here is the translation from spanish to english of the sign:
This is an installation designed specially for the orangutans and promotes natural behavior of the species, such as climbing,brachiation and travel at great heights as they would in the tropical forest.
The towers have a height from 15 to 25 meters.Only the first, which is located inside their exhibit, has a ladder that lets them climb up and down, and also a wide platform that allows them to rest and watch. The other towers have a cilinder that does not allow descending.
There are 8 towers connected by 2 pararell cables.
