Bull Shark Diving in Playa del Carmen: Observe.
Don't interfere.
The experience
A different kind of encounter.
Every winter, bull sharks are seasonally present off Playa del Carmen. We dive to a sandy-bottom observation area at approximately 22–25 m (72–82 ft), with a maximum bottom time of 30 minutes.
The experience is about observing, not interacting. We're there to see the sharks, not change their behavior.
We operate from November 1 through March 31. The number of sharks, their distance, their behavior and visibility are natural and can vary — sightings are never guaranteed. Outside the season, this page stays here so you can plan ahead.
Two dives, one purpose
The encounter starts before the sharks.
The day includes two dives. The first is preparation and a safety measure: safety comes before proceeding with any particular dive.
01
Reef / check dive
Approx. 10–14 m / 33–46 ft
Time to settle into the water. Your guide sees how you're doing underwater before the deeper encounter.
- Equipment check
- Buoyancy and weighting
- Trim and body control
- Breathing and comfort
- Communication
- Group coordination
02
Bull shark encounter
Approx. 22–25 m / 72–82 ft
We descend along the line to a sandy-bottom observation area. Your guide sets the position, and the group stays calm and controlled while observing.
- Maximum bottom time: 30 minutes
- Sandy-bottom observation area
- Guided positioning
Passive observation
Observe.
Don't interfere.
No feeding · No baiting · No touching
The goal is to observe natural behavior rather than create an interaction. We don't use food or bait to bring sharks closer, we don't touch or handle the animals, and divers don't actively approach them. CDT chooses passive observation.

Divers per guide.
Up to four divers per guide. Traveling with a larger group? You're welcome to book together — we'll add another guide and divide the group thoughtfully, keeping each guide with no more than four divers.
Your group stays together as an experience, while each guide works with a small number of divers in the water — supporting communication, preparation and controlled observation.

Why Playa del Carmen
Why they're here matters.
Playa del Carmen receives a seasonal aggregation of bull sharks during the winter months.
A 2023 peer-reviewed study used underwater ultrasound on free-swimming bull sharks here and confirmed embryos in three females, suggesting the area may be important habitat during gestation. Much about the aggregation is still being studied — another reason to observe quietly and leave their behavior undisturbed.
Bull shark FAQ
Questions before you dive
When is bull shark season in Playa del Carmen?
CDT operates this seasonal experience from November 1 through March 31. Shark presence and environmental conditions remain natural and can vary.
What certification do I need?
Advanced Open Water or equivalent is the minimum certification. Recent deep-diving experience, solid buoyancy and good underwater control are also important.
How deep is the shark dive?
The encounter is normally conducted at approximately 22–25 m (72–82 ft).
Do you feed the sharks?
No. CDT does not use feeding or baiting for this experience. The encounter is based on passive observation.
How many dives are included?
Two. The first is a reef/check dive at approximately 10–14 m. The second is the bull shark encounter at approximately 22–25 m.
Why do we make the reef dive first?
It allows the diver to settle into the water and gives the guide an opportunity to observe buoyancy, weighting, control, communication and comfort before the deeper encounter.
How many divers are in each group?
Up to four divers per guide. Traveling with a larger group? You're welcome to book together — we'll add another guide and divide the group thoughtfully, keeping each guide with no more than four divers.
Are bull sharks guaranteed?
No. Bull sharks are wild animals. Their presence, number, behavior and proximity cannot be guaranteed. We never use feeding, baiting, touching or handling to force a closer encounter. Ocean conditions or official closures may also require changes, as explained in our Terms & Conditions.
Is Nitrox available?
Yes. Nitrox 32 is available at no additional charge for appropriately certified enriched-air divers.
