Tilden Regional Park

The Seaview and Big Springs Trail Loop offers a diverse jogging experience, taking you through shaded eucalyptus groves and open hillsides within Tilden Regional Park. You'll encounter a mix of fire roads and winding single-track paths, with some rocky stretches demanding careful footing. From various vantage points, you can enjoy expansive views of the San Francisco skyline and the Golden Gate Bridge, making the challenging sections well worth the effort.

This difficult 6.2-mile (10.0 km) route involves a substantial 1167 feet (356 metres) of elevation gain, typically taking about 1 hour and 19 minutes to complete. Many joggers start near the Quarry Picnic Site, where amenities like restrooms are often available. Be sure to carry plenty of water, especially on warmer days, as the uphill sections can be quite a sweat session.

Beyond the workout, this trail is renowned for its stunning views from atop a scenic ridge, offering a unique perspective of both urban landmarks and natural landscapes. It's also part of the larger East Bay Skyline National Recreational Trail, connecting you to a network of other parks and adventures. Keep an eye out for wildlife like coyotes and red-tailed hawks.
