Santa Ana River Trail is a paved two-way trail that runs 29 miles from Huntington Beach to just northwest of Corona. Its a steady low-graded uphill climb that follows alongside and over the river as it meanders through businesses and neighborhoods. There are future plans to extend the trail making it a total of 110 miles and stretching from Huntington Beach to Bear Lake and the San Bernardino Mountains. If you would like to make this route shorter, check TrailLink.com for additional trailhead locations and parking areas. Restrooms are available at the trailhead.
