The ancient Mayans are believed to have lived in El Rey between 300 AD until 1550 BC, when the Spanish conquest began. El Rey, meaning "The King" in Spanish, was named for a sculpture of a nobleman and a skull found at the site honoring the Mayan sun god.
While the ruins are fascinating to wander around, there is also another population that now inhabits the old Mayan city: iguanas. Hundreds of iguanas now live in the park area and give El Rey ruins a unique beauty. This place is a must see while in Cancun.
I believe we paid around $3.00 or $5.00 each, but it was worth every penny.
