Under Tulum’s Surface: A Day Swimming the Riviera Maya’s Hidden Cenotes
A full-day plunge through four cenotes and a turquoise lagoon—how to experience Tulum’s underground rivers with purpose
The first breath of air under the jungle canopy is different—cooler, damp, laced with the mineral bite of limestone and the faint green perfume of wet leaves. You step off the minivan on a narrow dirt drive and the world tightens to a soundtrack: a bird’s intermittent click, water dripping somewhere below, a guide calling out instructions in Spanish and English. The cenotes aren’t a single place but a stitched landscape of sinkholes, cavern swims and forested pools where the Yucatán’s underground rivers surface like theatrical reveals. On this 11–12 hour trip out of Playa del Carmen you’ll visit four of them—Multum Ha, Zacil-Ha, Cenote Zemway—and finish the day in the shallow turquoise halo of Laguna de Kaan Luum—each one a different version of freshwater clarity and limestone drama.
Trail Wisdom
Wear Water Shoes
Limestone edges are slippery and jagged—closed-toe water shoes protect feet and provide grip during short walks and ledger drops.
Use Reef-Safe Sunscreen
Regular sunscreens damage freshwater ecosystems; a biodegradable, reef-safe formula reduces harm to the aquifer.
Pack a Small Dry Bag
Keep your phone, a spare shirt and snacks dry—many cenotes have limited or no lockers at the entry point.
Respect Fragile Formations
Do not touch stalactites or stalagmites and follow guide instructions in caverns to preserve formations and archeological layers.

Conservation Note
These cenotes feed the Yucatán aquifer; favor operators that require reef-safe sunscreen and limit group sizes to reduce ecological impact.
Cenotes were sacred to the Maya as sources of life and ritual—archaeological finds in some cenotes include offerings and tools.
Seasonal Guide
spring
Best for: Clear water visibility, Fewer swimmers after spring break, Comfortable air temperatures
Challenges: Occasional afternoon rain, Higher pollen counts
Spring (March–May) is warm, visibility is generally good, and crowds are moderate—plan early starts to miss heat and showers.
summer
Best for: Lush jungle scenery, Long daylight hours, Warm water
Challenges: Heavy afternoon storms, Higher humidity and mosquitos
Summer brings verdant surrounds and frequent rain—midday storms are common but short-lived; mornings are best for swimming.
fall
Best for: Off-peak travel, Warm sea temperatures, Photogenic storm clouds
Challenges: Hurricane season windows (Aug–Oct), Variable road conditions
Fall can offer quieter cenotes but carries hurricane season risk—check weather and cancelation policies before booking.
winter
Best for: Dry, clear conditions, Peak visibility, Cooler evenings
Challenges: Higher tourism demand, Lower availability of preferred time slots
Winter (Nov–Apr dry season) is ideal for clear water and minimal rain—book early to secure prime departure times.

Common Questions
Are the cenotes safe for children?
Many cenotes on this tour are family-friendly and offer shallow areas or life jackets, but check age restrictions with the operator and supervise children at all times.
Do I need to be a strong swimmer?
A basic comfort in open water and the ability to swim short distances is required; life jackets are provided for anyone less confident.
Is snorkeling gear provided?
Most operators supply basic masks and snorkels and life jackets—bring your own mask if you prefer a personal fit for extended photography or comfort.
Can I bring my phone and camera?
Yes, but use a waterproof case or dry bag—cameras are welcome but avoid flash in fragile cavern environments unless instructed otherwise.
Are cenote jumps included?
Some cenotes on the itinerary, like Zacil-Ha, have platforms for jumping—participation is optional and subject to guide safety decisions.
What about restroom and changing facilities?
Many managed cenotes offer basic facilities and changing areas, but they vary—pack a towel and quick-dry cover-up for comfort.
What to Pack
Reusable water bottle (stay hydrated), reef-safe sunscreen (protect water), water shoes (protect feet), dry bag (protect belongings)
Did You Know
Cenotes are sinkholes formed when limestone bedrock collapsed, exposing groundwater—the Yucatán’s cenotes feed one of the largest underground freshwater systems in the world and were sacred to the ancient Maya.
Quick Travel Tips
1) Book early in high season; 2) Bring cash for small vendor purchases; 3) Arrive hydrated and well-rested; 4) Confirm pick-up time the night before
Local Flavor
After the tour, head back to Playa del Carmen’s Quinta Avenida for fresh ceviche and a cold beer, or detour into Tulum town for cochinita pibil and a mezcal tasting at a small bar—street vendors near cenotes also sell fresh coconut and handmade tortillas.
Logistics Snapshot
Closest airport: Cancun International (CUN); Driving distance: ~1–1.5 hours from Playa del Carmen to the Tulum-area cenotes; Cell service: Good in towns, spotty at remote cenotes; Permits/fees: Cenote entrance fees typically included in organized tours—bring cash for souvenirs.
Sustainability Note
These cenotes are part of the peninsula’s fragile aquifer—use reef-safe sunscreen, avoid soaps or shampoos in the water, follow guide instructions, and pack out all trash.
