Marlin Swim


Giant bait balls of sardines congregate off the shores of Magdalena bay each Autumn. Striped marlin, sea lions whales, sharks, and orcas feed off the baitball and you can be there in the water to see the whole show.

Marlin swim AKA ‘The Mexican sardine run’

Just a 5-hour drive from Cabo San Lucas, the ocean’s pelagic predator creates one of this planet’s most breathtaking shows. As the striped marlin are hunting, they dart towards the surface to push the sardines to shallow water, this gives us the opportunity to snorkel and free dive with these huge bait balls of sardines while the marlin zoom in and out of the school of fish flashing their beautiful colors.

What can we see??

Thousands of frigate birds that join the feast, hundreds of striped marlin, numerous sea lions, sailfish, orcas and the whales who pick off the scraps.

This is a once-in-a-lifetime trip and our highly experienced guide’s priority is safety and ensuring you have a wonderful experience.

The striped marlin is usually too fast and difficult to see under the water, you will have the chance to take outstanding photos in the circus of pelagic animals that join the sardine buffet.
