The peaceful park-like setting of the area adds to the pleasure of contemplating the raised mounds of earth supported around their bases by large rounded stones and interconnected by cobblestone walkways. It is assumed that buildings once stood atop these mounds, but because they were built of perishable materials, no evidence of them remains. Other preserved features include a still-functioning aqueduct system, burial sites, and numerous petroglyphs. Many high-quality examples of pottery, gold, and stone workmanship on display at the National Museum came from this site. Archeologists estimate that half of the village area still awaits excavation.

Given that the monument only protects 217 hectares of land, wildlife viewing potential is rather limited. Among the creatures that might be seen at Guayabo are the Nine-banded Armadillo, Montezuma Oropendola, Central American Coral Snake, and Blue Morpho Butterfly. A variety of orchids also grow in the trees in the wooded portions of the monument grounds.
