Tulum: Scuba in 2 Cenotes Including a Deep One, Pit Dos Ojos

Imagine floating in crystal-clear waters beneath a ceiling of stalactites, surrounded by limestone formations and the whispers of ancient history. That’s precisely what you’ll experience on this scuba tour through two of Tulum’s most stunning cenotes, including the famous Pit and Dos Ojos. For certified divers with Level 2 or Advanced certification, this 5-hour adventure costs around $230 per person and promises a blend of natural wonder, awe-inspiring scenery, and a touch of adventure.
What we love about this experience are the unique features of each cenote — the deep, mystical Pit with its sulfur cloud and halocline, and the famous Dos Ojos with its limestone formations and underwater caves. These sites are considered top 10 in the world, and the chance to explore them with knowledgeable guides makes this a standout choice.
That said, a common consideration is that this tour is not suitable for beginners or non-certified divers. The requirement for an advanced diver certification means you’ll need some prior experience. Still, if you’re ready for a bit of depth and a sense of exploring another world, this tour offers an incredible value for the price. It’s perfect for adventure-seekers, experienced divers, and anyone craving a once-in-a-lifetime underwater journey.

What to Expect from the Tour

Starting point: La Calypso Dive Center
Your adventure begins at La Calypso Dive Center, conveniently located in Tulum. Here, you’ll meet your guides, get fully equipped, and receive a safety briefing. The shop itself exudes a friendly vibe, with wifi available and a comfortable space to gather before heading out.
The first stop: Cenote El Pit
Cenote El Pit is unlike anything else you’ve likely seen. It’s often described as a bottomless well, with a sulfur cloud at about 25 meters, adding a mysterious, almost otherworldly element to the dive. The halocline — the natural boundary between fresh and saltwater — creates a stunning visual effect, with the water changing color and clarity as you pass through it.
Your guide will take you through caverns and passages, always within safe proximity to exits and air holes. Expect to be captivated by limestone formations and the sense of floating in a sacred, ancient space. The 40-minute dive allows ample time to explore this deep, majestic cenote. As one reviewer noted, “The sulfur cloud at 25 meters is a highlight — it’s like being in another universe.”
More Great Tours NearbyThe second stop: Cenote Dos Ojos
Next, you’ll head to Cenote Dos Ojos, famous for its stunning limestone formations, bat caves, and play of light filtering through narrow openings. The name, meaning “Two Eyes”, hints at the cenote’s twin openings, which create mesmerizing optical effects underwater.
Your 45-minute dive here offers a more accessible but equally breathtaking experience. Expect to see millions of limestone formations, fossils, and perhaps even some native animals. Many reviewers mention how Alex, the guide, made the experience relaxing and fun, sharing stories and helping everyone feel at ease.
Return and reflections
After your dives, you’ll return to La Calypso Dive Center, with plenty of time to relax and share your stories. The tour includes snacks and water, which are perfect for rehydrating after your underwater adventures.
The Experience in Detail: Why It Stands Out

This tour isn’t just about ticking off a dive; it’s about experiencing a different world. The crystal waters and unique geological features turn each cenote into a natural cathedral of limestone. The halocline phenomenon — a natural boundary between fresh and saltwater — enhances the visual experience, creating striking color contrasts and mysterious effects. As one traveler wrote, “You feel like you’re floating in another universe.”
Guides like Alex and Bebe receive high praise for their knowledge, friendliness, and storytelling skills. They make complex features understandable and help you feel completely at ease, even in the depths. This personal touch is vital in cavern diving, where safety and comfort go hand-in-hand.
The gear provided is suitable for the environment—lights, wetsuits, and everything else needed to navigate the caverns safely. This convenience means you can focus purely on enjoying the scenery and the sensation of floating through these natural sculptures.
The value of this tour
At $230, this experience offers excellent value for high-quality, guided access to two of the world’s most renowned cenotes. The small group setting ensures personalized attention, and the inclusion of all gear and transportation simplifies logistics. For certified divers, this tour will likely be remembered as one of the highlights of their trip to Mexico.
Who will love this?
If you’re an experienced diver eager to see remarkable underwater geology and enjoy guided support in a safe environment, this is a perfect fit. It also appeals to those who want a short, intense dive experience in an environment unlike any other. However, it’s not suitable for children under 16, pregnant women, or divers without certification, so keep that in mind.
The Sum Up

This scuba tour in Tulum’s cenotes offers a rare opportunity to explore some of the most stunning underwater landscapes in the world. From the deep, sulfur-laden Pit to the lit limestone corridors of Dos Ojos, you’ll be taken through natural formations that look like works of art. The guides’ expertise and the well-organized logistics make the experience both safe and memorable.
For adventurous, experienced divers looking to add a touch of magic to their trip, this tour balances great value with unparalleled scenery. The small group size, friendly staff, and top-notch equipment all contribute to an experience that’s both authentic and comfortable.
If you’re craving a once-in-a-lifetime underwater adventure in a setting that feels both sacred and surreal, this tour is well worth considering.
