Frequently asked questions

Send us a dive request or message us so we can plan the day with you. A reservation is confirmed once the deposit has been received.

20% per person, per activity. If you book more than one activity, the deposit applies to each one. The balance is normally paid on the day, before the activity begins, unless other arrangements were agreed in writing.

Credit and debit cards, PayPal, Mercado Pago, bank transfer and cash. Some payment methods may involve processing fees; any applicable fee is shared with you before payment.

The amounts paid for the canceled activity are refundable, less any non-recoverable bank or payment-processing fees associated with the original transaction or refund.

We retain the 20% deposit. If you already paid the full activity, we refund the remaining amount, less any applicable non-recoverable bank or payment-processing costs.

Because guides, logistics and operational resources are reserved specifically for your activity, no-shows and arrivals that make the scheduled activity impossible are non-refundable. Minor delays are not automatically treated as a no-show.

No. Rain and ordinary weather do not normally prevent cenote diving. Cancellation happens only in exceptional circumstances that create a genuine safety or access risk, such as hurricanes, major storms, unsafe transportation or official closures.

Cozumel and bull shark dives depend on sea conditions and official navigation closures. They may need to be modified, rescheduled or canceled when marine operations are unsafe. If we cancel and can't reschedule, you may receive a refund for the affected CDT activity.

The guide has final authority regarding dive safety, and may adjust the site, route, depth or plan, or decline a dive, when reasonably necessary to protect you and the team.

It isn't mandatory, but we strongly recommend appropriate diving accident insurance.

A liability release, a medical questionnaire or declaration and any other required participation documents, before diving. If the questionnaire indicates it, you may need medical clearance.

15, with appropriate authorization and accompaniment for minors. Activity-specific requirements still apply.

Yes. You dive with your guide and the divers you booked with. We don't add other divers to your day.

Two dives are included during the day. Depending on the cenotes chosen, both dives may take place within the same system or at two different cenotes. A third dive can also be added when the day's plan and logistics allow, for an additional USD 100.

You tell us your certification, recent diving and what you'd like to see. We propose the combination that fits, and we adjust it if conditions on the day suggest something different. If you'd rather we decide, we'll build the day for you.

It depends on the cenote. Level 01 and 02 cenotes (CREER classification) ask for Open Water or equivalent; Level 03, 04 and EX cenotes ask for Advanced Open Water or equivalent. CDT also asks that you have dived in the last six months; if not, we may recommend a refresher dive at Casa Cenote first. Dreamgate, Taak Bi Ha and Taak Bi Lum additionally require a prior dive with CDT. Buoyancy, comfort and the day's conditions also count.

No. CDT uses the CREER levels as a reference for the relative difficulty and characteristics of each cenote, not as a mandatory progression. For most cenotes, what matters is having the appropriate certification and having dived within the previous six months. Dreamgate, Taak Bi Ha and Taak Bi Lum additionally require a prior dive with CDT so the guide can understand your comfort, buoyancy and control before the dive.

Yes, at no extra cost if you are Nitrox certified.

Complete diving equipment and tanks are included.

Professional underwater photography is not included in the rate and can be arranged on request. Ask us when you write and we'll tell you what's possible for your dates.

Private transportation is included from Playa del Carmen and the surrounding area we normally cover. Pickups from farther locations, including Tulum and Cancún, can also be arranged for an additional charge. The exact transportation cost depends on your location and the dive plan for the day, so we confirm it before booking.

Open Water Diver is the minimum certification. Advanced Open Water is recommended for greater flexibility and access to deeper profiles and more advanced sites when conditions allow.

No. Full scuba equipment, including a wetsuit, is available as part of the experience. You're welcome to use your own equipment if you prefer.

This is private diving. Your guide is dedicated to your reservation group, with a maximum of six divers per guide. We do not combine your guided group with unrelated divers.

Yes. Diving in Cozumel is primarily drift diving. Dives are guided and planned according to conditions and the group's experience.

No. We do not offer Discover Scuba Diving (DSD) in Cozumel. This experience is for certified divers. If you're not certified yet, we can point you toward a more appropriate way to begin diving.

Contact us first so we can plan your dives. A 20% deposit per person, per activity secures the reservation, and the remaining balance is paid on the day, before the experience begins. Some payment methods may carry processing fees, which we share before you pay. Cancellation and weather conditions are in our Terms & Conditions.

CDT operates this seasonal experience from November 1 through March 31. Shark presence and environmental conditions remain natural and can vary.

Advanced Open Water or equivalent is the minimum certification. Recent deep-diving experience, solid buoyancy and good underwater control are also important.

The encounter is normally conducted at approximately 22–25 m (72–82 ft).

No. CDT does not use feeding or baiting for this experience. The encounter is based on passive observation.

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.

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.

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.

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.

Yes. Nitrox 32 is available at no additional charge for appropriately certified enriched-air divers.
