Swim with whale sharks in La Paz, Mexico: Wondrous!

Please only travel when and where it’s safe, and follow all local guidelines. Also double-check what's open before your trip.

Nothing could quite prepare us for the moment when we first saw a whale shark the size of a bus glide 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!

Snorkeling With Whale Sharks in La Paz

Whale sharks in La Paz

Whale sharks are unfortunately endangered.

However, there are still a handful of places in the world where you can swim with whale sharks.

The Bay of La Paz in Mexico’s Sea of Cortez is one such place.

Swimming with whale sharks is one of the must-do day trips from Cabo San Lucas.

Don’t miss it when on holiday in Los Cabos (or La Paz)!

We’ve experienced lots of incredible things to do in Mexico during our many visits to the country – this experience is one of the best.

Swimming with whale sharks in La Paz

We recently went swimming with whale sharks in La Paz (on the Baja Peninsula) a second time.

The experience was just as amazing as the first – only different.

The first time we booked our whale shark day trip with Cabo Expeditions.

The second time, we arranged our La Paz whale shark tour with Baja Charters, which uses a large catamaran as a support boat in the Bay of La Paz.

Swimming with the Baja whale sharks is one of the best day trips from Cabo San Lucas!

We’ll tell you all about these and other whale shark tours in La Paz in a jiff.

First, though, let’s get to know whale sharks a little better…

Interesting facts about whale sharks

Whale sharks are actually not whales (or sharks). They’re fish – the largest fish in the world.

They grow up to 60 feet long, weigh up to 47,000 pounds and live to a nice old age of 130 years.

But even though whale sharks are humongous, they are really just “gentle giants.”

Grey with white spots, they eat only tiny plankton and krill.

Their livers are huge – about 70% of a whale shark’s body is liver.

Swimming with whale sharks in La Paz, Mexico -- awesome!

And here’s a cool fact that Mariana, the marine biologist on our Baja Charters tour, told us.

When born, whale sharks are barely two feet long. To protect themselves from predators, they swim down some 3,000 feet underwater. It takes four months to grow to about six feet long, and then they swim back up to the surface.

Many things about whale sharks are not known, however.

How often they breed, the mating season, the length of gestation, when they have their babies – all of this is a mystery.

Is it safe to swim with whale sharks?

With whale sharks being so massive, you might naturally ask: Is it dangerous to swim with them?

Do whale sharks eat people?

Short answer, no. Whale sharks pose no threat 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 for us – a whale shark won’t swallow you. Even though their mouths can stretch to four feet wide, their sieve-like “gill rakers” are designed just to feed on tiny things.

No, our concern was for the whale sharks. We didn’t want to accidentally poke them in their open mouths with a flippered foot.

La Paz whale sharks

There are some 95 whale sharks in La Paz, mostly juveniles about 15 to 30 feet long.

The whale shark feeding zone in the Bay of La Paz (called “El Mogote”) became an underwater national park in March, 2019.

Swimming with the La Paz whale sharks is highly regulated by SEMARNAT (the Secretariat of Environment and Natural Resources).

Only 14 small pangas or boats are allowed in the protected area at a time. Each boat gets three hours in the water, and each boat can only have five people in the water at a time.

You can swim for three minutes alongside a whale shark then you must get out of the water.

Don’t worry though – that’s a long enough time! You have to work very hard to keep up with them. After a few minutes of full-on swimming, you’ll be quite breathless! 

The experience: Baja whale sharks with Cabo Expeditions

Our first tour with Cabo Expeditions included picking us up from our resort in Cabo San Lucas and driving 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.

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.

Afterwards, we were taken to a local Mexican restaurant in La Paz for a lunch of hot soup and tortillas, then driven back to Cabo.

Luxury catamaran tour with Baja Charters

The experience was so epic that we just had to make it a twice-in-a-lifetime experience…

Baja Charters operates a little differently.

Their day tours also include transfers to and from Cabo San Lucas, but they use the 60-foot catamaran “Island Cat” as a support boat.

Upon boarding the catamaran around 9:00 am, we were treated to coffee, cake and fruit and relaxed on the boat as it motored out into the bay.

It was unusually cool and overcast, so while we could have lounged about outside on cushions or the netting at the bow, everyone huddled instead inside the cat’s lounge.

The captain even put the heater on!

It was just as well we had a warm place to hang out, as we had to wait an hour until a couple of other pangas left the whale shark protected area.

Once cleared to go, we suited up in shorty wetsuits and boarded our panga (there were two pangas, ours had five guests).

We did four jumps into the water – one particularly surreal moment was looking right into the eye of one whale shark as it glided by just inches away.

And we saw at least ten whale sharks!

What struck us this time is that we got incredible views of the whale sharks right from the boat.

We could actually get a better overall view of them peering down at them from the boat, as they’d swim right up to the boat.

Our panga captain explained that whale sharks have poor eye sight, and he constantly had to manoever the panga to get it out of the path of the whale sharks.

Once in the water, it was difficult to see them until they were quite close because the water isn’t crystal clear.

All that plankton and food, which attracts the whale sharks, makes the water cloudy.

But it was thrilling to see first the mouth, then the gills and finally the tail as they passed by.

Before we knew it, three hours had zipped by and it was time to return to the “Island Cat.”

