If you've ever tried to plan road cycling in Calero County Park, you know how quickly the options can feel overwhelming. Sifting through countless routes to find the ones genuinely worth your time and effort can be a real headache. That's where we come in: our komoot community has ridden, reviewed, and curated the best routes, saving you the guesswork and pointing you straight to the highlights.

Road cycling here means embracing the eastern foothills of the Santa Cruz Mountains, where you'll find a beautiful mix of California Oak woodlands, chaparral, and rolling grassland hills.

Expect everything from moderate loops to challenging climbs, with the landscape particularly vibrant with wildflowers from March to May.

If you only do one route, we'd start with the Calero County Park to Uvas Canyon County Park loop, a fantastic 39.7 miles (63.9 km) ride that delivers scenic lake views and rolling terrain. For those seeking a bigger challenge and substantial elevation gain, the Calero County Park to Uvas Reservoir loop is a top favorite at 55.1 miles (88.7 km).
