Miwok & Manzanita Trail loop

The trails in Round Valley, including the Miwok Trail, are primarily fire roads. While generally easy, they feature some short, steep climbs. The route requires average riding skills and above-average cardio fitness due to these steep sections. Expect surfaces that can be soft, dusty, or muddy, especially with frequent equestrian use and grazing cattle. The loop has an elevation gain of around 550 meters.

You'll ride through beautiful oak woodlands and rolling hills, particularly vibrant during the green season in spring. Keep an eye out for historic farm equipment and grazing cows. The preserve offers views of Mount Diablo and opportunities for birdwatching, including raptors like golden eagles and redtail hawks. Wildflowers are abundant in spring, especially along the single-track paths that parallel the main Miwok Trail.

Spring is ideal, especially during the 'green season,' when the hills are lush and wildflowers are in bloom. However, the trails can be ridden year-round, though conditions might be dusty in summer or muddy after heavy rains.

One of the most notable aspects is the solitude it offers; you'll often encounter very few other people. The preserve's remote location, being closer to the Central Valley, contributes to this quiet atmosphere. There's also flexibility in the trail system, allowing for various loop configurations, and often smaller, parallel single-track paths that offer more shade and a closer experience with wildflowers.

While the trails are generally easy, the loop includes some short, steep climbs that require above-average cardio fitness. It's best suited for riders with at least average mountain biking skills and good fitness rather than absolute beginners.