Shivering from the cold water, we made a beeline for the shower.

The “Island Cat” boasts two heads, each with a hot shower, and towels are supplied. Standing in a warm shower never felt so good!

By the time everyone had showered, a hot lunch of seared tuna and fresh-made tortillas with chicken and beef was waiting.

And the complimentary bar was open.

We hungrily filled our tummies, with visions of whale sharks filling our thoughts, as we sailed back to the La Paz marina.

Brrr… it’s so cold

While tremendously exciting to be watching whale sharks up close, it was hard on both occasions 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 Cabo.

When you plan your Los Cabos trip, you might actually want to stay in La Paz for a couple of days.

(There are more fun things to do in La Paz – like snorkeling with sea lions.)

Whale shark season, La Paz

The best time to see whale sharks in La Paz is from October to February.

The best time to go to Cabo (and La Paz) for warm water is October and November. The water will be almost bathtub warm then – but it’s chilly in January and February.

La Paz whale shark tours

Because swimming with whale sharks in La Paz is now highly regulated (boats, captains and guides must all be licensed), all tour operators are ecologically responsible.

From what we observed, boats maintained safe distances from the whale sharks to avoid hurting them, and there were only a few people in the water at a time from any one boat.

Expect to pay about $250+ USD p.p. for a day tour departing from Cabo San Lucas (up to $400 for a luxury tour). Tours from La Paz will be less.

Here are some of the best La Paz whale shark tour companies:

Cabo Expeditions:

We found Cabo Expeditions to be very conscientious and recommend them highly. Their 8-hour tours leave from Cabo (wet suits and snorkel gear provided). 

 Cabo Expeditions: Website

Baja Charters:

We also really enjoyed our small group tour with Baja Charters – and can highly recommend them too.

Their trips are more expensive than those offered by Cabo Expeditions. But you get the use of the “Island Cat” (and its hot showers!) plus a freshly prepared hot lunch on the boat.

Tours also include all snorkel gear (choice of full-face or standard snorkel masks), wet suits, towels and reef-friendly sunscreen.

Baja Charters: Website

Fun Baja:

We’ve heard from friends that Fun Baja (based in La Paz) also does a good job.

Fun Baja: Website

Cabo Adventures:

Cabo Adventures is another reputable company offering whale shark encounter experiences. We’ve booked other activities in Los Cabos with them and can recommend them. 

Cabo Adventures: Check out their whale shark tours here.


Manta Scuba Divers offers a day tour which combines two activities: swimming with whale sharks in Cabo at La Paz and scuba diving with curious sea lions at Los Islotes.

(We’ve gone scuba diving in Cabo San Lucas with Manta – they’re very good.)

You won't regret booking a tour to snorkel with the La Paz whale sharks!

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 Los Cabos!

Practical information for snorkeling with whale sharks


Don’t touch a whale shark (even though it’s quite easy to do). Touching them can transfer harmful bacteria from you to them, and make their skin vulnerable to infection.


If snorkeling with whale sharks in La Paz, know that you might find the water cold even with a wetsuit (depending on the month you go).

Try to rent a thicker wetsuit or wear an additional wetsuit vest for extra warmth.

If you wear sunscreen, use a reef-friendly biodegradable product so the chemicals don’t harm the marine life.

Be aware:

La Paz is one of the few places in the world where you can swim with whale sharks.

You’re in the water with very large animals.

If you don’t think you’ll be comfortable with this, swimming with whale sharks may not be the tour for you.

Where else can you 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, a small unspoiled island north of Cancun.

From the island, you can take an Isla Holbox tour to swim and snorkel with the whale sharks that gather to feed in the plankton-rich waters there. (Getting up close-and-personal with whale sharks is one of the best things to do in the Riviera Maya.)

The water is comfortably warm during the whale shark season there (which is in summer).

Thanks for this post! Did both of your tours leave from La Paz or just the one? We are staying in Cabo but were told to go to La Paz for whale sharks. Just wondering if there is any way to avoid the long drive to La Paz. Thank you so much!

Hi Lauren, We were staying in Cabo, so we did both of our tours from Cabo. Round-trip transportation in a comfortable van was provided as part of the tour price - so you don't have to drive yourself :-). It means an early start to the day, but swimming with the whale sharks is sooo worth it.

Hi What can we see other than the whale shark in November around La Paz? Thanks

The snorkeling will be great in the Sea of Cortez! The water will be nice and warm -- lucky you :-). You might also want to go snorkeling with sea lions at Espiritu Santos Island, which is part of the UNESCO-protected Islas de Golfo de California Biosphere Reserve. The island is home to a colony of some 300 sea lions. Some tour operators add kayaking to the tour as well as snorkeling. Have fun your trip!

I'm heading to Cabo the first week of January to do this! My first time traveling out of the country BY MYSELF for 5 days of scuba diving and whale shark-ing and swimming with mako and silkie sharks. I CANNOT wait!

Janice and George

Tuesday 10th of September 2019

Exciting! Whale sharks are just one of the many incredibly diverse underwater creatures (e.g., jumping Mobula rays, sea lions, dolphins, whales) you can see in the Sea of Cortez. As for sharks, you've already named makos and silkies. There are also blue sharks, tiger sharks and hammerheads. Have an awesome dive holiday!
