July 19th, 2012. The 4 monkeys have a very steep enclosure that is filled with mock-rock from floor to ceiling. Vines are really cement carvings on concrete trees, and there are statues of a weird monkey-headed king, lots of stairs and the ruined temple theme looks amazing to many visitors but the monkeys have absolutely nothing natural to smell or touch. A large grassy field with a few boulders would probably be a much more enjoyable habitat for them to romp around in.
