Lomas Cantadas summit - Los Venados & cut to Seaview trail

The Seaview and Big Springs Trail Loop offers a diverse and engaging jogging experience through Tilden Regional Park, blending shaded eucalyptus groves with expansive open hillsides. You'll navigate a mix of rocky singletrack and wider fire roads, with the landscape constantly shifting to keep your run interesting. Keep an eye out for the faint scent of eucalyptus in wooded patches and prepare for breathtaking vistas of the San Francisco Bay and Golden Gate Bridge from various viewpoints, including the Lomas Cantadas summit.

Planning your visit is straightforward, as the trail is located within the accessible Tilden Regional Park, often starting near amenities like the Quarry Picnic Site. While specific parking information isn't detailed, it's wise to arrive early, especially on weekends, to secure a spot. This route is also dog-friendly, allowing off-leash walking in most areas, so your furry companion can join you for the entire 6.9-mile (11.1 km) journey. Be sure to carry enough water, particularly during warmer months, as some sections are exposed.

This difficult 6.9-mile (11.1 km) loop, with its substantial 1220 feet (372 metres) of elevation gain and estimated 1 hour and 26 minutes duration, is a popular choice for its panoramic views and varied terrain. It's not just a standalone trail; sections of the Seaview Trail are part of the larger East Bay Skyline National Recreational Trail and the Bay Area Ridge Trail, highlighting its significance in the regional network. Beyond the views, Tilden Park is home to diverse wildlife, including coyotes and red-tailed hawks, offering a true natural escape close to urban areas.
