Cucamonga-Guasti Regional Park provides reservable RV sites with hookups and has food and fuel options a short drive from Bloomington. Auto Club Speedway offers designated event RV parking with on-site services and dump stations during races and concerts, convenient for short-term stays. For a change of pace, Heart Bar Campground in the nearby national forest gives a more rustic setting for those who want quieter nights and mountain access, though services are more limited. These choices let Bloomington-based travelers pick full-service parks or backcountry-style campgrounds depending on the trip plan.
