When we dock in Costa Maya, we'll head out to visit some Mayan ruins. Kohunlich ruins include a sunken palace, acropolis, ball court, courtyards and the main attraction - the masks. We'll climb the pyramid-like temple for a view of the unique 10-foot high sculpted masks of the sun god 'Kinich Ahau.' Built before 500 A.D., these marvelous masks still retain some of their original colored stucco.
