Los Trancos Open Space Preserve — Attraction in Palo Alto

Los Trancos Open Space Preserve is one of those places that surprises you with its quiet charm. Tucked away off Page Mill Road in the Santa Cruz Mountains, it offers peaceful trails, sweeping views, and an unexpectedly fascinating look at California’s geology. The preserve isn’t crowded, which makes it ideal for a serene solo hike or a contemplative walk through oak woodlands and shady glens.

The star attraction here is the San Andreas Fault Trail, a short, well-marked 1.5-mile loop that’s equal parts hike and geology lesson. Signs along the way explain how the infamous fault line has shaped (and literally shifted) the landscape over time. There are examples of offset fences and terrain displacement from past earthquakes, and it’s all laid out in a way that’s accessible without being overly technical. Kids and adults alike will find it fascinating.

Beyond the fault trail, you can connect to a network of longer hikes that pass through varied terrain: open grassy ridges, dense forest, and trickling seasonal creeks. The Lost Creek Loop and Franciscan Loop are great for those wanting to extend their time in nature, and the preserve connects to Monte Bello and Foothills Park if you’re looking to push into longer day hikes. Trails are well-maintained, signage is clear, and the elevation gain is manageable for most.

There’s no water on-site and very limited parking (maybe 20+ spots), so it’s best to arrive early on weekends. No dogs or bikes are allowed, which helps maintain the peaceful vibe and keeps the focus on hiking and wildlife. You might spot deer, wild turkeys, and lots of birds if...

What a nice place for a short gentle hike. I took the San Andreas Fault trail and it was easy and educational. This trail has minor elevation gain and loss, so even people who are not hikers can enjoy seeing the San Andreas fault. There are wildflowers here as well and a few good views. The trail is mostly in shade and in a canyon area, so views are a little limited, but it is still scenic and pretty. Obviously, there are many more trails and views in the rest of the park. This trail was only 1.1 miles, but there are other, longer trails here. Parking is good, and the information board is good and has trail maps for you. There is a bathroom across the street. There is no water, so bring plenty. Cell phone coverage is spotty on the trail. The drive up is scenic and you will see many huge mansions. Go and enjoy a day out, but wear insect repellent because there are ticks here....

Best known for its Earthquake Trail, the Los Trancos Open Preserve is nestled into the hills above Los Altos around 45 miles south of San Francsico. Be sure to pick up a map at the trailhead to clue you in on the subtle changes in landscape, indicating one of the most notorious and active geological fault in the world.

Starting in open surroundings with great views of the bay, San Bruno Mountain and on a clear day even Loma Prieta, the trail heads into woodland where you'll spend most of the hike. Weather is usually better here than you’ll find at the northern end of the peninsula, so although this is a worthwhile hike on its own, it's also a safe alternative hike should you get fogged...
