Mexican Sardine Run

During October and November, a magical event happens in the nutrient rich swirling blue waters off Magdalena Bay where striped marlin gather to hunt on the second largest sardine run in the world. This thrilling underwater action is spectacular. There is an excellent chance of also seeing california sea lions, dolphin, wahoo, pelicans, different species of gulls, boobie birds, frigate birds, shearwaters and even the awe inspiring albatross.

While it’s best to snorkel or free dive around the bait balls there will be plenty of scuba diving opportunities on your week long trip with massive schools of fish, turtles and the wreck of a WW1 submarine and the passenger steam ship SS Independence. But wait, there is more! Humpback whales are on the move at this time of year and if we are really lucky, we might even see orcas or blue whales!
