Updated May 29, 2026

If you've ever tried to plan jogging around Saranap, you know how quickly the options can feel overwhelming. With so many trails crisscrossing the area, it's tough to know which routes are genuinely worth your time and effort, and which are just filler. That's where we come in. Our komoot community has mapped, run, and reviewed these routes, so we've curated a shortlist of the absolute best, saving you the guesswork.

Jogging around Saranap offers a fantastic mix of terrain, from the rolling hills and valleys to unique sandstone formations and even surprising redwood trees in local canyons. You'll find everything from smooth, paved paths perfect for a steady pace to more rugged natural trails that climb through regional parks like Tilden and Wildcat Canyon, often with views of Mount Diablo. Good news for planning: many of the popular routes, like the Iron Horse Trail, offer multiple access points and free parking, making it easy to jump on and go.

If you only do one route, we'd point you straight to the Iron Horse Regional Trail. At 11.8 miles (19.0 km), it offers a challenging and varied experience that truly showcases the area. For a slightly shorter, yet still incredibly scenic run, the Lamorinda Trail Loop, at 5.8 miles (9.3 km), is a local favorite that delivers big on views for a moderate effort. With more than 700 runners having already explored Saranap with komoot, you're in good company.

Iron Horse Regional Trail

If you're looking for a long, consistent run with varied scenery, the Iron Horse Regional Trail is a solid pick. This 11.8 miles (19.0 km) route, with a mere 230 feet (70 metres) of elevation gain, is officially rated difficult, but its smooth, paved surface and gentle grade make it feel much easier for joggers, taking about 1 hour and 57 minutes to complete. You'll jog past marshy creeks like Walnut Creek, catch glimpses of distant hills including Mt. Diablo, and weave through charming towns like Danville, enjoying a blend of natural and community views.

This trail is incredibly accessible, connecting directly to BART stations such as Dublin/Pleasanton and Pleasant Hill, which is a huge plus for public transportation users. You'll find plenty of amenities along the way, including water stations, restrooms, and benches, especially when passing through the towns it links. It's a great option year-round, but early mornings or late afternoons are often best to avoid the midday sun, as shade can be intermittent.

The Iron Horse Regional Trail is a fantastic example of a successful rail-trail conversion, built on the former Southern Pacific Railroad right-of-way established in 1891. This history is precisely why it boasts such a characteristic flat and direct path, making it one of the longest rail-trails in California. It serves as both a recreational path and a commuter corridor, linking residential and commercial areas, schools, and public transport across multiple cities.

The Lamorinda Trail Loop offers a pleasant and varied jogging experience, winding through the East Bay cities of Lafayette, Moraga, and Orinda. You'll find yourself on 100% paved surfaces for the majority of the route, enjoying views of green hills, occasional wildflowers, and even grazing cattle in areas like the Lafayette-Moraga Regional Trail. The central section, following a historic railroad route, is particularly scenic, blending urban edges with natural landscapes.

This moderate 5.8-mile (9.3 km) route, with 353 feet (107 metres) of elevation gain, typically takes about 59 minutes to jog. It's suitable for various skill levels, though the three medium-sized hills do add a noticeable challenge, so come prepared for some effort. You can begin your journey from any of the three connected communities, and local maps are often available at BART stations and community centers to help you navigate.

What truly sets this trail apart is its continuous nature, seamlessly linking Lafayette, Moraga, and Orinda, offering a unique way to explore the region. Much of the path follows a former rail line, providing a dedicated and often traffic-separated experience. This historical conversion into a paved trail makes it one of the best running routes in Lamorinda for consistent, engaging workouts.

The Las Trampas Creek presented a formidable obstacle to the old railroad that today is the Lafayette-Moraga bike trail, which caused this interesting and scenic loop.

Along this section of the former railway the irons horses have come and gone, but the real horses are still here. Since it was turned into a fantastic car-free trail through the Las Trampas valley the horses are not always behind fences, they often graze along the trail, keeping the grass short along the off-pavement parallel runners trail ;-)
