Tulum: Snorkel at the Cenotes and Underground Rivers

Tulum: Snorkel at the Cenotes and Underground Rivers offers a compelling way to experience the natural wonders of Mexico’s Yucatan Peninsula. For about four and a half hours, you’ll journey through three different types of cenotes—an open one, a semi-open, and a full cave cenote—and swim through the longest underground river in the world. Guided by knowledgeable guides, this trip is rated a perfect 5 from travelers who appreciate well-organized, authentic excursions that bring nature to life.

What we particularly like about this tour is the chance to see distinctive cenote formations—from the bright, open water of the first cenote, perfect for snorkeling, to the mysterious, shadowy depths of the caves. Another highlight is the visit to the Pet Cemetery, a quirky but meaningful stop that adds a touch of local lore and history. The fact that the tour includes a guided exploration of Sac Aktun, the largest cave in the Americas, ensures you’ll get both insight and adventure.

One potential consideration is that the tour involves snorkeling and swimming in natural settings, which may not be suitable for everyone—particularly non-swimmers or those with claustrophobia. The tour also takes place mainly outdoors, so weather can influence your experience.

This experience is best suited for travelers who enjoy natural scenery, active exploration, and aren’t afraid of a bit of water. It’s especially appealing if you love learning about geology and local lore while enjoying a physically engaging day surrounded by lush jungle and crystalline waters.
