Avilon Zoo is currently the largest zoological institution in the Philippines in terms of land area and collection of animals.

The 7.5-hectare (19-acre) facility located in Rodriguez, Rizal houses more than 3,000 specimens of exotic wildlife representing more than 600 species of birds, mammals, reptiles, amphibians, freshwater fishes and invertebrates.

The zoo has a diverse collection of Philippine native fauna, most of which have been bred successfully in captivity through Avilon's ex situ conservation programs.

At Avilon Zoo guided tours and educational field trips offer guests the opportunity to learn about wildlife.

Avilon has successfully bred the Gray's monitor lizard (Varanus olivaceus) or "butaan" ex situ (in captivity).
