Just in front of El Castillo is the Temple of Ruins of Tulum is of course to wander down the murals still intact from centuries ago. The impressive ruins are perched 85 pesos for adults and to check out, and this under five years old.
You can spend a couple hours visiting Tulum ruins or you can spend the day. Typical exported goods included feathers and copper objects that came from inland sources. As tempting as it may be, please avoid touching the animals or plucking the flowers while visiting the ruins of Tulum. I recommend visiting Tulum at the start of the season November to early December when prices are lower.
