The Briones Reservoir area offers a demanding touring cycling experience, winding through the diverse landscapes of Briones Regional Park. While the immediate reservoir loop is reserved for hikers, this route provides a challenging 39.8-mile (64.0 km) ride with 3017 feet (920 metres) of elevation gain, taking approximately 4 hours and 15 minutes. You'll encounter rolling hills, fire roads, and steep climbs, all while enjoying panoramic views of the reservoir, the East Bay hills, and on clear days, even Mount Diablo. The scenery shifts from open, grassy hillsides, vibrant with wildflowers in spring, to shaded oak and bay laurel woodlands, making it a rewarding, albeit difficult, journey for experienced cyclists.
Planning your visit requires careful attention to local regulations; an EBMUD permit is mandatory for accessing trails directly around the reservoir, even for hikers. For this cycling route, be prepared for varied terrain, as some sections within the park can be unpaved and challenging. Spring is an excellent time to witness the wildflowers, but be mindful that some areas can become very muddy after rain, particularly between the dam and the Hampton Trail. Always check conditions before you go.
This route is a fantastic option for cyclists seeking advanced cycling trails near Briones Reservoir, offering a significant test of endurance and fitness. The area is known for its challenging climbs, including segments of Bear Creek Road, which are popular with local road cyclists. Despite the restrictions on the direct reservoir loop, the broader park provides a rich ecosystem of grasslands and woodlands, offering a remote and quiet feel in many sections. It's a great way to experience the East Bay's natural beauty on two wheels, provided you're up for the challenge.

Embark on the Iron Horse Trail and Dougherty Valley Loop for a touring cycling experience that transitions from the smooth, wide paths of a former railway to the gentle undulations of the San Ramon Valley. This moderate 41.0-mile (66.0 km) route, with 1206 feet (368 metres) of elevation gain, takes about 3 hours and 54 minutes, offering a pleasant blend of urban and natural scenery. You'll enjoy shaded sections, open creekside views, and glimpses of Mount Diablo, making it a great option for a longer, comfortable ride.
Planning your ride is straightforward, as the Iron Horse Trail is well-maintained and connects various communities, including BART stations, making public transport an option. The route is popular, so expect company, especially near town centers. Spring and early summer are ideal for this loop, when the Dougherty Valley might surprise you with vibrant wildflowers and the weather is generally mild.
What sets this route apart is its combination of the pancake-flat Iron Horse Trail, a former railroad right-of-way, with the more varied terrain of the Dougherty Valley. Keep an eye out for the unique Golf Ball Protection Tunnel near the San Ramon Country Club. This trail is a fantastic choice if you're looking for a substantial touring cycling route that's mostly paved and accessible for a wide range of fitness levels.
