Expedition Overview

Join the non-stop, breathtaking action

Predators big and small are on the hunt during the annual Mexican sardine run where the underwater action is fast and furious. And the best encounters take place within ten meters (30 feet) of the surface, making this a perfect adventure for non-divers, free divers, and snorkelers to see:

  • Striped Marlins who are the star of the show
  • California Sea Lions join the chase and compete with the Marlin
  • Frigate Birds with sharp eyes track the sardines, making it easy for us to find the action
  • Bonitos, Bryde’s Whales, and Tiger Sharks show up, but with less frequency than the marlins of the sea lions
  • Every once in awhile, we get really lucky, and a pod of transient Orcas shows up

Liveaboard — Avoid Traffic, Spend More time In the Water

After years of getting up very early and sitting in traffic for hours on the way to and from the boat, I have now set up a new liveaboard option to eliminate that part of this adventure, opting instead for the comfort, luxury, and convenience of our floating hotel, the catamaran Mango Wind. At 45′ x 24′ wide, this vessel offers three large cabins, each with one queen-size bed, private head and shower, and individually controlled air conditioning.

Each morning, we will depart from our mooring, located in a safe, quiet bay at the entrance to Magdalena Bay and the Pacific Ocean, at least one hour away from the nearby town of San Carlos. This arrangement should save us the roughly two hours of daily travel that it normally takes to get back and forth from the marina to the hotel. We can also expect to be the first onsite each morning for the sardine and the marlin action, and we will have the option to stay at sea after everyone else leaves at 3 p.m., enjoying the beautiful warm light just before sunset from the deck of the boat.

More Details

Liveaboard Advantage

At 8:30am — a full hour ahead of everyone else — we will be crusing past the opening of Magdalena Bay, our captain will already be receiving bait ball positioning from fishing vessels returning from their night’s work — they are our the best source of information. Once we have a destination, the skipper revs the engine as we speed ahead over the calm blue waters as we head out for the day.


Finding the Sardines

Frigate bird formations over the water give us the exact location of the sardine bait balls. The closer the birds hover over the water and the tighter their formations are as they dive, the closer we are to the action. Once alongside a sardine ball, we reach for our fins, masks, snorkels, and cameras. Sitting on the edge of the boat, you are ready to jump into the fray — where there are sardines, there are likely Marlins too!


Jumping In

The sardine run is an exhilarating experience, and it is one that is not to be missed. Once in the water, hundreds of sardines will suddenly surround you, the sunbeams reflected off their silvery scales, they circle in a tight ball, but their defense makes them an easy target for the marlins, seals, and whales. Usually there are dozens of marlins will darting in and out of the ball, hunting their prey. Sometimes we even get to see them work together to corral the sardines and push them towards the surface, making them easier targets.




Up Close Experience

We will be far enough away to avoid interrupting the natural order of things, but still in the middle of the kleidescope — without notice, the marlins may start swimming in patterns that are unrecognizable to anyone but them.


Life Everywhere

The quickly sardine ball will change formation in a feudal attempt to fend off the predators. This means a constantly dynamic experience.  At one time the ball may be long, deep, and tightly wound, whereas at another point it may be loose and shallow. Throughout these changes, we will be surrounded by lively, beautiful images, as light constantly shifts its reflection off the millions of scales present in the sardine ball.


Marlins Feeding

A marlin will hit one fish at a time with its long bill in order to injure it and and move it away from the ball. As the other sardines run away, the marlin will eat the fish its prey. The sardine run is both a treasure to the eyes as well as a challenge to the body, as we will constantly try to keep up with the action around us as the marlins enjoy their full day of feasting.






Whales and Seals

Marlins are not the only animals drawn to the sardines. On this trip, we will also be treated to California seals who are competing with the marlins for food.


Suddenly, Orcas!

Orcas are also present in the area, and we have even had an experience where we swam with a transient pod of 6 orcas for two and a half hours! He witnessed the adults sharing food with their young, and it seemed as if the orcas were inviting him to observe their lives. Although less likely than seeing seals and orcas, Bryde’s whales, with lengths up to 30 or 40 feet, may also arrive from time to time to get their share. All of a sudden, a bright day just underneath the ocean surface can grow darker as the shadows of the whales show up quietly and unannounced. When whales appear, the seals and marlins make way for these larger creatures to feed. We will work to find the best angles and keep up with the action, whether the sardine ball we encounter is static or moving.
