Snorkeling with Whale Sharks - The right way
Snorkeling with Whale Sharks
Eco - Tourism
Citizen Scientist Expedition
If you’ve ever dreamed of swimming alongside a whale shark, you’re not alone. These gentle giants are one of the ocean’s most incredible creatures. This magical experience can be, not all whale shark tours are created equal. Some can harm the animals and disrupt their natural behavior.
A better option is joining a citizen scientist expedition. These trips are designed to let you enjoy the experience while helping researchers learn more about whale sharks and how to protect them. You won’t just be watching, you’ll be collecting useful information, like photos of their spot patterns or notes on their behavior, that scientists can use for conservation work.
Why Choose an Expedition Instead of a Regular Tour
Standard tourist snorkeling trips often mean large groups, crowded waters, and very little learning. This can stress the animals and turn the experience into little more than a quick photo opportunity. What a nightmare for the Whale Sharks to be crowded by 100 to 200+ humans blocking them from the surface.
Citizen scientist expeditions keep groups small. You spend more time with the animals and learn directly from marine biologists or trained guides. The focus is on observation and respect, so the whale sharks are not chased, touched, or surrounded.
You also gain a deeper understanding of the species, the threats they face, and how your actions can help them survive. It’s a more meaningful encounter, and the data you help collect goes toward real research projects.
What You’ll Do on a Citizen Scientist Trip
Most programs begin with a briefing about whale shark biology, migration, and identification. Out on the water, you’ll take photographs that capture their unique spot patterns. These patterns are like fingerprints, allowing scientists to track individuals over time.
Some trips also include tagging projects or recording environmental details like water temperature and plankton density. Your contributions go into global databases that help track migration routes, estimate population sizes, and identify critical feeding areas.
Best Places to Join a Whale Shark Expedition
Isla Mujeres, Mexico – May to September is prime season, with calm waters and plenty of opportunities to also see manta rays and turtles.
Galápagos Islands – August and September are best, especially near Wolf and Darwin Islands. Many sightings are of large females, possibly linked to reproduction.
Maldives – Sightings year-round, but January to May offers the best visibility.
Mozambique – Excellent diving and research programs focusing on whale sharks and mantas.
Philippines – A well-known spot for ethical encounters, usually from November to June.
The Pros and Cons
Pros
Better for the animals—no baiting or crowding.
Smaller groups for a calmer experience.
Direct learning from marine experts.
The data you collect supports conservation work.
Cons
Often more expensive than tourist trips.
May require multi-day commitments.
Schedules follow research needs, not tourist convenience.
Can be physically demanding.
Understanding Whale Sharks
Whale sharks are the largest fish in the world, reaching lengths of up to 40 feet. Despite their size, they feed on tiny plankton and small fish. They live long lives, possibly 80 to 130 years and grow slowly.
Males and females can be told apart by the presence of claspers (reproductive organs) near the tail on males. Their spot patterns are unique to each individual and help researchers identify and track them. The size and markings can sometimes offer clues to their age, but much about their life cycle is still a mystery.
When and Where They Migrate
Whale sharks follow food sources, especially plankton blooms.
Yucatán Peninsula, Mexico – May to September.
Galápagos Islands – August to September.
Maldives – January to May.
Tanzania – October to February.
How You Can Help Protect Whale Sharks
Choose ethical expeditions over crowded tourist tours.
Share photos with global ID databases like Sharkbook.
Support marine protected areas that safeguard feeding and breeding grounds.
Reduce plastic use and marine litter, which harm their food sources.
Whale sharks are slow to mature and reproduce, which makes them vulnerable to overfishing and habitat loss. Every responsible encounter helps raise awareness and contributes to the knowledge scientists need to protect them.
Swimming with a whale shark in an ethical way is not just about the thrill of the moment. It’s about leaving the ocean better than you found it and knowing that your time in the water helped ensure these giants will still be here in the future.
Chose your adventures wisely!

Planning . Planning is an essential for any trip, so keep track of all of your information that you might need along the way. Making a list of important phone numbers, addresses, email addresses, contact information readily available while you travel. Having the information saved offline, in the cloud or your email is a great idea.
Isla Contoy, Mexico
Weather. What time of year has the best weather to enjoy our visit? Most of the year is a great time to visit. The exception is when there is a hurricane. Currently, hurricane season is approximately June through November, but they are unpredictable & sporadic, so there is no fool-proof way to plan around them. Since it varies so much, its highly recommend getting travelers insurance for any time of year that you visit. The most popular time to visit is the winter months of November to April. The summer into fall months of May to October are still a beautiful time to visit, but you may have a rain shower pop up.
There’s a lot of weather websites that are popular, but the National Weather Service is a great resource for up-to-date information. National Hurricane Center – NOAA Weather: weather.gov.
Sunset Cruise, Mexico
Booking. For this trip, I booked with Cancun Sailing. If you’re looking for discounts, check for specials, especially around the holidays. The calendar on the website shows the cost for the day. If you’re a local resident, check for discounts, but make sure that you bring your ID with you at pick up. Cancun Sailing has a great cancelation policy in case of bad weather, etc. Also, remember Isla Contoy limits how many people visit per day, so make sure to book your reservation before you arrive – don’t wait too long in the high season.
Transportation, Pick-up & Check In
Transportation. The day started out by meeting at one of many pickup points along Cancan Sailing’s route. I was picked up in a luxury van that held about 20 passengers. Having the convenience, along with the cost of the transportation included, made the morning stress-free. The driver was very pleasant and he confirmed my reservation while making sure that everyone was on the list. After picking up everyone, we were driven directly to the dock in Cancun, where we were promptly checked-in. The pick-up locations and addresses are located on their website. There are a lot of convenient locations for pick-ups, including most major hotels & resorts. The cost was included in the price at the time that I went
Cancún, Mexico
Check-in. When I arrived at the dock, I was dropped off right in front of the check-in area. There seemed to be a lot of people getting ready to board different boats, but they were very organized. The check-in went smoothly and it was also nice to have the ride to and from home included and organized with the excursion. One less thing to try and coordinate.
Isla Mujeres, Mexico
What to expect – First Island: Isla Mujeres, Mexico
The Boat Ride. Setting sail on the boat ride to Isle Mujeres was very pleasant with a soft breeze, while enjoying the changing of several shades of the blue in ocean. The sailboat was clean and could accommodate approximately 50 people. It didn’t feel over-crowded and had an excellent crew, but can experience getting wet. Keep your items dry in a Wet Bag, like this one - Wet Bag.

