Round Valley Regional Preserve Trails Professional Guide
Detailed Trail Description from our Guidebook
"Loop through this preserve, which forms an important link in the East Bay’s open space chain, using the Hardy Canyon and Miwok trails. The rolling, oakshaded hills here are daubed with floral colors in spring, and the impressive expanse of Round Valley itself has few rivals in the Bay Area. This is a popular equestrian area, and the single-track Hardy Canyon Trail takes a beating. Follow a path that curves left from the trailhead to a T-junction with a dirt road. Turn right and go across a bridge over Marsh Creek. The Miwok Trail, which you will use later, is right, but you turn left on the Hardy Canyon Trail and stroll beside Marsh Creek. Staying right at a fork, you follow a rutted track through an open field and curve away from the creek. Among the trees found in this preserve are California buckeye, valley oak, blue oak, coast live oak, Fremont cottonwood, hoptree, Western sycamore, and California bay. The trail rises through a blue oak savanna and then enters the canyon holding High Creek."
