Casa de la Cultura has rotating art exhibitions and cultural events, completely free. Beautiful colonial building downtown featuring local Yucatecan artists.

Museo Maya de Cancún is only 70 pesos with excellent collection of artifacts from peninsula sites. Temporary exhibitions usually well curated.

Check municipal website for free concerts and dance performances at Parque de las Palapas. Usually Thursday and Sunday evenings where local families actually hang out.

Centro Cultural La Isla occasionally has free art workshops and live music. Attached to shopping center but cultural programming is legitimate.
