Delve into the Profound History and Spiritual Importance of the Maya & ATM Cave

The entrance of ATM Cave was first encountered by the Maya around 300–600 AD, but it was during the period of 700–900 AD that substantial ceremonial activities unfolded.

This profound connection between the cave and Maya culture enriches the experience of every visitor, transforming it into a pilgrimage site for many.
