Pearson-Arastradero Preserve offers a nice mix of rolling grassland and evergreen forest just off Highway 280 in Palo Alto, making it easy to reach if you’re anywhere on the Peninsula. The preserve climbs from 275 feet in the northeast section up to 775 feet in the southwest, so you’ll get some elevation change as you explore.
The main loop is 3.7 miles at a moderate pace, and because the terrain varies so much, different sections feel pretty distinct from each other. Some parts take you through quiet grassland where you can see across the valley, while other trails wind through shaded forest that’s nice on warmer days. There’s also a lake area where you can stop and let your dog rest.
Wildlife sightings aren’t rare here. We saw deer on our last visit, and the preserve is also home to bobcats and coyotes (which you probably won’t encounter, but it’s good to know). Bird watchers find plenty to look at year-round. The mix of habitats—grassland, oak woodland, and areas with larger evergreens—means you’ll see different species depending on which trail sections you choose.
Dogs need to stay on leash throughout, which makes sense given the wildlife and the fact that horses and bikes also use these trails. The preserve stays open to hikers, leashed dogs, equestrians, and bicyclists, so you might share the trail with any combination of those. Early morning or weekday visits tend to be less crowded if you prefer quieter hiking.
The elevation gain is spread out over the full loop rather than being steep in one section, so most dogs handle it well. Bring water since there’s no reliable source along the trails, and watch for poison oak in the overgrown areas, especially in summer. The bay views from higher sections are worth the climb.
