Best bike routes in San Jose (California)

San Jose gets written off as a place you drive through. Silicon Valley sprawl, office parks, ten lanes of expressway.

Look closer and the picture changes. This is a city that treats bike trails like infrastructure. A network of paved creek paths runs under the traffic, connecting downtown to the Bay without a single stoplight for miles. And on its eastern edge sits the tallest mountain in the entire Bay Area, with the most popular road climb in the county winding up its flank.

Flat commuter paths on one side, a 4,300 foot monster on the other. Here is how to ride both.

The creek trails: San Jose's car free network

The smartest thing about riding San Jose is that the rivers do the routing for you. The city built its trail network along its creeks, which means long, flat, paved miles with no cars to negotiate.

Guadalupe River Trail

The backbone of the system. The Guadalupe River Trail is currently developed as two disconnected sections: a 9-mile northern/central stretch from Alviso to Downtown San Jose, plus a 2.4-mile southern section in the Almaden area along its namesake river, and its main stretch connects Downtown San Jose all the way north to Alviso and the edge of San Francisco Bay. It is paved, mostly grade separated, heavily used by commuters, and was designated a National Recreation Trail in 2009. One honest note: the trail is currently built as two disconnected segments, with a shorter southern piece in Almaden Valley, and its underpasses can flood after storms. Check current conditions on the city's trail page before counting on a clean run.

Los Gatos Creek Trail

The prettiest ride in the network. The Los Gatos Creek Trail runs about 10 miles from San Jose through Campbell to the town of Los Gatos, finishing at Lexington Reservoir in the hills. It follows the creek the whole way, past parks and shaded stretches, and the final climb up to the dam gives an otherwise flat ride a proper ending. If you only ride one trail in San Jose, make it this one.

Coyote Creek Parkway

The long one. The Coyote Creek Parkway is a paved 15 mile trail flowing south from Hellyer County Park to Anderson Lake in Morgan Hill, through wetlands, oak canopy, and open country that stops feeling like a city surprisingly fast. Flat, quiet, and ideal for a steady endurance day. Families ride the northern stretches; stronger riders take it end to end and back.

The climb that owns the county

East of the city, the riding changes completely.

Mount Hamilton

Mount Hamilton is the tallest peak in the Bay Area, and the ride up Mt. Hamilton Road to the Lick Observatory at the summit is the most popular climb in Santa Clara County. The classic west approach is about 18.4 miles of climbing with around 4,300 feet of gain, broken up by two short descents along the way.

Here is the detail that makes it special. The road was built between 1876 and 1887 so that mule drawn wagons could haul telescope parts to the top, which means the grade stays gentle the whole way, averaging around 4 to 6 percent through hundreds of switchbacks. It never breaks your legs with a wall. It just never, ever stops. Bring more water than you think you need, because summer out here gets seriously hot and the road is exposed, and there is nothing to refill until the observatory itself.

The reward is one of the great summits in American cycling: the world's first permanently occupied mountaintop observatory, with Silicon Valley laid out on one side and the empty folds of the Diablo Range on the other. If San Jose has a bucket list ride, this is it.

Where San Jose gets dirty

You do not have to leave the city limits for real mountain biking.

Santa Teresa County Park

Ten miles south of downtown, Santa Teresa County Park packs over 17 miles of unpaved trails into 1,673 acres of hills above the Almaden Valley. The names locals trade are Rocky Ridge and Stile Ranch: genuine rock gardens, tight switchbacks, and technical lines that reward a rider with skills, plus the fire road grind up Coyote Peak for a full 360 view of the South Bay.

Two things to know before you go. The soil here is heavy clay, so the park closes to riding when it is wet, and trails stay sticky after even light rain. And in summer the hills run hot and exposed. Check the county's trail status before driving out, and go early.

Sierra Vista and Alum Rock

On the east side, the Sierra Vista Open Space Preserve above Alum Rock Park offers miles of multi use trails through open grassland, with big views back over the valley. Little shade, honest climbing, and far fewer riders than the trails deserve.

What this valley does to a bike

San Jose riding swings between two extremes, and both wear on your equipment in their own way.

The creek trails mean weekday miles in all conditions, with winter puddles and grit that never quite dry out under the overpasses. A mud guard keeps the spray down when the paths are wet. The long, exposed miles up Mount Hamilton put hours of load through your hands, where quality bar tape earns its keep. And the rock gardens at Santa Teresa are exactly the kind of terrain that chips paint and batters frames, which is where frame protection and a set of proper MTB grips stop being accessories and start being part of the setup.

None of it pedals for you. It just means the bike is ready for whichever San Jose you choose that day.

The truth about riding San Jose

This city hides its riding in plain sight. The commuters know the creek trails. The climbers know Hamilton. The locals know Santa Teresa.

Put the three together and you get something few cities can match: a car free network, the biggest climb in the Bay Area, and real dirt, all inside one county.

Pick your San Jose. Then come back for the other two.
