|
73+ Acres Big Canyon + Eaton Combined |
1.2 Miles Big Canyon’s Main Trail |
366 Acres Pulgas Ridge, Regional Connection |
2007 Hillside Trails Plan Adopted |
San Carlos’s western hills hold a genuinely connected trail network, not just a single isolated park, and understanding how the pieces link together helps explain why hillside living here appeals to so many outdoor-minded buyers.
Big Canyon Park: A Real Workout Close to Home
Big Canyon Park sits at 3200 Brittan Avenue, and the city itself describes its centerpiece 1.2-mile trail as genuinely challenging, with real elevation gain that rewards hikers with sweeping views of San Carlos, the San Francisco Bay, and on clear days, out toward the East Bay hills. Regular visitors on hiking apps consistently praise it as a fast, heart-pumping workout tucked directly into a residential neighborhood, though they also note there are no restroom facilities on site, so plan accordingly.
Eaton Park: The Direct Trail Connection
Directly across Brittan Avenue from Big Canyon’s entrance sits the trailhead into Eaton Park, letting hikers link both parks into a single, longer outing without ever getting in a car. Together, Big Canyon and Eaton Parks offer more than 73 acres of natural open space, with trailheads, directional signage, and entrance kiosks with trail maps added citywide as part of a 2017 Trail Wayfinding Project.
A Real, Adopted Plan to Connect Further
San Carlos’s Trails Connections Plan, adopted by City Council in February 2007 following years of community input, identified and prioritized 14 possible connections linking the city’s local trail system to neighboring regional open space, including Pulgas Ridge Open Space Preserve and trails within the City of Belmont. This wasn’t a one-time study; it’s the actual planning document the city continues to reference for trail improvements.
Beyond the City Line: Pulgas Ridge and Edgewood Park
For hikers wanting more mileage, Pulgas Ridge Open Space Preserve sits just beyond San Carlos, offering 366 acres and six miles of trails, including a dog-friendly off-leash area and ridge-top bay views. Further along, Edgewood Park and Natural Preserve adds 467 acres and ten miles of trails, genuinely famous each spring for its wildflower displays across serpentine grasslands, with easy access from Interstate 280.
Other Trail Access Points Worth Knowing
| North Crestview and Vista Parks offer additional hillside trail access beyond Big Canyon and Eaton |
| Arguello Park in Cordes adds shorter trails alongside its 21 acres of playgrounds and sports facilities |
| Heather Dog Park offers a shorter trail option for owners walking dogs |
| Watch for poison oak along less-maintained sections; long sleeves and pants are a genuine local recommendation |
Key Takeaway
San Carlos’s western hills offer a genuinely connected trail system, not an isolated park, linking Big Canyon directly to Eaton Park and, through the city’s own adopted trails plan, out toward Pulgas Ridge and Belmont’s own trail network.
