My Bucket List Adventure

When I told my family that I was going to La Paz, Mexico, to swim with sharks, they were very worried about me. It made me smile, since I hadn’t bothered to mention that I would be swimming with whale sharks, the gentle giants of the ocean.

These filter feeders are not dangerous to humans because they eat plankton and other tiny organisms by opening their wide mouth, allowing the sea water to rush in and filter through their gills.

There are no big shark teeth or any threat to humans.

But there is a magical experience, even when I did it on a day when the waters had been churned into murkiness by passing storms. Still, the wonder of being in the water with these fish that can grow to be 40 feet long is a bucket list adventure.

The Experience

The first step is to book a tour with a licensed tour company, like these listed on TripAdvisor. Read the details and reviews before you book. Expect to pay more than $100/person. If you’re traveling with kids, check the minimum age requirements so no one is disappointed when you’re out on the water.

During our March 2026 outing, we were outfitted with wetsuits, snorkels, face masks and fins. There were six in our group, so the guide divided us up. Only three of us were in the water at a time, staying well below the legal limit of five swimmers plus one guide swimming alongside a whale shark at any time.

We waited eagerly for the captain to get us to the whale sharks. As soon as he gave us the high sign, the first group swung their legs over the side of the boat and slid silently into the water.

After about 15 minutes, the first group returned to the boat and my group slid over the side into the chilly waters. The guide immediately grabbed me and pulled me closer to the whale shark. I dipped my mask into the murky water and gasped as the magical creature glided beneath me.

It was tough to keep the required six feet away from the fish as they moved through the water unpredictably. I found myself kicking fast to stay out of the way.

The first swim, I wore a life jacket. But I found it made it much harder to maneuver easily in the water. I’m a strong swimmer, so I felt comfortable without a life jacket. One of our group did not; she wore hers the entire time, a smart move for anyone who isn’t completely comfortable in the water.

SheBuysTravel Tip: It’s tempting to spend all of your time trying to shoot the best video or photo of these immense creatures. Don’t do it! After my first two (mostly failed) attempts, I left my phone on the boat and just relaxed into this special experience.As a result, my photos are not great, but my memories are extraordinary.

Lunch on Balandra Bay Beach

After two hours of swimming with the whale sharks, we were famished and ready for a little R&R. Lucky for us, one of the world’s most beautiful beaches, Balandra Bay Beach, was just a short boat ride away.

The beach was deserted when we arrived. We spread out our beach towels and waded into the shallow water while the guides set up our ceviche lunch.

Balandra is one of the best beaches in Mexico and the best-known stretch of shoreline in La Paz. If you don’t come by boat, it’s easy to get to the beach by car. It’s about a 15-minute drive from La Paz city.

Along the way to our nearly private beach, we saw dolphins and humpback whales and stopped to swim with some sea lions. It was, one my fellow travelers declared, “A 20 out of 10 day!”

I had my bucket list adventure in the Bay of La Paz, Mexico, between the Baja California Sur Peninsula and mainland Mexico. The legal season for swimming with whale sharks in La Paz is October through April.

But there are other spots around the world where you can swim with these giants of the sea:

Ningaloo Reef, Australia: A beautiful, highly regulated snorkeling experience, from March to July.
Yucatán Peninsula, Mexico: The waters off Isla Mujeres and Isla Holbox see huge aggregations of whale sharks from June to September.
South Ari Atoll, Maldives: Known for year-round sightings, particularly at the Maamigili Marine Area.
Donsol Bay, Philippines: Famous for large, seasonal aggregations from November to May.
Atlanta, Georgia, USA: Anyone age 12 and up can swim with these gentle giants at the Georgia Aquarium in Atlanta.
