The villages of Rancho Del Oro make-up the heart of Oceanside. This has been a part of an aggressive development plan for Oceanside that comprises beautiful new homes, a corporate park as well plans for an impressive community park, El Corazon, that will offer bike trails, outdoor amphitheater, soccer fields, baseball fields and more. Notable companies within the business park are Genentech, Ashworth, and Robert Mann Packaging. Beautiful rolling hills integrate new Oceanside with historic Oceanside, representing our rich culture and heritage. These icons include Heritage Park and the largest of the California Missions, Mission San Luis Rey. Visitors and locals alike enjoy this architectural beauty in its peaceful surroundings.
