Lake Perris State Recreation Area is a popular drivable destination for boating, shoreline walks and established camping areas reachable by paved roads. Mount San Jacinto State Park offers higher-elevation hiking and scenic drives that reward a bit of extra time on the road. The San Jacinto Wildlife Area provides short drives for wildlife viewing and roadside pull-outs that suit a campervan. For longer hauls, Interstate 10 is the main corridor: it’s a wide, traveler-friendly highway with abundant services and ample room for larger RVs.
