Santa Ana River Trail – aka SART – can be ridden as a loop or as a shuttle ride from South Fork Campground to Angelus Oaks. This trail is really fun and sometimes also very challenging. Watch out for sections with deep sand as they can be surprisingly tricky. Great views over Pinezanita – highly recommended!
