Updated May 10, 2026

If you've ever tried to plan jogging in Sierra Vista Open Space Preserve, you know how many routes there are and how overwhelming it can be to figure out which ones are genuinely worth your time. It's tough to tell the highlights from the filler when you're just looking at a map. That's exactly why we've put together this guide: our komoot community has explored, mapped, and reviewed these trails, so we've done the legwork to bring you a curated shortlist of the best.

Jogging here means embracing the diverse landscape of oak woodlands, rolling grasslands, and chaparral, all while enjoying sweeping views of the Santa Clara Valley and the San Francisco Bay Area. You'll find everything from easier paths to more demanding climbs, with elevations ranging from around 300 feet to 2000 feet. Just a heads-up: dogs and drones aren't permitted in the preserve, so plan accordingly.

For a challenging run with incredible payoff, we'd start with the Boccardo Loop Trail, a 4.7 miles (7.6 km) route that climbs almost 1,000 feet (300 m) and offers panoramic views. If you're looking for something a bit easier and family-friendly, the Penitencia Creek Trail is a fantastic 3.0 miles (4.9 km) option with varied terrain. With more than 200 runners having used komoot to explore these trails, you can trust you're in good company.

The Boccardo Loop Trail offers a rewarding jogging experience through the Sierra Vista Open Space Preserve, characterized by its open grassy hillsides and occasional oak woodlands. As you navigate the singletrack paths and switchbacks, you'll be treated to sweeping vistas of Silicon Valley and the San Francisco Bay, with the highlight being the panoramic views from Boccardo Peak. In spring, the hills burst with wildflowers and you might even spot cows grazing, adding to the scenic charm of this challenging route.

Planning your visit requires some consideration for this difficult 4.7-mile (7.6 km) loop, which involves 1061 feet (323 metres) of elevation gain and typically takes about 1 hour and 5 minutes. Shade is scarce, so carry ample water, especially during warmer periods. The trail can be muddy after rain, particularly on fire road sections. For a slightly less intense start, consider jogging the loop counterclockwise, which provides a more gradual initial ascent.

Beyond its scenic beauty, the Boccardo Loop Trail is a key part of a larger network, connecting to trails like the Bay Area Ridge Trail. Its accessibility from Alum Rock Park makes it a popular starting point for those looking to extend their run or explore more of the preserve. The ever-present, breathtaking views of the Bay Area serve as a significant draw, making this a favorite for joggers seeking a challenging workout with rewarding visual payoffs.

The Bay Area Ridge Trail: Sierra Vista and Calaveras Fault Loop offers a truly epic jogging experience, blending a rigorous workout with some of the best panoramic views in the region. You'll traverse diverse landscapes, from oak woodlands to rolling grasslands, with the terrain constantly changing underfoot. Keep an eye out for the stunning Sunset View from Calaveras Fault Trail, where the vistas stretch across the Santa Clara Valley and the entire Bay Area.

This difficult 9.2-mile (14.8 km) loop demands very good fitness, featuring a significant 2184 feet (666 metres) of elevation gain that will challenge your legs over its estimated 2 hours and 7 minutes duration. Be prepared for steep ascents and descents, and always check for current trail closures, as sections can be impacted by conditions. An early start is recommended to make the most of the views and avoid the heat on exposed sections.

What makes this one of the more popular trails and routes in the Sierra Vista Open Space Preserve is its unique combination of geological interest, running alongside the Calaveras Fault, and its connection to the larger Bay Area Ridge Trail system. It's an advanced jogging trail that provides a demanding course for those seeking a high-reward, high-effort adventure through varied ecosystems and dramatic scenery.

The Mineral Springs Grotto in Alum Rock Park tells the story of the area's geological history and abundance of natural mineral springs. Developed between 1891 and 1902, masons crafted intricate stone grottoes using native rock to protect the springs: sulfur, magnesia, iron, and carbonated soda springs. These springs once supported a thriving health resort, with waters believed to have medicinal properties. Today park visitors can explore the grottoes and interpretive panels along the Creek Trail to learn about the springs’ historical significance and the park’s transformation from an ancient ocean beach to the stunning canyon seen today. Unfortunately, soaking is not allowed these days.

It's really amazing that this stone bridge is still here. I understand it was originally built to easily get pack horses across the creek — and of course the people with them, too.

Inspiration Point in Alum Rock Park offers stunning views of San Jose and the Bay and is surrounded by mature native trees and shrubs. Since 2011, volunteers have been working to restore the area by removing invasive species through the "Weed & Walk" group. Shade can be found up here amongst the trees, and there is a wooden fence and wooden benches indicating the arrival of the Inspiration Point viewpoint.

You can find free parking and restrooms by the side of the creek. From here you have the option of many different hilly but nontechnical trails up to Eagle Rock, Inspiration Point, Boccardo, or along the creek side.

This trail can be ridden in either direction and plays out similarly no matter how you ride it. A short, switchbacky climb is rewarded with a fun twisty descent. If you need a rest after the climb there's a shady place to stop at the top of the hill.
