Its name comes from the Mayan words "Lol," which means flower, and "Tun," which means stone, meaning "Place where the Rock became Flower." They are among the largest in Yucatán.

The cave system has an approximate length of 8 to 10 km. However, the caves have been conditioned for a safe tour of approximately 1,000 m inside.

In these caves, visitors can learn about the history and geology of the last 10,000 years in the peninsula, from the Pleistocene to the contemporary era.

The astonishing caves feature incredible natural formations, 145 mural paintings, and 42 petroglyphs dating back to around 9000 BC. It is here in the cave that the earliest occupation of the Yucatán Peninsula has been found.

The tour begins at the entrance of Nahkab (beehive), where the famous bas-relief known as "The Warrior of Loltún" is located. It effectively represents a richly adorned warrior about 2.5 m tall, seemingly emerging from the cave. In style, it appears to belong to the pre-Classical period and may represent the god Chaac, the guardian of the caves.

Further ahead, you enter the main gallery where the first limestone formation is located. This area has suggestive stalactite and stalagmite figures that popular imagination has named: "Cathedral," an impressive vault approximately 30 m high, "the Great Canyon Gallery," "the corn cob," the "stalactite room," and so on. In this gallery, there is a sculpted human head with Olmec features, including a headdress and other ornaments. Additionally, pottery and other utensils, as well as mollusk and shell remains, have been found there. It is also important to highlight the "musical columns," formed by the union of stalactites and stalagmites that produce different tones when touched. There is also a magnificent gallery with a collapsed ceiling where large tree roots and sun rays enter.

In one of its chambers, known as "Huechil" (from the Maya word "Huech," meaning armadillo), excavations were carried out. In its lower levels, remains of extinct fauna such as mammoth bones, bison, felids, and others were found. In the upper levels, tools made by humans have been discovered, probably belonging to the early inhabitants of the peninsula dating back more than 7,000 years. In the "gallery of haltunes," there are deposits of natural water or suhuy ha', which were used not only to satisfy vital needs but also in divination ceremonies, as confirmed by the vessels found throughout the cave.

Another interesting attraction is the rock paintings. One wall displays negative handprints, while others feature more elaborate cave paintings depicting faces, animals, and stepped fretwork designs. Other chambers have decorations and inscriptions.

In the Hall of Inscriptions, of impressive beauty, there is a stretch of over 100 m adorned with stalactites and numerous hand and human paintings, as well as petroglyphs carved in the shape of flowers, which give the caves their name.

Finally, there is the so-called "Loltún de Pendiente Pronunciada," a gallery that leads to the surface through a staircase carved into the stone. In this area, you can see the barricades built by Mayan rebels who took refuge here during the Caste War.

It has parking, beautiful gardens, and restaurants.