By the time we were getting close to the island, everyone was suited up in life vests and snorkel gear. It was time to snorkel in the beautiful water, which is part of the Mesoamerican Barrier Reef, the second-largest reef system in the world. This underwater paradise is filled with colorful corals, tropical fish, and other fascinating marine life. The time went by fast, but we enjoyed the approximately 45 minutes of water time.
Snorkel Site Isla Mujeres, Mexico
Once we all were back on board from snorkeling, we took a short sail and docked for a quick land tour of Isla Mujeres, to get a peek of the island and to experience both sea & land. After exited the boat and leaving the docking area, I turned left toward the white sandy beaches. The beaches and turquoise water is a beautiful sight to see, while visiting the Isla Mujeres.
To ensure the best views under water, bring your own snorkeling mask and treat it with Stream2Sea Prep Kit and reef safe Mask Defog.
Isla Mujeres Dock, Mexico
Since the time allotted to visit Isla Mujeres was short, I utilized my time on the beach and then strolled back to the dock through the shopping areas to get a feel of what the island has to offer. This time was considered “free time” and you were able to do what you wanted, without a guide. Next time I visit, it will be to scuba dive, snorkel & relax on the beach – probably away from the many shops but not too far away from the many restaurants. It was a beautiful island and I see why this it is so popular.
Isla Mujeres Beach, Mexico
On Isla Mujeres, maps are located around the dock area so you will be able to find your way around. Don’t miss the leaving at the time they give you and note that your docking number is written on the bracelet that you receive when you docked on the island. It may be different than from where you arrived, but should be close by.
Isla Mujeres Beaches, Mexico
Back on the boat, everyone enjoyed music and conversation with their fellow sailing mates while we sailed to our next destination. The boat crew has a full bar, so you can ask for water, juices, beer, wine & mixed drinks, along with snacks. Drinks & snacks are included!
Good Bye Isla Mujeres ~ Hello Isla Contoy

Tour: I highly recommend taking the educational tour that they offer to learn about the island. The main guided tour was after lunch, which is given in Spanish for the visitors from Spain. The guides spoke several languages and offered the small group of us an English-speaking tour right when we arrived, which I enjoyed.
Isla Contoy Lagoon & Birds
The tour was an amazing, well worth the 20-to-30-minutes it took to complete. Just know that when they ask if you want to see the lagoon that is full of mosquitos, you can ask to skip that part of the tour if you wish. The guided tours and all activities are supervised by certified ggouides to ensure adherence to conservation rules, but you had a free range of a lot of space to explore while you’re there. Shoes to walk in the sand on your short hike up the hill would be something to keep in mind while packing.

A final note about Isla Contoy and many beaches in the surrounding area. There are a lot of beaches in Mexico and throughout, that are Blue Flagged Beaches. These beaches have rules in place to help preserve the natural habitats of the wildlife in the areas. Read more about blue flagged beaches, but one rule is zero sunscreen is allowed once you disembark from the boat, so plan on accordingly.
The best sunscreen for in the ocean is RPF - Reef Protection Factor - Coral Care sunscreen by Stream2Sea before leaving the boat. Know that once you dock on Isla Contoy, you have to leave any chemicals and plastics on the boat, including sunscreen & bug sprays.

If you’re a fan of sunscreen in the mornings before you start your day of adventures, read more on the truth about Sunscreens on My Spinning Mind Travels, Stream2Sea, Reef Relief & other trusted websites.
While researching for the best & safest sunscreen, there’s a very small number of companies that produce a good, safe product but I’m hopeful that will change for the better. If all sunscreen was truly reef safe, we won’t have these restrictions.
Until those changes are made, check out the what Ingredients to Avoid List when buying sunscreen and help with demanding safe sunscreens.
Support the sunscreen companies that are making a difference in helping us by producing safe products for us and the environment. I’ve have found Stream2Sea has been a wealth of information and I’ve discovered my favorite sunscreen that I use for daily sunscreen protection, which is also great for day adventures.
When you apply Stream2Sea, Everyday Wet Boost Sunscreen in the morning, it last most of the day, even when you’re in humid weather or enjoying water sports for protection of UV rays.
Travel friendly - mini tin Sport Zinc Balm sunscreen is the most convenient to have in your bag when needed throughout the day.
