The Briones Reservoir Loop is a hidden gem in the East Bay hills that offers a quieter, more secluded hiking experience than many of the region’s better-known parks. This 13-mile loop winds around the scenic Briones Reservoir and features a diverse mix of landscapes from wide-open grassy ridgelines to cool, shaded oak and bay laurel forests. What makes this route particularly special is how remote it feels, especially along the northern shoreline, where visitors are few and the trail hugs the reedy banks of the reservoir in peaceful solitude.
