Four kilometers west of Viñales village on the side of Mogote Pita is a 120m-long painting. Leovigildo González Morillo, a follower of Mexican artist Diego Rivera, designed it in 1961 (the idea was hatched by Celia Sánchez, Alicia Alonso and Antonio Núñez Jiménez). On a cliff at the foot of the 617m-high Sierra de Viñales, the highest portion of the Sierra de los Órganos, this massive mural took 18 people four years to complete.
The huge snail, dinosaurs, sea monsters and humans on the cliff symbolize the theory of evolution and are either impressively psychedelic or monumentally horrific, depending on your viewpoint. You don't really have to get up close to appreciate the artwork, but the admission fee is waived if you take the overpriced, CUC$15 lunch at the on-site restaurant. Horses are usually available here (CUC$5 per hour) for various excursions.
