Nothing could quite prepare us for the moment when we first saw a massive whale shark gliding slowly by, just feet away. It was one of those OMG moments, an almost other-worldly experience.
How wondrous that we could swim with whale sharks in La Paz – that these creatures allowed us to snorkel alongside them in the wild!
Interesting facts about whale sharks
Whale sharks are actually not whales (or sharks). They’re fish – the largest fish in the world. They’re known to grow up to 40 feet long and weigh up to 47,000 pounds!
But even though whale sharks are humungous, they are really just “gentle giants.”
Grey with white spots, they eat only tiny plankton and krill. And they’re not at all dangerous to divers, snorkelers and swimmers.
The only concern we had when swimming with the whale sharks was to stay away from their cavernous mouths. To feed, they open their mouths very wide to suck in gallons of sea water from which to filter out algae, plankton and krill.
And our concern wasn’t so much for us – it was for the whale sharks. We didn’t want to accidentally poke them in their open mouths with a flippered foot.
Day tour to swim with whale sharks in La Paz
We took a day tour with Cabo Expeditions, which picked us up from our resort in Cabo San Lucas and drove us by van to La Paz (about a two-hour drive).
In La Paz, we geared up in wet suits, then climbed aboard our boat for the ride out into the bay.
We were accompanied by our Cabo Expeditions guide and a federally licensed local guide with good knowledge of marine biology (along with a boat captain, of course).
Arial spotter planes looked for the whale sharks from above, communicating their location to our boat captain.
Other pangas and boats also descended on the spot where four or five whale sharks were feeding.
Swimming with whale sharks (not easy!)
When a whale shark was spotted swimming close by our boat, our guide shouted at us to jump in the water and swim up to it.
We felt like paratroopers, quickly jumping in one after the other like dominoes.
Then we’d swim alongside the whale shark while peering down at it through our snorkel mask. When it swam away from us and we couldn’t follow it any more, we’d swim back to the boat, climb aboard and wait for the next whale shark to watch.
Jump, swim, observe, repeat.
And imprint this awesome once-in-a-lifetime experience in memory.
Brrr… it’s so cold
But while tremendously exciting to be watching whale sharks up close, it was hard to ignore the cold seeping into our bones and stiffening our fingers. (We went in early January.)
In winter, which is the La Paz whale shark season, the water temperature drops to the low 60s.
So we felt both regret and relief when it was time to say goodbye to the whale sharks and return to La Paz.
After, we tucked into hot soup and tortillas at a local Mexican restaurant, before being driven back to Cabo.
One of the best Cabo excursions!
We’ve enjoyed many Cabo excursions during the countless times we’ve visited Los Cabos.
Without a doubt, we can say that taking a La Paz whale sharks tour is one of the best things to do in Cabo San Lucas!
Where else to swim with whale sharks in Mexico?
La Paz isn’t the only spot in Mexico where you can go swimming with whale sharks.
The other place to swim with whale sharks in Mexico is around Isla Holbox.
It’s a small unspoiled island north of Cancun.
The Holbox and Cancun whale shark season is June to September – and the waters are quite warm and comfortable then.
Many tourists book their tours from Cancun, where they stay. Be aware, however, that this involves about a 2-hour boat ride (often choppy) to get to where the whale sharks feed, and sea sickness can be an issue on the boat ride.
The other option for swimming with whale sharks in Cancun is to catch the bus from Cancun (3 1/2-hour ride) and ferry (1/2-hour ride) to Isla Holbox, and take your whale shark tour from the island.
The island boasts beautiful white sand beaches, and there are places to stay in Isla Holbox.
You still have a longish boat ride to reach the whale sharks’ feeding site, but some say the waters are calmer and sea sickness is less of a problem on Isla Holbox tours.

We paid Cabo Expeditions a discounted media rate to experience this whale shark swim. But as professional travel writers, we always report on our experiences as we see them (and point out issues you should know about).
