preserve's name. Stronger hikers can link Spring Ridge and Hamms Gulch trails into a strenuous loop with far-reaching views in multiple directions. On clear winter days you can sometimes pick out downtown San Jose, the Bay, and even distant Diablo Range peaks.
05
Best family-friendly wander
Hidden Villa
Los Altos Hills Backroads • Working Farm With Creekside Trails • Easygoing Option Close To Home
Short, shady creek and hillside paths paired with a historic farm and educational center.
Hidden Villa's modest trail network is ideal for younger hikers or relaxed days when you still want a taste of the foothills without a long drive. You can follow Adobe Creek under tall sycamores, climb briefly onto surrounding slopes for small viewpoints, then loop back through the farm area to visit animals or picnic in the meadow. Parking can fill on nice weekends and access sometimes requires a reservation, so it is worth checking ahead.
