5 hours
Moderate—comfortable swimming ability and the ability to wade and float for short periods; not suitable for those with limited mobility without advance arrangements.
Walk the cliff-edge ruins of Tulum where Caribbean blue meets ancient stone, then slip under the earth to float through Sac Actun’s cavernous halls. This private five-hour tour pairs coastal archaeology with an unforgettable underground snorkeling experience.
The breeze off the Caribbean lifts the salt from the sea and carries it across a sun-baked path toward a low stone wall. You step through the entrance gate and the ruins of Tulum open like a stage: a compact cluster of limestone temples perched over a turquoise shelf. For two hours the guide walks you through carved stucco fragments and the Castillo’s cliffside vantage point, where waves audibly score the shore below and the coastline unfolds toward Sian Ka’an.

The cave system and cenotes are sensitive—apply reef-safe sunscreen and insect repellent before arriving to reduce contamination.
Light in the cenotes is low and directional; a small waterproof camera or a phone in a dry bag will capture the best shots.
Expect rocky or slippery surfaces at cenote entry points and tidal sand at Tulum—grippy water shoes protect feet and improve traction.
Visit Tulum ruins early to beat crowds and harsher midday sun; schedule the cave portion for warmer afternoon water temperatures.
Tulum was one of the last cities built and inhabited by the Maya, flourishing as a maritime trading port in the Postclassic period; nearby cenotes were ceremonial and lifesustaining water sources for ancient communities.
Sac Actun and the surrounding cenotes are part of protected underground aquifer systems; operators follow strict no-touch and biodegradable-sunscreen policies to limit contamination and preserve formations.
You’ll be in the water for the Sac Actun section—wear a swimsuit under quick-dry clothes to change easily.
