What Makes Sac Actun and Pet Cemetery So Special?
What is Cenote Pet Cemetery?
Cenote Pet Cemetery (sometimes called “Cementerio de Mascotas”) is a semi-open cenote located within the Dos Ojos Park, just north of Tulum. The name comes from the many ancient animal bones discovered in the cavern—remnants of creatures that lived thousands of years ago when the cave system was dry. Despite the spooky name, the cenote is a peaceful, otherworldly place filled with natural beauty and silent wonder.
Part of the Legendary Sac Actun System
This cenote is one of the many access points to Sac Actun, the longest underwater cave system in the world. Spanning more than 370 kilometers (230 miles) of flooded passages, Sac Actun is a sacred and geologically significant wonder that has captivated explorers and scientists alike.
Cenote Pet Cemetery features dramatic limestone formations, submerged tunnels, and dazzling beams of sunlight that pierce the water—ideal for snorkeling and photography. While diving deeper into Sac Actun requires certification and experience, snorkeling in the Pet Cemetery section is suitable for confident swimmers with a sense of adventure.
