SF Bay Trail (unpaved section)

Highlight (Segment) • Trail

This section of the SF Bay Trail is a combination of loose gravel and packed dirt/sand, and popular with many commuters from what I can tell. Dry weather conditions make this route fun, but probably best to take the roads on the more rainy days. Road cyclists will definitely wanna take the loose gravel portions slower. Gravel grinders, this route is for you!

No water refill stations along this segment that I could tell, but Baylands Park near the entrance offers facilities and watering options. Also beware of periodic closures due to trail maintenance.

San Tomas Aquino Creek

Highlight • River

The SF Bay Trail crosses over the San Tomas Aquino Creek, offering an option to pass under Highway 237. This section of the trail provides a scenic route with multiple paths for cyclists and hikers to explore. San Tomas Aquino Creek, a 16.5-mile stream flowing from El Sereno mountain through several cities before reaching the Guadalupe Slough. This creek has played an important role in historical land grant boundaries in the 1850s. While it has seen habitat changes, native fish species, such as rainbow trout, persist in the creek, and in 1996, a large Chinook salmon was seen.

The Coyote Creek and Guadalupe River converge in San Jose, where their waters flow into San Francisco Bay.

Guadalupe Slough

Highlight (Segment) • River

Pleasant wide gravel trail along the water. Keep an eye out for goathead thorns that can puncture most tires. Ideally use tires/tubes filled with sealant liquid. Carry repair kit and pump.

Sunnyvale East Channel

Highlight • River

Bikers on the SF Bay Trail can enjoy great views of the Sunnyvale East Channel, part of the extensive drainage and flood control network in the South Bay Area. The channel manages stormwater runoff and prevents flooding in nearby urban areas, draining into the San Francisco Bay. The trail is a peaceful spot to appreciate both nature and regional water management efforts.
