Last month I visited Ark Avilon Zoo for the first time. It is located at Frontera Verde, Ortigas Avenue corner C-5, Pasig City. Just at the back of Fun Ranch. Since I just commute going there I had a hard time finding the venue. I suggest you ride a cab if you're going there for the first time.
The zoo opens from Monday to Thursday: 9:00 am - 6:00 pm and Friday to Sunday: 10:00 am - 7:30 pm (informations lifted from Ark Avilon Zoo's Facebook Page)
Ark Avilon Zoo is actually different from Avilon Zoo which is located in Rodriguez, Rizal. But they're from the same foundation, Avilon Wildlife Conservation Foundation. 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.
Their Official Facebook Page says, "Ark Avilon Zoo is the only interactive indoor zoo in the Philippines.
