The Tassajara Ridge and Dougherty Valley Ridge Loop offers a dynamic mountain biking experience across rolling hills and open grasslands, with some wooded sections. You'll find yourself on a mix of doubletrack fire roads and singletrack, often sharing the path with grazing cows that can leave the terrain bumpy and rutted. Keep an eye out for panoramic vistas of Mount Diablo and the surrounding valleys from spots like the View from Hidden Valley Ridge, especially when the hills are green and wildflowers bloom in spring.
This moderate 20.2-mile (32.6 km) mountain biking route involves 1625 feet (495 metres) of elevation gain and typically takes about 2 hours and 32 minutes to complete. If you ride it clockwise, you'll get longer, more gradual downhills and shorter, steeper climbs. The best time to tackle this loop is during the spring and early summer to catch the most vibrant scenery.
Part of the Tassajara Creek Regional Park, this loop is a highly-rated trail known for its connection to a wider network. It's a great choice for mountain bikers with a good level of fitness, offering a challenging yet rewarding ride. The presence of cattle adds a unique, natural element to the trail, making it feel a bit wilder than some other local routes.
