September - October


Whale sharks are the largest fish in the sea. As filter feeders, they come to the nutrient rich waters of the Sea of Cortez to feast on the abundant plankton. During our tours, you can swim alongside these gentle giants or view them feeding from above. Whale sharks are currently on the endangered species list so this trip offers an optional training to contribute to science by learning about photo-IDs. Visual databases such as photo-identification have been used to individually catalog whale sharks and track their whereabouts for research and conservation purposes worldwide.

Route Bahia de los Angeles

We keep our group trips small to offer a more personalized experience with our marine biologist guides, so we can exercise best practices when encountering these marine mammals, out in the wild (i.e., per government regulations, only 4 individuals are allowed to swim with a whale shark at a time), and to let our guests truly disconnect and unwind.


With included pickups in San Diego and Tijuana, hotel accommodations, and photo package options, PROCETUS makes planning your next adventure easy! We utilize a private sprinter van to transport guests to and from our Baja locations with stops along the way. Our hotel partners also offer a tranquil place to rest in between wildlife sightings and are located in small coastal towns.

If you are looking to secure group rates or want a more customized trip, please inquire by email. We are happy to arrange family trips, honeymoons, etc.

*** Sightings are not guaranteed on our trips as these are wild animals and they can be highly migratory. However, we do guarantee that you will walk away with some newfound knowledge on marine species and memorable times out of the water! ***


Thank you! We will contact you shortly!


Safety for our guests and marine life is our number 1 priority.


We are currently taking COVID precautions by having clean and sanitized vehicles, hotels, and panga boats. Our guides are fully vaccinated and ready to take you on your next adventures!


We also carry a satellite phone for emergencies. Please note, for our whale shark trips, the nearest hospital is 2.5 hours away. Our team carries a first aid kid and there are local doctors available in town for minor injuries. However, in the event of major injury, it may be necessary to arrange for evacuation.
