Lost Trail is a quiet Portola Valley ridge walk with rolling grasslands, scattered oaks and sweeping Bay Area vistas — ideal for wide landscape and seasonal wildflower shots. Best light is golden hour at sunrise or sunset from the higher ridge points; spring brings explosive blooms after rain. Trail is unpaved and uneven but short; no entry fee, limited roadside parking at the trailhead, and expect neighbors and dog walkers. Weekdays and early mornings are least crowded.
