Visitors can get within a couple of inches of the lion-tailed macaques, with no bars or wooden beams in the way. A densely planted, lush, green jungle is the exhibit, and it is one of the best primate habitats that I've ever seen.
Exremely good zoo and the only better lion tailed macaque exhibit I can think of is San Diego Zoo's macaque exhibit in Sun Bear Forest Another interesting lion-tailed macaque exhibit is Toronto Zoo's Toronto Zoo > Videos You'll see why with the video (It has nothing to do with the size and space of the exhibit, more to do with its innovativeness and management)
San Diego's exhibit has a special place in my heart...I donated to its construction back in 1985 or so, my name is on the donor plaque!
That is helpful, but there is also an element of design . They put a lot of effort into maintaining green enclosure too, I assume. How many primate enclosures to not look like the above?
