The Mexican Sardine Run – A Striped Marlin Expedition by La Paz Divers
Immerse yourself in the Mexican Sardine Run—an exhilerating natural phenomenon off the Baja California Peninsula. At La Paz Divers, we invite you to experience an unparalleled striped marlin expedition in the open ocean outside of Magdalena Bay, Mexico.
What You’ll Experience on the Mexican Sardine Run Tour
Between October and January, sardines in their millions congregate in the open ocean off the coast of Magdalena Bay. Schools of these plankton-eating fish shape themselves into swirling bait balls that attract the attention of high-profile marine predators. These include striped marlin, black marlin, dorado, dolphins, whales, sea lions, and marine birds. Such interactions regularly result in theatrical displays of raw nature.
We utilise panga boats with outboard motors that can quickly and efficiently get us to where the action is. Our local captains expertly scan the horizon for signs of pelicans and frigatebirds engaged in feeding activity on fish close to the surface, eventually leading us to bait balls under predation pressure.
