Four Corners-Old Ranch Loop

Trail Overview

Four Corners-Old Ranch Loop is a beginner-friendly ATV and dirt bike trail in Hollister Hills SVRA that offers a manageable introduction to California's Diablo Range foothill terrain while still keeping intermediate riders engaged. This designated OHV loop winds through gently rolling hills on primarily hard-packed dirt, with intermittent sections of loose soil, small rocks, and shallow ruts that reflect the park's well-used but maintained trail system. The route is clearly signed and follows a one-way design typical of Hollister Hills, helping guide traffic flow while still requiring attention at intersections where trails converge. Elevation changes are mild but consistent enough to introduce new riders to throttle control and line choice, and the overall mileage makes it suitable for shorter sessions or as part of a larger network ride within the SVRA. As part of a state-managed recreation area overseen by California State Parks' OHMVR Division, the trail is generally open year-round, though temporary closures can occur during or after wet weather to protect trail conditions and reduce erosion. Summer riding brings dry, dusty conditions that can significantly limit visibility, especially on busier weekends when mixed skill levels share the same system. Riders should expect occasional blind corners and rolling terrain that obscure sightlines, along with loose patches that can develop quickly under heavy use. This trail is limited to ATVs and dirt bikes, and its moderate variability in surface and traffic makes it a practical environment for building confidence while remaining alert to changing trail conditions and rider behavior.
