Best overall pick
Rancho San Antonio Open Space Preserve
Foothills Between Los Altos And Cupertino • Large Open Space Preserve With Valley And Ridge Trails • Local Favorite For Varied Routes
A sprawling network of trails where you can choose anything from a flat stroll to a lung-busting climb on the PG&E or Wildcat routes.[1][5]
Rancho San Antonio is the default answer when locals are asked where to hike nearby, thanks to its mix of shady canyon paths, open ridgelines, and easy access from town.[1] Start with the Deer Hollow Farm area for a relaxed introduction, then work up to longer loops that link the PG&E Trail or Wildcat Canyon for big views over the South Bay.[1][4] Parking fills early on weekends, so aim for a morning start if you want a calmer experience.
02
Best for families
Hidden Villa
Los Altos Hills Along Moody Road • Working Farm And Nature Preserve With Signed Trails • Best For Families And Newer Hikers
A low-key network of farm-adjacent trails that blend kid-friendly exploring with quick escapes into oak woodland.[3]
Hidden Villa is a nonprofit farm and wilderness property where trailheads sit just beyond barns, gardens, and pastures, making it an easy sell for kids and visiting friends.[3] Well-marked paths range from gentle creekside ambles to steeper hillside loops, so you can dial up or down the effort without driving far into the mountains.[3][5] Check seasonal hours and any reservation requirements before you go, and budget a little extra time to wander the farmyard before or after your hike.

Best mellow sunset walk
Pearson-Arastradero Preserve
East Of Los Altos Hills Off Page Mill Road • Rolling Grassland And Oak-Studded Preserve • Best For Relaxed Loops And Golden-Hour Views
Gently rolling trails weave through open hills and small ponds, ideal for an after-work loop or easy weekend wander.[2][5]
Just over the ridge from Los Altos Hills, Arastradero offers wide, mostly non-technical trails that suit walkers, casual hikers, and mixed-ability groups.[2] Spring brings carpets of wildflowers, while late-day light in summer and fall turns the grasslands a deep gold, with views stretching across the valley.[2][5] Stick to the signed loops to keep things simple, or link a few segments for a longer circuit without adding much extra climbing.
04
Best view-packed ridge hike
Windy Hill Open Space Preserve
Ridge Above Portola Valley • Ridge-To-Valley Preserve With Big Bay Vistas • Best For Wide-Open Views
A classic climb from grassy lower slopes to a breezy ridgeline where the entire South Bay spreads out below you.[2][5]
Windy Hill is a go-to when you want a real sense of being in the mountains without an all-day drive, offering trails that rise quickly from Portola Valley up to the open crest of the Santa Cruz range.[2] The popular Spring Ridge and Hamm’s Gulch combinations serve up a satisfying mix of shaded forest, switchbacks, and expansive Bay views that feel especially dramatic on clear winter days.[2][5] Expect some wind on the upper slopes—as the name promises—and bring layers even when it’s warm in town.
05
Best workout climb
Black Mountain via Rhus Ridge Trail
Upper Moody Road Trailhead In Los Altos Hills • Steep Summit Route Through Chaparral And Open Ridges • Best For Strong Hikers Seeking A Challenge
A stout, view-filled ascent from Los Altos Hills up to the 2,800-foot summit of Black Mountain on linked ridge trails.[4][5]
Starting from the Rhus Ridge trailhead above Moody Road, this route wastes no time gaining elevation as it threads through oak woodland and chaparral toward the skyline.[4] The climb is sustained but rewarding, with long views opening toward the South Bay and, on clear days, out to Mount Diablo and beyond.[4][5] Go early on warm days—shade is limited on the upper stretches—and pack plenty of water, since services and facilities are minimal once you leave the trailhead.
