Marlin Swim, Mexican Sardine run


Every autumn giant bait balls congregate off the shores of Magdalena bay, imagine swimming alongside schools of striped marlin, bait balls of sardines, and sea lions at the same time with the chance of seeing whales and orcas…you can be there.

Just a 5 hours 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. Thousands of frigate birds join in the feast from the surface and numerous sea lions, sailfish, orcas and whales 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 average visibility is 90 ft/27 m so you can take this unique opportunity to get face to face with the striped marlin in their natural environment. This fish 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. This is a wildlife experience you can enjoy for the entire day, and remember for life.


October/November beginning from your hotel and the action happens off the wild coastline of the Baja California Peninsula in the Pacific Ocean.

Day 1:

You will be collected from your accommodation in Cabo San Lucas, San Jose or La Paz in an air-conditioned vehicle.  From here we will drive North for around 5-6 hours, we give you the opportunity to be flexible and see more of the wonderful Baja as you will have the opportunity to stop along the way to see the cactus-filled deserts of Baja, local famous restaurants or beaches.

On arrival to Magdelena bay, we will check into our hotel and enjoy a typical Mexican dinner in a quiet town away from city life and tourism.

Day 2:

7 am is wake up and breakfast before we head to the boat.  Our captain will take us to get to the mouth of the port where our talented and experienced guides and captains search for the bait ball in question. You will be advised when to enter the water and your guide will lead you to the area of the action so you can swim alongside the wonderful striped marlin and other pelagic guests that choose to join you.

When it gets closer to the end of the day and you are ready we will head back to the port, and make our way back in the air-conditioned transportation where you will be taken to the door of your hotel in La Paz, Cabo or San Jose.

Striped Marlin

Striped marlins are classed as near threatened according to the IUCN Red List so this excursion provides the opportunity to swim with striped marlin and enjoy their beauty in the water rather than a result of sport fishing or commercial fishing.


Our priority is your safety. You will receive a full safety briefing on the boat before you swim so you understand the behavior of the animals and how to experience the best encounter. Your group will be lead by a skilled and experienced guide with a strong aquatic ability to allow you to get the most from the experience. This trip is for beginners as well as professionals, you do not need experience however you do need to have good swimming ability and a good level of fitness.
