About us
At Kay Diving we are passionate about the Mayan underworld. Our guides will not only take you on a personalised experience, they will teach you about the magical history of this place. We also take pride in our responsibility towards the environment, making conscious decisions about the way we protect this beautiful planet.
The Riviera Maya has some of the most beautiful diving sites in the world, and some very good dive centres. What we take special pride in is making the tour yours — so that you feel at home, and the day is built around you rather than around a schedule.
Before you arrive
We send you a few questions before the dive. What you have done before, what you want out of the day, what makes you uneasy. It is the difference between a dive that suits you and a dive that merely happens.
What we run
Every price below already includes your equipment, the cenote entrance fees, transport between the dive sites and snacks in between dives. Hotel pickup is the one thing quoted separately — see Getting there.
No PADI? No problem.
Your first glimpse of the underwater world. Learn the basics of scuba, then go and explore an open-air cenote with crystal clear water, no deeper than seven metres. No certification, no previous experience — just a guide, shallow water and a very good morning. The second dive only runs if the sea is right that day.
Two worlds unveiled at once.
One day, both halves of what makes this coast worth diving: the reef off Tankah, then the fresh water of Casa Cenote. Salt and sweet, turtles and stalactites, in a single morning.
Explore the Mayan underworld.
Into some of the most beautiful flooded caverns in the world. You choose the cenotes with us, and which ones are open to you depends on your certification — Angelita and El Pit are the two that pass thirty metres.
The deep two
Join the fun, become a certified diver.
The full PADI Open Water licence over five dives, between Casa Cenote and the Tankah reef. No previous experience needed. You leave with a certification that works anywhere in the world.
Climb the experience ladder.
The next step: five specialty dives taking you to thirty metres, in Cenote Angelita or Cenote El Pit. Learning materials included.
Connect with nature.
For anyone who wants a little adventure and a lot of calm. Three different cenotes across half a day, finishing at one of the best local taquerías in town. No experience needed, and no tank.
The season nobody forgets.
Every winter the bull sharks come to the coast off Playa del Carmen, and we drive the forty-five minutes to meet them. Two dives from the boat: the first with the sharks, the second on a shallow reef between eight and twenty metres. Advanced Open Water or equivalent, no exceptions.
Cenote map
Every cenote we dive, on one map — from Casa Cenote by the sea to the cloud in Angelita, 30 m down in the jungle. Tap one to see how deep it goes and the level it asks for.

In every price
Dive centres in Tulum quote in very different ways. Here is exactly what our prices already cover — and the one thing that is charged separately.
High quality gear, fitted before you get in. Snorkel and mask are provided on snorkel tours. Bring a swimsuit and reef-safe sunscreen.
The entry fee to every cenote on your day is in the price. No cash gate to pay at the door.
Food and water between dives. Cenote mornings run longer than people expect.
From the meeting point to every cenote and back, all day. Hotel pickup is separate — see below.
On both courses, everything you need to study is included.
The Open Water course ends with a certification recognised worldwide.

Reservations
A deposit holds the date. We confirm by WhatsApp within a few hours, send you a few questions, and you settle the balance on the day.
Before you come
Not to start. Discover Scuba takes people who have never breathed underwater, and the snorkel tour needs nothing at all. Every dive to 20 metres or shallower — the reef and most cenotes — needs Open Water or an equivalent. Anything deeper — Angelita and El Pit — needs at least Advanced Open Water or an equivalent; a Deep speciality counts. Bring the card or a digital copy and show it to your guide on the day: without it, we cannot take you on the dive.
Discover Scuba stays at seven metres (25 ft). The Open Water course and the reef stay around nine metres. Most cenote dives are planned to eighteen metres. The two deep ones go further: Cenote Angelita reaches 35–38 metres and Cenote El Pit 30–32. The Advanced course works to 27 metres (90 ft).
High quality equipment, the cenote entrance fees, transport from the meeting point to every site and back, and snacks and water. Both courses also include the learning materials. Hotel pickup is the one thing charged separately — see below. Prices are quoted in dollars and pesos; if you settle the balance in dollars, the exchange rate of the day applies.
We meet at Easy Chango Dive Center in Tulum at no extra cost. If you are staying in Tulum town we can collect you and drop you back for $20 for the whole booking. If you are outside town or in the hotel zone we cannot collect you, but we can drive you back afterwards for $10.
Three departures: 08:00–13:00, 08:30–13:30 and 09:00–14:00. You can suggest another time when you book — we check it and confirm. Two cenote dives have to start by 13:30 at the latest, and a single dive at Casa Cenote can start as late as 15:00.
Cavern diving stays inside the natural daylight zone, within reach of the entrance and always with a direct route to the surface. Cave diving goes beyond daylight and needs its own certification — a different qualification entirely, and not something an Open Water card covers.
Cenotes sit at roughly 24–25 °C every day of the year, and the reef is a little warmer. Wetsuits are part of the equipment we provide — tell us if you run cold.
Fresh rainwater floating on heavier salt water. The boundary between them refracts light, so swimming through it looks like the water has turned to oil or frosted glass — then it closes behind you and the view snaps back. It is one of the strangest things you will see underwater.
Because a tour built around you is better than a tour built around a schedule. We want to know what you have done before, what you are hoping for, and what makes you uneasy — so the day fits, rather than merely happening.
Cenotes are sheltered from wind and swell, so they dive well all year. Light beams in the cenotes are strongest around the middle of the day. Reef conditions are generally best in the spring and early summer.
