The CEAVG has audio-video guides that allow visitors to have greater autonomy both while visiting the permanent exhibition and while enjoying the trails on the outside.

The audio-video guides are available in Portuguese and in English, with or without subtitles, and relay the information while visitors stop in each of the points of the exhibition and/or trails (identified by numbers).

The audio guide system is automatic, but if visitors prefer they can manually select the explanations associated with each stopping point. Visitors can also manually adjust the volume of sound.

The devices are equipped with a two headphone jack that may be simultaneously used bu two visitors.
