A minimum of two hours is suggested to tour the Mayan ruins at Tulum. You must admire the approximately 60 buildings from a roped off walking path. The most important structures have a brief description but they do not provide enough information to satisfy a real history buff. For example, only a good tour guide would explain the three levels of the Temple of the Frescos represent the underground (Xibalba), the living (earth) and heaven (Tamoanchan).
