Topocalma is an exposed major headland that draws in swell onto a scruffy array of fringing rocks. There will be more lefts off the north side of the Pan de Azúcar rocks leading into the beachbreaks, which can get scoured by the river when it opens. Nothing epic but an escape from the Puertocillo crowds and flatness.
Watch out for currents and rocks popping up everywhere. The beachbreak between the point and the rocks is often OK for beginners on the inside.
